About Release 4.0.00
These release notes describe the system requirements, new features, and limitations that apply to Release 4.0.00 of the MGX 8850 and the new MGX 8830 multiservice switch. These notes also contain Cisco support information.
MGX Release 4.0.00 helps fulfill the original MGX feature expectation of direct cell bus service module (CBSM) support on both feeder and routing nodes, while positioning the high end of the product line for next-generation broadband networking.
With this release, most of the Narrow Band Service Modules currently supported on the MGX 8850 (PXM1) are now supported on the MGX 8830 and MGX 8850 (PXM1E) and MGX 8850 (PXM45). This brings to service providers unparalleled flexibility in the way they choose to terminate service access in their networks.
MGX Release 4.0.00 also brings to the industry the first true next-generation multiservice platform with a new set of Service Modules that put the MGX 8950 switch's powerful backplane throughput at the fingertips of network architects. An MGX 8950 chassis can now be configured with the highest broadband port density available in the industry and up to 10G bandwidth available from each of the 12 Service Module slots.
In support of this unprecedented multiservice throughput, a slew of PNNI features are also being released to facilitate continued expansion of MGX networks.
These release notes complement the technical manuals listed in the "Related Documentation" section.
Note Release notes for MGX 8950, Release 4.0.00, are combined with these release notes.

New Features and Enhancements in Release 4.0.00
Note Starting with this release, you will see reference to cell bus service modules (CBSMs). CBSMs were formerly called narrow band service modules (NBSMs). As the MGX product line has grown, the narrow band distinction is no longer appropriate. CBSMs use the MGX cell bus for customer traffic instead of the serial bus used by cards such as AXSM and FRSM-12-T3E3.
Refer to the "Acronyms" section for definitions of acronyms used in these release notes.Release 4.0.00 contains the following new features:
•Closed User Groups (CUG)
•Preferred routes for PNNI Multipeer Group Networks
•Point to Multipoint SVC/SPVC support (P2MP)
•Increased number of Signaling Interfaces
•Virtual trunks support in PXM1E
•Virtual UNI support in PXM1E
•AXSM-E and PXM1E as Upstream to Feeder Nodes and IGX Feeder to MGX 8850

Closed User Groups
The Closed User Groups (CUG) supplementary service enables network users to form groups, to and from which access is restricted. A network user may be associated with one CUG, multiple CUGs, or no CUG. Members of a specific CUG can communicate typically among themselves, but in general not with network users outside of the CUG. Specific network users can have additional restrictions preventing them from originating calls to, or receiving calls from, network users of the same CUG (Outgoing Calls Blocked or Incoming Calls Blocked). In addition, a network user can be further restricted in originating calls to, or receiving calls from, network users outside of any CUG membership defined for the network user (Outgoing Access or Incoming Access.).
The feature is based on the ITU-T Q.2955.1 recommendation.
Platforms
Closed User Groups is supported on:
•MGX 8850 (PXM45)
•MGX 8850 (PXM1E)
•MGX 8830
•MGX 8950

ITU-T Q.2955.1
Preferred Routes for PNNI Multipeer Group Networks
Preferred routing of connections provides the network operator a means of bypassing the PNNI route selection, and configuring a specific path through the network which a connection will follow. Preferred routes can be configured as either Preferred or Directed routes. A Preferred route is one which will follow the configured path if available, but will revert to a PNNI-selected route if the preferred route is not available. A Directed route is one which will follow only the configured path; if the configured path is not available, the connection will remain unrouted.
Preferred routes can be specified for SPVCs from source switch to the destination switch end-to-end using CLI or SNMP. The end-to-end preferred route for connections can span across multiple peer groups. The implementation is based on PNNI 1.1 specification.
Platforms
This feature is supported on:
•MGX 8850 (PXM45)
•MGX 8850 (PXM1E)
•MGX 8830
•MGX 8950
References
PNNI 1.1
Point-to-Multipoint SVC/SPVC Support
The SVC/SPVC point-to-multipoint (P2MP) feature offers the ability for one root SVC/SPVC connection to establish a simple tree topology to one or more leaf connections. The data traffic is uni-directional from root multicast to all leaves, i.e., what is sent from the root data channel is received by all leaves. From the root, leaves can be added to the connection using SETUP/ADD_PARTY signaling messages. Point-to-multipoint is a mandatory feature described in UNI 3.0, UNI3.1 and UNI4.0 specs. The implementation is compliant with in Q2971.
Platforms
This feature is supported on:
•MGX 8850 (PXM45)
•AXSM/B on MGX 8950
•AXSM/B on MGX 8850 (PXM45)
Note AXSM/B support is limited due to the capability of the hardware. P2MP connections and throughput are limited.

The PXM1E PNNI Controller offers redundancy, offer hitless operation, and Y-Redundancy (1:1) will be supported in PXM1E for the 155 interface.
Service Modules will have 1:N redundancy and 1:1 redundancy as supported by the individual service modules
Automatic Protection Switching Support
Automatic Protection Switching (APS) 1:1 and1+1 for both the Bellcore GR-253 and ITU-T G.783 Annex-A and Annex-B standards will be supported for the OC3 and STM1 interfaces. The MGX-8850-APS-CON plane is required for APS functionality.
Modular Transceiver Support in the New 8-port OC3/STM1 Back Card
The PXM1E will support a single universal back card capable of supporting single-mode and multi-mode fiber connectors for the different reaches in OC3 and STM1.
External field-replaceable transceivers for SMF-IR, SMF-LR and MMF, purchased by the customer, will be supported.
UNI connection support in PXM1E-16-T1E1
In a previous software release (3.0.10), the PXM1E-16-T1E1 card provided support for IMA trunking. In the MGX 4.0.00 release, the same card will support both native ATM UNI and IMA UNI endpoints. Sixteen T1/E1 ports can be mixed and matched for either native UNI or NNI ports and IMA UNI or NNI ports.
ATM Routing in PXM1E
The PXM1E-based switches support the ATM Forum standard PNNI routing/signaling based on the same baseline used for MGX 8850 (PXM45) and BPX/SES systems. It can be a peer to the PXM45-based switches in the single peer group and participate in multipeer groups.
Connection Management
Supports different types of connections—SVC, SVP, S-PVC, and S-PVP. UNI 3.X/4.0 signaling and ILMI are used to setup SVCs and SVPs.
PXM1E will support 13,500 local switching connections and 27,000 routed connections.
Cell Bus Service Module Support
A cell bus service module is an MGX service module that uses the MGX cell bus to transport customer traffic between that service module and other services modules or PXM uplinks. Traditionally, the CBSMs were called narrow band service modules (NBSMs).
For a summary of service modules supported in MGX 8830 and MGX 8850 (PXM1E), please refer to Table 2
Virtual Trunks Support in PXM1E
Virtual trunks will be supported in the PXM1E ports. A maximum of 31 (physical and virtual) trunks can be supported in a PXM1E card. The feature will be supported in 4-port OC3/STM1, 8-port T3/E3, 8-port OC3/STM1, 16- port T1/E1 and the combo PXM1E cards. SVC, SPVC and SPVP connections can be routed over the virtual trunks.Virtual trunks can originate and terminate between PXM1E, AXSM/A, AXSM/B, AXSM-XG and AXSM-E cards.
Virtual UNI Support in PXM1E
A new port type called Virtual UNI (VUNI) and Enhanced Virtual UNI(EVUNI) is defined in addition to the already defined port types UNI, NNI, VNNI (Virtual Trunk). This feature benefits both the MPLS and PNNI control plane.
Feeder Trunk support in PXM1E
PXM1E ports can accept feeder trunks in any port. IGX 8400, MGX 8230, MGX 8250 and MGX 8850 (PXM1) can be added as feeders to MGX 8830 and MGX 8850 (PXM1E).
PXM1E Diagnostics
Both HMM and online diagnostics report alarms in the Hardware Alarm category under the card alarms.
•HMM reports alarms for all devices when error thresholds are crossed. Further information can be obtained via the CLI dspdeverr <device>. This CLI will have to be issued for each device to ensure that all relevant errors have been observed. The alarm raised by the specific instance of the device (for example, QE1210 - 0 or 1) will also be available in the dspdeverr CLI.
•The CLI dspdiagerr online indicates whether there is error reported by online diagnostics. Further information regarding the error can be obtained from the event logs via a filter using CLI dsplog -mod PXMD.
POST test results printed to the console immediately after execution may display failures. These may be due to tests being attempted for devices not present on the particular PXM1E-board (such as the second ATM policing device on the PXM1E-4-155). The tests are based purely on device offsets and can display spurious results. To confirm/rule-out real and relevant tests, please use the following examples:
Example 1 PXM1E-4-155: ATM policing device 2 and framers 2 and 4 do not exist: Following shows all relevant test cases passed. Although framers 2 and 4 show passed below, those two cases must be ignored.

Limitations, Restrictions, and Notes for 4.0.00
This section includes information about limitations, restrictions, and notes pertaining to MGX Release 4.0.00.
Limitations
When configuring virtual interfaces (i.e., VUNI, VNNI, EVUNI, EVNNI), the physical interface must be of all one ATM header type, either UNI or NNI. Keep in mind that the signaling that is applied to a virtual port is independent of the actual virtual port ATM header. The only limit will be that the VPI value must be within the UNI ATM header limitations
Upgrading to 4.0
•The statistics associated with the on-line and off-line diag tests (viewed via dspdiagstatget corrupted after an upgrade to 4.0. A clrdiagstat CLI command should be issued against all slots after an upgrade has been completed. Please see CSCea42260 for more formation.
•The persistent link database is not supported on PXM45(A) cards. Therefore, if the persistent topology gateway node of a peer group has PXM45(A) cards, then before this node is upgraded to the 4.0 release, another node with PXM45/B/C cards have to be configured to be the persistent topology gateway node for this peer group. The node with the PXM45(A) card should then be disabled as the gateway node. Then, proceed with the upgrade for this node.
•To upgrade to 4.0, you will not need to upgrade to 3.0.20 if running 3.0.10.
•If you upgrade from 3.0, 3.0(21.100) or any pre-3.0 release to 4.0, the node will report a few instances of the following error message during burnboot and switchcc:
–Error Log for Slot 07: Error Num 5
Event Logged:
07I00229 04/02/2003-17:49:14 SMGR-4-INVD_RET
E:00005 tStDnld19 smgrApiSHMFileDownload
smgrApiSHMFileDownload: Card not in correct state•Setup and operation of the Preferred Route feature is changed between MGX Release 3 and MGX Release 4. Please refer to the MGX Software Configuration Guide listed in the "Related Documentation" section for information on how to migrate Release 3-based preferred routes into a Release 4-based network after the 4.0 upgrade is complete. For your convenience, the Preferred Routes information from the MGX 3.0.20 release notes is repeated in these notes, in the following section.
Caution Due to significant differences in the Preferred Route feature between Release 3 and Release 4, all Preferred Route information is lost during migration to Release 4. To facilitate the recreation of the preferred routes, make sure a record of the routes is available before starting the upgrade.
Preferred Route
•Upgrading a preferred routing configured connection from any Release 3.0.x will be nongraceful. In a future release, the configuration of the preferred route identifier information for each connection will be supported on the Service Module cards instead of on the PXM controller. During the upgrade, the preferred route identifier information for each connection will be lost and the preferred route identifier needs to be reprovisioned on the Service Module cards. Also, the preferred route table at the PXM controller will be lost. Connections that have already been routed with preferred routing will remain, and there will be no alarms for these connections.
•The preferred routes can be specified only within a PNNI single peer group meaning all the nodes in the preferred route lie within the same peer group.
•All the nodes in the network should be running Release 3.0.00 software to use the preferred route feature.
•All the links specified in the preferred route should be PNNI links.
•If a node in the PNNI network changes its PNNI node ID, the old entry in the persistent topology database in all the nodes in the network need to be deleted. If any of the preferred routes in any nodes in the network contains the changed node as one of the hops, the preferred route(s) must be modified using the new table index (in the persistent topology database) allocated for the changed node.
•If a node in the PNNI network is deleted via configuration commands from the persistent topology database, if any of the preferred routes configured at that node (where the delete command is executed) contains the deleted node as one of the hops, the preferred route(s) must be deleted/modified manually.
•If a node in the PNNI network is removed via physical decommissioning, and if any nodes in the network had some preferred routes that contain the removed node as one of the hops, the preferred route(s) must be deleted/modified manually.
•Due to differences in physical port numbering, non-Cisco nodes can only be the terminating nodes in a preferred route.
•When a connection is routed on a route other than its preferred route and if the preferred route becomes available, the connection would not be automatically derouted to route back to its preferred route. The user has to deroute/reroute by using configuration commands (optrte, rrtcon, dncon/upcon etc.).
•The preferred route configuration is available using only the CLI at the PXM controller. The configuration of the preferred route will be available with the CWM proxy service agent in a future CWM release.
PXM45/C
Supported only on MGX 8850 (PXM45) and MGX 8950, starting with release 4.0.00.
192 Signaling
This feature has been tested on PXM45/B and PXM45/C on MGX 8850 and MGX 8950 platform only. Based on the assumption that the limit for signaling interface of PXM45(A) will remain unchanged, and that for PXM45/B and PXM45/C, the number of signaling interfaces supported will be increased to 192 and the number of physical ports supported will be 4000 (same as the limit for MGX 8850/8830 PXM1E when supporting narrow band service modules).
Closed User Group (CUG)
The following notes pertain to the CUG feature:
•If a Closed User Group(CUG) membership configuration is modified in any manner, the CUG interlock code information maintained by the SVC connections which have already been routed is not altered.
•The CUG feature is not supported on nodes which are configured with right-justified E.164 addresses using cnfe164 justify.
•This feature allows a maximum of 100 CUGs per AESA address at a UNI interface.
•This feature allows CUG membership to be provisioned at a maximum of 200 AESA addresses per node, assuming that none of the AESA addresses are assigned to multiple interfaces. However this limit is not enforced in the software.
•If some of these AESA addresses are assigned to more than one interface, the number of AESA addresses supported by this feature is correspondingly reduced. For instance, if all the addresses on the node are assigned to two interfaces, CUG membership should not be provisioned for more than 100 addresses per node.
•When configuring CUGs on a node, up to 20000 different 20-byte AESA administrative addresses can be specified (200 address with 100 CUGS each) in the leading portion of the CUG interlock codes within the node.
•The space taken by these CUG IC AESAs is shared with that used to store the calling/called party numbers of the in-progress or active connections.
•This feature is now supported on PXM45(A) on MGX 8850 switches
Point to Multipoint SVC/SPVC Support
The following notes pertain to the Point to Multipoint (P2MP) feature:
•This feature is not supported in PXM45(A) and AXSM-E.
•There is a switch xbar design limitation on AXSM-XG specific to P2MP. The Humvee based cards can have only 8 serial links turned on while the Europa based cards would have their 16 serial links enable. When all the targets (leaves) are humvee based, the Europa is getting grants on only 8 links.
•Release 4 is not UNI40 and PNNI P2MP conformace compliant.
•There is an AXSMB switch xbar design limitation for P2MP traffic wherein if some of the ports are shut down and if there are p2mp leaves present in those ports, the cells of those leave will not be delivered while other leaves might get traffic.
AXSM-32-T1E1-E/PXM1E-16-T1E1
•IMA version fall back is part of IMA group operation. If a group is configured with version 1.1 and it is connected to a far end group which is configured with version 1.0, this group will fall back to version 1.0.
•The IMA link LIF(Loss of IMA Frame) and LODS(Link Out of Delay Synchronization) defect integration times are configurable.
•ATM layer configuration for line and IMA ports takes an additional parameter, AIS enable. It is enabled by default.
•In T1 mode, payload scrambling is disabled by default and in E1 mode it is enabled by default on all lines and IMA groups.
•Only 10 SVC calls/sec is guaranteed
•FDL support for Loopback code detection is not supported
•Far End Line Performance counters are supported only for E1.
•They are not supported for the T1 interface.
•HMM support is not available for the IMA and the Framer devices.
•When there is switchover, tt can take up to 3.5 seconds for the
•IMA groups to recover. Data is lost until the groups recover.
•Auto-restart(persistent Rx IMA ID) feature is not supported.
•IMA group cannot have links from upper and lower bays together.
•ITC clocking mode on IMA is not supported.
•One way transmission delay of more than 500 msec on the T1/E1 IMA links is not supported
•There is 5ms fluctuation on IMA delay tolerance.
•While the IMA group accumulated delay is being removed with "clrimadelay", the following apply
•Any changes to this IMA group configuration are temporarily blocked/.
•Any changes in the FE IMA links in this group can cause the NE IMA group to restart.
•The VC and COSB thresholds are updated as and when the links are added/deleted from the IMA groups.
•The thresholds for the connections added when there are N links in the group can differ from connections added when there are (N+1) links in the IMA group.
•BERT is only supported on the T1 interfaces. It is not supported on E1 interfaces.
•The port number in the pnport(shelf.slot:subslot.port:subport) could be a random number.
•The user should not interpret this number as line or IMA group number. Refer to DDTS CSCdy08500
Narrow Band Service Modules and RPM-PR
When switchredcd is done and a PXM switchover (either through switchcc/resetcd on the PXM or due to a failure) happens at the same time (CSCea36485):
•Conditions: switchredcd is run from PXM Command Line to perform CBSM Switchover. PXM switches over (manual or automatic) before the SM switchover is completed.
•Symptom: SM did not switchover after switchredcd
•If the PXM switches over before the CBSM switchover completes, the following issues can be seen:
–the SM Switchover may not be complete and the standby card will be in an indeterminate state. The dspcd command from PXM will still show it as 'standby' and later switchver (due to Active SM removal or reset) will fail, causing Loss of Traffic. The switchredcd command will also fail.
–The switchredcd from PXM again will cause the failure since the standby SM will not be able to allocate memory.
–Work round: Reset the standby Service Module card.
•CBSM feature is not available for PXM45/A
•CBSM (max dax con) 7200
•CBSM (max non-dax) 27K.
AXSM-E as Upstream to Feeder Nodes
These notes apply to the AXSM-E:
•The AXSME cards only work on the MGX 8850 (PXM45).
•Above T3/E3, the AXSM-E port density is only half the density of AXSM and AXSM/B.
•The highest port bandwidth supported on AXSM-E is OC-12/STM-4.
IGX Feeder
When an IGX is added as a feeder to a SES/BPX or MGX node, it will have a default node number, this node number may not be unique within the network. If it is not unique then it needs to be modified to a unique node number by issuing cli command "rnmnd <x>" where x should be unique with respect to all other auto-route nodes. To find the other node numbers, use cli command "dspnds +n". Failing to do so, CWM Databroker may have incorrectly formed hybrid connection database, the CWMGUI may show the connection as incomplete.
Policing Accuracy for PXM1E
There is a limitation regarding the policing accuracy for the PXM1E. The policing rate is defined as 50000000/PCR. If the PCR is comparable to the OC12 line rate (1412830), the policing rate parameter is a relative small number (50000000/1412830 = ~35.38996). Since integer division is performed, the decimal values are truncated. As a result, the policing parameter cannot be calculated accurately. Moreover, the policing rate parameter is stored in an exponent (5-bits) and mantissa (9-bits) format, so this format cannot represent a small number very accurately. Combining the above two factors, a 100% accurate policing parameter cannot be configured.
To ensure that the user gets the rate that they have specified, the software configures policing at the next larger rate which the hardware can support. For example, if we program a connection with PCR = 1400000, the software programs the actual policing rate to be 1428571. For a worst case scenario, if the user configures a VBR2 connection with a PCR of 1400010 and the ingress user traffic is 1428570, there won't be any policing because the ATM policing device would police at rate 1428571 only.
Maximum Threshold Accuracy for PXM45 and PXM1E
There is a limitation regarding the maximum threshold accuracy for the PXM45 and PXM1E. The Qbin threshold and VI rate are stored in the form of exponent and mantissa, and some accuracy is lost in expressing the real rate. In testing the thresholds, the lack of accuracy is compounded with both of the Qbin and VI rate (draining rate) and therefore we cannot calculate an exact 100% correct discard rate.
To ensure that the user gets the rate that they have specified, the software configures Qbin depth at the next larger rate which the hardware can support. As a result, Int. Cell Gap(ICG) and Relative Service Delay(RSD) are truncated.
PXM1E-Based Switches
The following notes apply to PXM1E based switches (that is, MGX 8850 (PXM1E) and MGX 8830):
•There is no CLI retrieve POST (Power On Self Test) display.
•POST can only be displayed on the console during boot up.
•Y-red is not supported on the MCC Electrical back card
•For inter-card APS to work on the PXM1E-8-155, and one front card is missing or not available, both backcards have to be present. A front card cannot drive the alternate trunk-backcard when its own local trunk-backcard is absent.
•MPLS controller is not supported on PXM1E.
•PXM1E Clock source is supported by CESM, and AUSM narrow band service module cards. CESM and AUSM can provide one clock source, either primary or secondary.
•Only SPVCs and SPVPs are supported on narrow band service modules. SVCs are not supported on CBSM (Cell Bus Service Module).
•There is no bandwidth CACing support on the narrow band service modules, except for the RPM card, which is checked against the OC3 card rate. For example, for a given RPM, the bandwidth allocated to all connections may not exceed OC3 rate. Bandwidth CACing is supported on the PXM1E uplink port.
•The maximum bandwidth to be distributed among narrow band service modules is ~ OC10 while traffic on the network interfaces on PXM1E can achieve true OC12 line rate.
•Traffic should be balanced between the Cell Bus Controllers to achieve the OC-10 rate. The traffic should be distributed equally at a rate of about OC-5 on the two Cell Bus Controllers. The Cell Bus Controllers can't load share to achieve OC-10 with one Cell Bus set at an OC-6 rate, and another Cell Bus set at an OC-4 rate. Anything above OC-6 will be dropped. However, if only one Cell Bus Controller is used and the other Cell Bus controller is not used, then it can achieve OC-10. On an 8850, the CBCs are split between the left and right side of the chassis: CBC0 supports slots 1-6 and 17-22 and CBC1 supports slots 9-14 and 25-30. On an 8830, CBC0 supports slots 3,5,10, and 12 and CBC1 supports slots 4,6,11, and 13. Balance is achieved by planning the distribution of your cell base card by evenly distribute from left side of chassis and right side of chassis.
PXM1E Hardware Limitations
These are the PXM1E hardware limitations:
•For inter-card APS to work on the PXM1E-8-155 with one front card missing or unavailable, both backcards have to be present. A front card cannot drive the alternate trunk-backcard when its own local trunk-backcard is absent.
•During hardware upgrade from PXM1E-4-155 to PXM1E-8-155, at the time when the inserted card types are different (one PXM1E-4-155 card set and onePXM1E- 8-155 card set), the standby trunk-backcard functionality will not be available. Therefore, LED functionality will not be available, and APS lines will not work on that backcard.No modular optical transciever(SFP-8-155)-mismatches will be reported for that backcard. No SFP-8-155 mismatches will be reported during hardware upgrades.
•Since the PXM1E-4-155 and PXM1E-8-155 backcards support LC and SC interfaces respectively, the following limitation/restriction applies. For hardware upgrade from PXM1E-4-155, to PXM1E-8-155, it is required that, after the first PXM1E-4-155 card set is replaced by the PXM1E-8-155 card set, any cabling for the PXM1E-8-155 interfaces is updated with a LC-SC converter. Similarly, after the second card-set is replaced, the same needs to be done for the interfaces on the new card-set. If this is not done, the upgrade will not be graceful and will be service affecting, until appropriate cables are setup.
•When MGX-8850-APS-CON is used, and one trunk-backcard is removed, care must be taken to screw the remaining backcard in completely, to ensure that the contacts are complete.
•MGX-8850-APS-CON
–The Combo card does NOT require a mini-backplane. The PXM1E-8-155 REQUIRES a mini-backplane. The PXM1E-4-155 card does not require a mini-backplane but it is RECOMMENDED that one be inserted. This is to support graceful upgrade to PXM1E-8-155 cards in the future. Since the PXM1E-8-155 card requires a mini-backplane, if one is not already present when upgrading from PXM1E-4-155 to PXM1E-8-155, the upgrade cannot be graceful.
•Standby alarms not raised for HMM and Online Diagnostics. Alarms will NOT be raised for HMM and Online Diagnostics on the Standby card.
Reserved VCIs
Here are the reserved VCIs that the customer cannot provision:
•vpi=0, vci=5 is used for SSCOP for UNI signaling ports.(If the port is configured for non signaling (univer = none) then no VPI/VCI is reserved.)
•VUNI uses configured vpi and VCI=5 for SSCOP.
•EVUNI uses minimum vpi and VCI=5 for SSCOP.
•NNI uses vpi=0, vci=18 for PNNI RCC.
•VNNI uses configured VPI for the port and the VCI=18 for PNNI RCC
•EVNNI uses minimum VPI and the VCI=18 for PNNI RCC
•vpi=0, vci=16 is used for ILMI if ILMI is enabled. VUNI, VNNI uses configured VPI for the port and VCI=16 for ILMI. Similarly, ILMI for EVNNI or EVUNI uses minimum vpi and vci=16.
•If MPLS is configured, vci=33 in the similar fashion as above.
•If NCDP is configured, minimum VPI and vci=34 for NCDP clocking.
•VPI=0 and VCI=31 are used for online diagnostics.
AXSM-E OAM
•Any connection can receive E2E/OAM loopback cells up to the line rate (as long as the policing policy permits).
•If the connection is not in the loopback mode and is operating in the normal mode, then the AXSM-E card can receive up to 1,500 segment OAM loopback cells per second. Any excessive segment OAM loopback cell will dropped. This limitation applies for all the connections on a card.
•For example, if there is only one connection, then that connection can receive 1,500 segment OAM loopback cells per second. If there are 2,000 connections on an AXSM-E card and one segment OAM loopback cell per second is being pumped through on each connection, then there can only be up to 1,500 connections to receive loopback cells at any given second, and the additional 500 connections would not receive for that second.
•The limitation is 1,500 segmentOAM loopback cells is per card and not per connection, the 1,500 cps assumes an even flow rate.
CLI Configurable Access
The following notes pertain to how command access levels can be configured:
•Not all CLI commands are allowed to be changed and a command cannot be changed to CISCO_GP group access level.
•Only the switch software is allowed to generate the binary file. This file has an authentication signature which has to be validated before the file can be used. Any manual changes to the file would make the file void.
•If the binary file becomes corrupted, then the command access levels revert back to the default values during the card bring-up. To recover, repeat the installation process or retain a copy of the binary file and do cnfcli accesslevel install on that service module.
•Currently, command names are verified, but an invalid command name may be parsed and be added to the binary file. However, this invalid name would be ignored later.
•If replication to standby failed, the installation process failed.
•cnfcli accesslevel default restores all command access levels to default for the service module that this command is executed on. It does not remove the binary file and this change is not persistent. If it is executed on the active card of a redundancy pair, the standby card is not affected. When the card is reset and the binary file exists, it will configure from the binary file when it is brought up.
Controller Card Mastership Sanity Verification
Because the solution provided in this release can only detect and log invalid mastership state transitions, an outage may still occur.
Serial Bus Path Fault Isolation
The Serial Bus Fault Isolation feature only addresses isolating errors on the local cards. However, when a common error occurs on the switching fabric card, this solution does not address this. As a result, if there is a problem on the PXM card or the XM60, the fault is going to be reported against all cards that detected the symptoms of this problem.
Cell Bus Path Fault Isolation and Recovery
The following notes pertain to cell bus path faults:
•The isolation procedures can isolate the Cell Bus path involving the QE SAR that is used for polling the Serial Bus based Service Modules (e.g., AXSM, AXSM/B, AXSM-E,) and all the communication with the standby controller card and the Cell Bus Based Service Modules (e.g., FRSM, CESM). These procedures can't isolate the Cell Bus path failures involving ATMizer SAR that is used for the inter-card communication except polling, between the active controller card and the Serial Bus based Service Modules (e.g., AXSM, AXSM/B, AXSM-E).
•The isolation procedures isolate the Cell Bus path failures to the active controller card only. This means, it is determined whether the active controller card has the fault for the inter-card communication over the Cell Bus from the active controller card to the Service Modules and the standby controller card or not. It does not isolate the fault if the active controller card fails to communicate with some cards and successfully communicates with the rest on the Cell Bus.
•There should be at least 2 cards (2 Service Modules or 1 Service Module and 1 standby PXM) for the isolation procedures to be able to isolate the Cell Bus path failures to the active controller card.
•Only the failures detected by periodic polling triggers the isolation procedures. Failures reported from other sources in the system against a Service Module or the standby controller card due to the Cell Bus path failures don't initiate the isolation procedures, and which results in resetting that card against which the failure is reported, even while the active controller card is in the process of isolating the Cell Bus path failures triggered by the polling failures.
•There is no separate trap/alarm generated against the active controller card Cell Bus path when the fault is isolated to the active controller card. Only the event logs will be available that can be used during the manual investigation triggered by the card reset and/or switchover traps.
•If there is no controller card redundancy available, isolating the Cell Bus path failure to active controller card results in outage as the active controller card will be reset.
FRSM-12-T3E3
The following limitations summarize the FRSM-12-T3E3 adherence to the current Functional Specification:
Note The FRSM-12-T3E3 card does not support E3.
•CLLM will not be supported: The FRSM-12-T3E3 card can support connection level congestion through ATM EFCI. It also supports FR-ATM interworking of ECN and EFCI. Frame level congestion only happens in full line rate of sub-15 byte frames, therefore the hardware will only support Port Level Congestion Management in the Frame Relay domain.
•BERT is not supported.
•Sub-rate DS3 is not supported.
•Online and Offline Diagnostics is not supported.
•Complete core dump is not supported.
Port and Connection Limitations
The following are port and connection limitations pertaining to the new FRSM-12-T3E3 card:
Port limitations:
•4 bytes header length with Stratacom LMI is not supported
•LMI on Frame Forwarding port is not supported
•If LMI is configured, Port header length cannot be changed
Connection Limitations:
•Single ended connections can only originate from FRSM12. Single-ended connections terminating on FRSM12 are not supported.
•The command chanType cannot be modified
•If Port header length is 2 bytes, Max DLCI number is 1023
•If Port header length is 2 bytes, the restricted DLCIs are 0, 1007 and 1023
•If Port header length is 4 bytes, the restricted DLCIs are 0 and 8257535
•To add a Frame Forward connection, the port should be configured to Frame Forward type.
•For Frame Forwarding ports, the maximum configurable connection(s) is 1.
•For Frame Relay ports, the maximum configurable connection(s) is 4000.
•If the connection is in loopback, it cannot be modified
•CIR can only be 0 for UBR connections
•If CIR equals to 0, Bc should also be zero, Be and zeroCirConEir should be nonzero.
•If CIR not equals to 0, Bc should be nonzero
•If chanType is Frame Forward, chanFECNconfig should be setEFCIzero, chanCLPtoDEmap should be ignoreCLP, chanDEtoCLPmap should not be mapCLP
•If chanType is NIW or NIWReplacem chanFECNconfig should be setEFCIzero, chanCLPtoDEmap should not be setDEzero or setDEone
•If chanType is frSIW_transparent or frSIW_translate, chanCLPtoDEmap should not be ignoreCLP
Maximum connections depending on LMI type:
•Annex A/D LMI, 2 byte header, FRF 1.2 not enabled: 898 conns
•Annex A/D LMI, 2 byte header, FRF 1.2 enabled: 1000 conns (port max)
•Annex A/D LMI, 4 byte header, FRF 1.2 not enabled: 640 conns
•Annex A/D LMI, 4 byte header, FRF 1.2 enabled: 4000 conns (port max)
•Strata LMI, 2 byte header, FRF 1.2 not enabled: 560 conns
•Strata LMI, 2 byte header, FRF 1.2 enabled: 1000 conns (port max)
Disk Space Maintenance
Because the firmware doesn't audit the disk space usage and remove unused files, the disk space in C: and E: drives should be manually monitored. Manually delete any unused saved configuration files, core files and firmware files and the configuration files of the MGX-RPM-PR-256/512 and MGX-RPM-XF-512 cards to avoid a shortage of disk space required to store event logs, configuration upload files in the C: drive and the configuration of MGX-RPM-PR-256/512 and MGX-RPM-XF-512 cards in the E: drive.
Non-native Controller Front Card and PXM-HD Card
•Cisco recommends that the hard disk on the PXM1E front card and PXM-HD back card should contains at least 30% of free disk space at all times.
•When the front controller cards or the PXM-HD back cards are swapped within the same system, the system will perform a non-native card check, as a result, the controller card that attempts to come up as Active/Active may get resets twice.
•When a non-native PXM1E front card or a PXM-HD card is inserted into the standby controller slot, after the standby controller front card becomes Active/Standby, the active controller front card will copy its hard disk content over to the standby controller card. The active controller front card will not perform any automatic hard disk contents removal from neither the active nor standby controller card.
•Cisco recommended that customer regularly groom their system hard disk, that is, to remove all old files or outdated runtime and boot images resided under the following directories: C:/FW, C:/RPM, and E:/RPM. Also, any old and core files under C:/ and C:/CNF/ directories. All file removal will be perform by customer from the active pxm.
•Cisco highly recommends that the customer regular backup their saved system configuration to their local server.
•The system will keep only the two most recent copy of the saved system configuration under C:/CNF directory. Customer may use ftp protocol to ftp all the saved configuration under C:/CNF to their local server for future references. All files under C:/CNF will not replicated over to the standby controller card under any circumstances.
•The following steps are recommended to remove files on the system from the active controller card:
Step 1 Change to the directory that needs grooming.
CLI cc <directory_name>
Step 2 List the directory to identify old files that can be removed and available disk space.
CLI ll
Step 3 To remove any old files (you may also use wildcards in the filename):
CLI rm <complete_filename>
Step 4 List the directory to see if the file has been removed and disk space is available:
CLI ll
clrsmcnf Command
These notes pertain to the clrsmcnf command:
•For the clear service module configuration feature, if there is a controller card switchover before the clear service module configuration operation is complete, the clrsmcnf command needs to be re-issued to ensure that the configuration is completely cleared to avoid any incomplete cleanup.
•For the clear service module configuration feature, using the clrsmcnf command may result in discrepancy in the PNNI configuration. For example, some connections may be in the mis-match state.
•If the clrsmcnf command is given with the <all> option to clear the software version for the slot as well, then the card will go into the boot/empty state after the operation is complete.
•While using the clrsmcnf command, the card in the specified slot is not usable until the operation has successfully completed.
APS
These notes pertain to the APS feature:
•For AXSM APS, the backcard of the active card MUST be present for APS to function.
•AXSMs need the backcard of the active front card for the APS to work. This implies that AXSMs do not support the cross backcard removal, upper backcard of one AXSM and lower backcard of another AXSM.
•If you remove the upper backcard of the active front AXSM, it will trigger switching active card. At this point the APS is OK. However, if the lower backcard of the current active AXSM is removed at this time, it will not trigger switching active card since the standby card is missing one of the backcard. At this point the lower backcard APS does not work since the backcard of the active front card is missing.
•New commands dspadjlnalm and dspadjlnalmcnt are now supported on AXSM.
•Port LED lights on AXSM-E front cards indicate the receive status of physical line connected to it only when the card is in active state. For a standby AXSM-E card, the LEDs always remain green whether the lines are in LOS irrespective of which lines are Active (CSCdv68576).
Path and Connection Trace
These notes pertain to the path and connection trace features:
•Path trace is not supported on the control port.
•Path trace will not have the accurate information when there is a crankback on the connect path.
•Path and Connection trace feature in Release 4.0.00 is not compatible with the path and connection trace available with previous releases.
•Path and Connection trace supports point to point connections.
•Path and Connection trace supports MPG (multi-peer group) and SPG (single-peer group).
Simple Network Timing Protocol (SNTP)
The CWM MIB is not supported in Release 4.0.00.
Priority Routing
These notes pertain to the priority routing feature:
Prioritized reroute of SPVCs is not guaranteed, if the SPVCs originate on a signaling port. SPVCs may get routed out of order. In-order routing of SPVCs is guaranteed on non-signaling ports.
•RPM does not support configuration of routing priority. All RPM mastered SPVCs will be assigned a routing priority of 8 by the PXM.
•addcon command on SES does not have support for specifying the routing priority. All the added SPVCs are assigned a routing priority of 8. cnfcon can be used to change the routing priority of the SPVCs.
•Changing the routing priority for dax connections, will not change the priority of the associated SVCs, this is because the SPVCs will not be derouted and rerouted if just the end-point parameters are changed, and routing priority is an end-point parameter. Also since dax connections are never derouted even when the UNI port goes down and rrtcon command is not supported for dax connections, the routing priority change will never get reflected. The only way for this to get reflected is to do a dncon and upcon. The very fact that dax connections are never derouted, the effect of this limitation is voided.
•Priority routing operates in a best effort manner for the following reasons:
–Two in-order RELEASEs can still arrive out of order at the Master node, if they take two different paths.
–Under congestion scenarios we can expect RELEASEs to be transmitted out-of-order. This is because we do not want to hold up the release of other calls if we are not able to send RELEASEs on one of the interfaces, as it is congested. The calls that we are unable to release could be higher priority calls.
–Lower priority SPVCs can be routed ahead of higher priority SPVCs. This can happen if we have attempted several times to route higher priority SPVCs, but failed. To prevent starvation of lower priority SPVCs, software will start to route lower priority SPVCs and software will get to the higher priority SPVCs at a later point in time.
SPVC Interop
These notes pertain to SPVC interoperability:
•NNI SPVC Addendum Version 1.0 is not supported.
•PNNI 1.0 Addendum (Soft PVC MIB) is not supported.
•Terminating single-ended SPVCs on MSSBU switch Legacy Service Modules is not supported.
•Origination of Single ended spvcs (with -slavepersflag) from Legacy Service Modules (FRSM, CESM and RPM) is not supported.
•CC (Continuity Check) shall not be available at the slave end of a single-ended SPVC.
•Reporting AIS detection to CWM shall not be available at the slave end of a single-ended SPVC.
•tstdelay shall not be available at the slave end of a single-ended SPVC for MGX 8850. In case of SES-PNNI, the command is available from the PXM even for the slave endpoint.
•The slave end of a single-ended SPVC shall not be visible to CWM.
•If Single-ended SPVCs are originated from MSSBU switches, they can only be configured via CLI and not from CWM in the current release.
•Single-end Provisioning will not be supported for DAX connections as no value addition is seen for Interoperability.
•SPVC Statistics shall not be available for the slave endpoint of a single-ended SPVC because this endpoint is non-persistent.
•When the persistent slave endpoint of an existing SPVC connection is deleted and the master endpoint is allowed to remain, the connection may get established as a single-ended spvc connection. In this case, CWM will show the connection as "Incomplete"
•Override of SVC connections on a VPI due to an incoming SPVP request for that VPI is not supported The following override options alone are supported:
–spvcoverridesvc
–spvcoverridesvp
–spvpoverridesvp.
Preferred Route
These notes pertain to the preferred route feature:
•QoS precedence over Preferred Route does not apply to MPG network (CSCdz40310).
•Preferred route configured with higher node ID cannot be blocked (CSCdz41145, CSCdz49001).
•delpref when Preferred Route in use is allowed in Release 4 and not in Release 3
•The preferred routes can be specified only within a PNNI single peer group meaning all the nodes in the preferred route lie within the same peer group.
•All the nodes in the network should be running Release 4.0.00 software to use preferred route feature
•All the links specified in the preferred should be PNNI links
•If any of the nodes in the pnni network changes its pnni node id, then the old entry in the persistent topology database in all the nodes in the network need to be deleted. If any of the preferred routes in any of the nodes in the network contains the changed node as one of the hops, then the preferred route(s) has to be modified using the new table index (in the persistent topology database) allocated for the changed node.
•If any of the nodes in the pnni network is deleted via configuration commands from the persistent topology database, if any of the preferred routes configured at that node (where the delete command is executed) contains the deleted node as one of the hops, then the preferred route(s) has to be deleted/modified manually.
•If any of the nodes in the pnni network is removed via physical de-commissioning and if any of the nodes in the network had some preferred routes that contain the removed node as one of the hops, then the preferred route(s) has to be deleted/modified manually.
•Due to differences in physical port numbering, non-MSSBU nodes can only be the terminating nodes in a preferred route.
•When a connection is routed on a route other than its preferred route and if the preferred route becomes available, the connection would not be automatically de-routed to route back to its preferred route. The user has to de-route/re-route using configuration commands. (optrte, rrtcon, dncon/upcon etc)
Persistent Topology
These notes pertain to the persistent topology feature:
•In a mixed network of pre-Release 4.0.00 and 4.0.00 or later nodes, only the node name and the node id will be shown for a pre-Release 4.0.00 node in the topo DB. This is because the feature is not present in pre-Release 4.0.00 nodes.
•If a peer group is made up of physical nodes with pre-Release 4.0.00 release logical nodes, then the info for the logical node will be stored in the Topo DB, because there is no way to distinguish between physical nodes and pre-Release 4.0.00 release logical nodes. Logical nodes with Release 4.0.00 or later SW release will not be stored in the Topo DB.
•To delete a node info entry from the Topo DB, first remove the node itself from the network, either by disconnecting the cables, or downing all the links between that node and the network. Wait for an hour. Then, delete that node from the topo DB. This is done because, even if a node is removed from the topo DB of all nodes in the peer group, its PTSEs will still be stored in the other nodes, until they are flushed from those nodes. This would happen within an hour's time, but it is configurable as a PNNI timer value. If the node is deleted from the Topo DB within that hour's time, and the node does switchcc/reboot, then it's possible that the node info for that deleted node will be added back into the topo db.
•When the node id of a node is changed, the old node id is added back into the Topo DB as a new node entry. In addition, the old node id will still be stored in the topo DB of all the other nodes in the PG. In order to delete this entry, wait for an hour so that the PTSEs with the old node id is flushed from the DB of all the nodes in the PG, and then delete the info of the old node id from the topo DB.
•It is possible that the gateway nodes are not in sync in a peer group, and this could happen in many situations. For example, a gateway node is added in a peer group, then a node is deleted from the PG, and another gateway node is configured, then the info for the deleted node would not be in the second gateway node. Another example is that a node is deleted from one gateway node, but not in another gateway node.
•When deleting a node from the PG, the node info must be deleted from all the nodes in that PG, even the non-gateway-node nodes. Otherwise, the node info for that deleted node will still be in the non-gateway-node nodes. This could cause inconsistencies later if this node is configured to be a gateway node.
Manual Clocking
These notes pertain to manual clocking:
•AUSM can support only one clock. If a second clock is configured on the same AUSM card AUSM will nack us. When the second clock is naked no warning or message is given by the CLI. The NAK can only be found out by looking through the logs. The second clock configured on the AUSM will not be reflected in the clocking database
•If the line carrying the primary or the secondary clock source goes in alarm and a switchcc is done on the switch the clock configuration for the line in alarm will be wiped out. The clock configuration will also be wiped out if any card is rebooted when the clocking line is in alarm. This only applies to AXSM.
•NO clock sources supported on FRSM. If a clock source is configured on FRSM it will not be reflected in our database.
•When resetcd is invoked on a service module, the primary and secondary (if configured) clock sources will be recommitted even though the primary or secondary clock source is not a port on the service module that was reset. Recommitted means that the primary and secondary will get requalified and the node will temporarily latch onto the internal oscillator, After the clock is requalified, the node will lock onto the primary clock source once again.
AXSM Cards
If ER stamping is used, the rate interval does not provide sufficient accuracy to be completely effective. As a result, when an AXSM card is supporting a PNNI link which is congested with mixed CBR/ABR traffic, cells will be dropped. This Conditions only occurs when ER stamping is enabled and CI is disabled on an AXSM PNNI link, along with CBR/ABR traffic running so as cause congestion on the link.
We recommend that the CI/EFCI mechanism be used for rate feedback rather than the ER stamping mechanism, especially if CBR/ABR traffic is expected. (CSCdw63829)
AXSM-XG Hardware Limitation
The IR/LR/XLR SFP modules will need a 10 db attenuator when connected with short cables. Otherwise we will be exceeding the specification for receiver sensitivity on the Rx.
ATM Multicast
The recommended configuration for MGX 8950 with ATM multicast application is as follows:
•MGX 8950 system loaded with AXSM/Bs without any AXSM-XG cards in the system
•MGX 8950 system loaded with all AXSM-XG based cards without AXSM/Bs in the system.
•The MGX 8950 system having a mix of AXSM-XG based card and AXSM/Bs is not a recommended configuration for ATM Multicast application. The limitation is due to the behavior of backplane serial buses in the system. The suggested workaround:
–In order for the MGX 8950 system with AXSM-XG based card and AXSM/B to be present in the network supporting ATM Multicast the PNNI Node configuration can be made as branching restricted. cnfpnni-node 1 -branchingRestricted on
RPM-PR and RPM-XF Limitations
For Release 4.0.00, Route Processor Module (RPM) cards have their own release notes. For details on RPM cards, refer to the "Release Notes for Cisco MGX Route Processor Module (RPM/B and RPM-PR) for MGX Release 1.2.20 and MGX Release 4.0.00" or the "Release Notes for Cisco MGX Route Processor Module (RPM-XF) for MGX 8850 (PXM45) Release 4.0.00". These release notes are available online at http://www.cisco.com/univercd/cc/td/doc/product/wanbu/index.htm. They are found under the switch name (for example, MGX 8850 (PXM45), Release 4, Route Processor Module, Release Notes).
Restrictions
AXSM-32-T1E1-E and PXM1E-16-T1E1
PNNI requires SCR=453 cells/sec and PCR=969 cells/sec for the control connection.
SSCOP requires of SCR=126 cells/sec and PCR= 2000 cells/sec.
AXSM Model B Restrictions
These restrictions apply to AXSM model B cards:
•The enableaxsmbaps command is a PXM CLI command required to turn on additional APS features on AXSM/B cards in Releases 3.0.x and up. By issuing this command, the card operating mode becomes AXSM Op B. This command is required only while upgrading configured cards with Release 3.0.x images. If the AXSM/B cards do not have any configuration and are upgraded with Release 3.0.x, then the card operating mode would be made as AXSM Op B and it is not required to issued the enableaxsmbaps command.
The command has the following syntax:
• enableaxsmbaps <primary | secondary slot>
•The enableaxsmbaps command should be given after the completion of upgrading to Release 3.0.x. The following requirements are needed to change the card operating mode to AXSM Op B:
•For redundant cards, both the cards should be AXSM/B cards and the image on both cards should be Release 3.0.x and up.
•For non-redundant cards, the card should be an AXSM/B and the image should be Release 3.0.x and up.
Formatting Disks
The hard disks should not be formatted with the Release 4.0.00 backup boot or runtime firmware. The Release 4.0.00 firmware initializes the disks with DOS File System Version 2.0 where as the earlier 2.x releases use DOS File System Version 1.0. As a result, if the hard disks are formatted with Release 3.0.00 firmware, those disks will become unusable in nodes running Release 2.x firmware. Since, Release 4.0.00 firmware is backward compatible, it can use hard disks with DOS File System Version 1.0.
Saving Configurations
The C disk drive should not be used for saving multiple older configurations, images, and core dumps. The disk space on this drive is needed to save event logs and configurations, and the logs and configurations will not be correctly saved if there is inadequate disk space.
•Save on all active PXM45 and PXM1E cards.
Other Limitations and Restrictions
Here are additional notes that pertain to Release 4.0.00:
•When configuring virtual interfaces (i.e. VUNI, VNNI, EVUNI, EVNNI), the physical interface must be of all one ATM header type, either UNI or NNI. Keep in mind that the signaling that is applied to a virtual port is independent of the actual virtual port ATM header. The only limit will be that the VPI value must be within the UNI ATM header limitations.
•Bulk Status Enquiry is a proprietary signaling message used to check whether connections across peer nodes are intact. It is triggered automatically upon PXM switchover as well as in other scenarios like SSCOP link establishment. Though Bulk Status Enquiry will not work with Release 2.1 when the peer node is running release 3.0/4.0, there is an automatic fall back mechanism to standards specific "Normal Status Enquiry" procedure in case the bulk procedure fails. Hence, there should be no loss of functionality as a result of this limitation.
•If command clrchancnt is executed while a dspchancnt command is currently active then the data displayed will be incorrect. Restarting the dspchancnt after the previous one has completed will display correct data.
•Configuration required for preventing CLI lockout on PXM45(A) based via nodes: When a PXM45(A) based node is a via node for PXM45/C based end nodes, a normal deroute followed by a reroute will result in a CLI lockout on the PXM45(A) node. If there are permanently failed connections originating on the PXM45/C end nodes, then the CLI lockout will be extensive. To circumvent this situation, configure the following on the PXM45/C nodes which are adjacent to the PXM45(A) node: cnfnodalcongth -connpendhi 950 -connpendlo 750 Note that this is same as the recommended threshold for PXM45/B. This will ensure that the PXM45/C based nodes do not pump SETUPs towards the PXM45(A) node at a high rate. (CSCdz90598)

Clearing the Configuration on Redundant PXM45 and PXM1E Cards
•Due to checks to prevent an inserted card from affecting the system, an additional step may be required when inserting two nonnative PXM45 (or PXM1E) cards in a shelf. Insert the first PXM45, use the clrallcnf command, and allow this to become active before inserting the second PXM45 (or PXM1E).
•After a clrallcnf, the user needs to explicitly clean up stale SCT files (refer to anomaly CSCdw80282).
Limitations and Restrictions for 2.1.x
This section is extracted from the MGX 2.1.80 release notes. It describes the following issues for Releases 2.1.60 through 2.1.80:
•General limitations, restrictions, and notes
•APS management information and open issues
•Clearing the configuration on redundant PXM45/B cards
General Limitations, Restrictions, and Notes
The following limitations and restrictions apply to Release 2.1.x and other releases:
•After switchcc, there was some competition for 8k buffer resources. Since dbSync could not allocate the buffer to handle its file sync between Active and Standby, the "going to be" Standby card was reset again then came up later.
In 2.1 and earlier, dbSync allocates its resources from the same LOW priority pool as many other applications; therefore, dbSync might fail should the resource in this pool be used up.
In 3.0 and later, there was an enhancement to let critical tasks (dbSync, syncRam.) allocate its resources with a HIGH priority option. This means these tasks can get its resources from both LOW and HIGH priority pool and prevent this problem from happening (CSCdz84282).
•For a graceful upgrade, you must upgrade from version 2.1.80, or 2.0.16 or below to 2.1.80 to 3.0.00.
•Presently, the PXM CLI allows for provisioning of a PNNI controller (controller id 2) on any slot in the chassis, but for this release, such provisioning should be restricted to slot 7 only.
•APS is not supported on AXSM-1-2488/B.
•Of 192 PNNI interfaces, up to 100 interfaces can be signaling ports. The other 92 interfaces should be non-signaling ports, such as non self-supporting ports.
•AXSM-1-2488 and AXSM-1-2488/B cards do not have a policing function enabled.
•The front card hardware (mother board/daughter board) for each card type can support up to two back cards. But in Release 2.1.80, only one AXSM-E back card (i.e., half the port capacity available in hardware) is supported by software. The full port capacity will be supported with a future software release. No hardware changes will be required.
•In Multiple Peer Group (MPG) mode, when one switches over to the standby on a PGL node with 3 levels, it can take several minutes on the standby card for this PGL to come up and the SVC based RCC to setup. This is normal behavior, because PNNI doesn't support hot redundancy. So on switch over, the entire PNNI database has to be rebuilt. (It is like a reboot for PNNI, even though the active calls are not affected.)
•Trace information captured in the error logs of non PXM slots (seen with dsperr -sl <slotnum>) will not translate addresses in the trace to correct symbolic names. Such files with trace data need to be moved off the system using FTP and forwarded to TAC and engineering.
•Support for 3 controllers only (1 for PNNI and 2 for LSC). Controller ID 2 is reserved for a PNNI controller; IDs 3-20 are available for LSC controllers.
•Partition ID 1 is reserved for PNNI.
•The maximum number of logical interfaces (physical trunks, virtual trunks, logical ports) supported in this release with PXM45 cards is 99 and PXM45/B cards is 192.
•If an active AXSM card is stuck in the active INIT state, the standby PXM will not go to the standby Ready state until the active AXSM goes to a steady state. Steady states are: Active Ready, Failed, Mismatch, Empty, Empty Reserved, Standby Ready. With redundancy configured, if a standby AXSM card is stuck in a standby init state, with an active Active AXSM already in a Active Ready state, the standby PXM will go to the standby Ready state without any delay. If both AXSMs in the redundancy pair are not in a steady state, then the standby PXM will not go to the standby Ready state until one or both of the 2 AXSM cards are in the active Ready state.
•If the destination address is reachable for both an IISP and a PNNI link from the same node, ABR connections will not route. The current routing algorithm will always choose IISP links over PNNI links because it is local. Since IISP does not support ABR connections, the connection setup will fail.
•In this release, a Service Class Template (SCT) can be changed with connections present. However, if the change affects services in use, the connections will be rerouted.
•When CWM is used to manage the network, the IP address 10.0.x.x cannot be used as the LAN address (lnPci) for the switch.
•If there are MGX-RPM-PR-256/512 card(s) in the node, after clrallcnf, the standby controller card takes longer to come up. The more MGX-RPM-PR-256/512 cards in the node, the longer the standby controller takes to come up. This also happens when the standby controller card is coming up, and MGX-RPM-PR-256/512 cards are inserted into slots that were not previously used for MGX-RPM-PR-256/512 cards.
Limitations for rteopt via parallel links
The following are limitations for rteopt via parallel link.
link 1 . . . . . .. . . .. . . . .link 2
Node A ------------- Node B -------------- Node C
fwd & bwd aw= 500 fwd & bwd aw= 1000
-------------
link 3 fwd & bwd aw = 2000
Configuration:
•link 1 has forward and backward admin weight set to 500 (via cnfpnni-intf)
•link 2 has forward and backward admin weight set to 1000
•link 3 has forward and backward admin weight set to 2000
•SPVC connection is routed from Node A to Node C (Master endpoint is at Node A) via link 1 and link 2
Scenario 1
Link 2 is down (e.g., via dnpnport), connections are re-routed right away but Node A hasn't had that info updated in the routing tables.
So SPVC on Node A will have routing cost = 2*500 + 2*1000 = 3000, but since link 2 is down, Node B will choose link 3. But the routing cost on Node A SPVC is still 3000 as it did the calculation during the route search.
Now if link 2 is up, if you do rteopt on Node A, it gets the new route, the new path selected has a cost of 3000.
Since spvc has 3000, it doesn't re-route through link 2.
Scenario 2
Instead of link 2 down, if there is a crankback on link 2, the same result stated above will happen.
Scenario 3 (for CBR and VBR)
Link selection is set as maxavcr or maxcr or random on node B (via cnfpnni-selection) If link 2 has less bandwidth than link 3, and the link selection criteria at Node B is set to maxavcr, Node A will still put the cost as 3000 with least aw calculation, but Node B will choose link 3 (even though it is costlier) because it has more bandwidth.
Scenario 4 (for ABR and UBR)
Link selection doesn't apply to ABR and UBR. (via cnfpnni-selection. This is exactly the same as Scenario 3 as ABR and UBR follow load balancing on parallel links instead of choosing the minaw link.
Scenario 5 (for all types of service categories)
After call setup, if the admin weight is increased on the link on which the call is routed, the routing cost calculated during the call setup will not get changed. So if a rteopt is done after increasing admin weights on the existing links on the connection path, the connections will not get optimized to take the newer path.
Workaround
If you dnpnport on link 2 (connections will be routed via link 3), after uppnport on link 2, then use cnfpnni-intf to change the existing admin weight on link 2 to lesser value, e.g., 800 (from 1000).
So when optrte is executed at Node A, routing cost will be = 2*500 + 800(fwd) + 1000 (bwd) = 2800 for the new route of link 2.
Since all SPVC connections have 3000 as the routing cost, connections will be rerouted on link 2.
Important Notes
This section provides general notes that apply to this release, and covers some procedures that are not yet in the manuals.
•You must use the SCT files released with 2.1.80 (number 2 and 3, which were included in version 2.0.13 are similar to number 2 and 3 for 2.1.80) for the Control VC feature. If you are using the MPLS feature, then you will need to change to SCT 4 or 5, which were released with version 2.1.00.
•By default, 2000 cps and 543 cps will be reserved for SSCOP and PNNI Signalling VC respectively, even when you disable SSCOP and PNNI. These values are configurable by the cnfpnctlvc command.
•Do not execute the delcontroller command when connections/ports still exists. The impact of executing delcontroller with connections is that the connections cannot be recovered until the controller is re-added using addcontroller and the AXSM cards or the entire node has to be reset (otherwise ports remain in the provisioning state). There is now a warning to the user of the impact of the command when there are existing connections/ports.
•Analysis of the code has identified a situation which has a low probability of occurring and in fact has not been encountered in any test scenarios to date. This caution and associated workaround is provided as a precautionary measure. When the link bandwidth for SPVC connections is reaching full capacity, making minimal bandwidth available for new SPVC connections, a Conditions can be encountered where the initial software check believes there is sufficient bandwidth for the new SPVC connection; however, the final software confirmation for available bandwidth may be rejected because there is no bandwidth available. If this problem occurs, the system will recover when the PNNI updates are refreshed. (This will happen at the default time of 30 minutes.) The user can recover from this problem by making the Administrative weight of that link very high to avoid that link from being used.
•When the switch cannot automatically resolve nativity check conflicts, you can force a configuration rebuild from a specific hard disk by establishing a console port session through the corresponding PXM-UI-S3 card and issuing the shmRecoverIgRbldDisk command. This command ignores the nativity check and configures the entire switch according to the configuration on the hard disk.
•PNNI default min VCI is 35 unless changed explicitly. The reason for the default is to reserve VCI=32-34 for other control purposes (e.g., MPLS and NCDP). For users who would like to add MPLS controller in future releases of MGX 8850, it is highly recommend to set the min-vci value to be 35 or more for all partitions on the port where the MPLS partition will be added. By doing so, the TDP signaling vc for MPLS will be established automatically on 0/32. MinVPI is not negotiated by ILMI, so the user should set this parameter same on both nodes.
•In Multiple Peer Group (MPG) mode, when one switches over to the standby on a PGL node with 3 levels, it can take several minutes on the standby card for this PGL to come up and the SVC based RCC to setup. This is normal behavior, because PNNI doesn't support hot redundancy. So on switch over, the entire PNNI database has to be rebuilt. (It is like a reboot for PNNI even though the active calls are not affected.)
APS Management Information
The following tips apply to the use of the dspapsbkplane command and the APS connector, which is sometimes called a backplane. The APS connector must be installed to enable intercard APS.
The APS commands dspapsln, dspapslns, switchapsln, and dspapsbkplane were modified in release 2.1.70.
Note Commands dspadjlnalm and dspadjlnalmcnt are available since Release 3.0.00. The command dspadjlnalmcnt is supported on AXSM-E and AXSM/B.
The APS command dspadjlnalm was new to release 2.1.70.
Refer to the following command references for details about commands mentioned in these release notes:
•The Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830 Command Reference, Release 4, part OL-3846-01, available online at http://www.cisco.com/univercd/cc/td/doc/product/wanbu/8850px45/rel4/cmdref/index.htm
•The Cisco ATM Services (AXSM) Software Configuration Guide and Command Reference for MGX Switches, Release 4, part OL-3852-01, available online at http://www.cisco.com/univercd/cc/td/doc/product/wanbu/8850px45/rel4/axsm/index.htm
Note The issues in this section are seen only in Operational mode 1+1, bi-directional, Rev/non-Rev. If at least one side is configured as 1+1 unidirectional, these problems do not occur.
The following are some open issues in this release:
•Reset of active AXSM, removal of active AXSM, or AXSM switchover may cause the lines behind that card to be in a LOS status for 20 to 30 ms. If these lines were active at the time, some additional APS switch will occur; and the corresponding lines at the far-end will be in SF alarms before the standby AXSM is coming up. The momentary loss of signal is due to the hardware limitation; no other workaround is available.
•For AXSM/A hardware only: If multiple active lines are removed at the same time, one line may not switchover.
–To recover, either perform lockout of Protection line and Clear from the far end or perform delete APS for the line, then add the APS line back.
Preparing for Intercard APS
The following components are required for intercard APS:
•two front cards.
•two back cards for every pair of slots hosting APS lines. All lines on cards used for intercard APS must operate in APS pairs or use Y cables.
•an APS connector installed between the two back cards for every pair of slots hosting APS lines, except for AXSM-XG cards in an MGX 8950 chassis.
Use the dspapsbkplane command on both the standby and active card to verify that the APS connector is plugged in properly. The following example shows the results displayed by the dspapsbkplane command when the APS connector is in place:
M8xx0_NY.1.AXSM.a > dspapsbkplaneLine-ID Primary Card Signal Status Secondary Card Signal StatusSlot #1 Slot #21.1 PRESENT PRESENT1.2 PRESENT ABSENT2.1 PRESENT ABSENT2.2 PRESENT ABSENTRemote Front Card : PRESENTTop Back Card : ENGAGEDBottom Back Card : ENGAGEDThe following example shows the results displayed by the dspapsbkplane command when the APS connector is not place:
M8xx0_LA.1.AXSM.a > dspapsbkplaneLine-ID Primary Card Signal Status Secondary Card Signal StatusSlot #1 Slot #21.1 PRESENT ABSENT1.2 ABSENT ABSENT2.1 PRESENT ABSENT2.2 ABSENT ABSENTRemote Front Card : ABSENTTop Back Card : ENGAGEDBottom Back Card : NOT-ENGAGED
Note The dspapsbkplane command should be used only when the standby card is in the Ready state. When the standby card is booting or fails, intercard APS cannot work properly and this command displays "NOT ENGAGED."
If the dspapsbkplane command displays the message "APS Line Pair does not exist," suspect that the APS is not configured on a line.
If the dspapsbkplane command shows different values for each of the two cards, suspect that the APS connector is seated properly on one card but not on the other.
The APS connector status is the same for all lines in a single bay because the APS connector interconnects two back cards within the same bay. You need to enter the dspapsbkplane command only once to display the APS connector status for both upper and lower bays.
Enter the dspapslns command to verify APS configuration. If the working and protection lines show OK, both lines are receiving signals.
Managing Intercard APS Lines
In AXSM and AXSM/B intercard APS, either front card can be active, and can be connected to either APS line through the APS connector joining the two back cards. The following process describes how intercard APS communication works:
Step 1 The signal leaves the front card at the remote end of the line. (See Figure 1 and Figure 2.)
Step 2 The signal passes through the APS connector and both back card transmit ports at the remote end of the line. (See Figure 1 and Figure 2.)
Step 3 The signal travels through both communication lines to the receive ports on both back cards at the local end. (See Figure 1 and Figure 2.)
Step 4 The active front card processes the signal that is received on the active line. (See Figure 1 and Figure 2.)
Step 5 The standby card monitors only the status of the standby line. (See Figure 1 and Figure 2.)
Step 6 If necessary, the signal passes through the APS connector to the front card. (See Figure 2.)
Note For AXSM, the front card monitors only one of the receive lines. For AXSM/B, the front card monitors both the receive lines.
Figure 1 shows an example of how this process operates in a standard APS configuration, where the primary card monitors the working line and the secondary card monitors the protection line.
Figure 2 shows an example of how the APS communication process operates in a crossed APS configuration, where the secondary card monitors the working line that is attached to the primary card, and the primary card monitors the protection line that is connected to the secondary card.
Figure 1
Standard APS Configuration
Figure 2
Crossed APS Configuration
Line failures are always detected at the receive end of the line. This is where a switchover occurs when a failure is detected. Two different types of switchovers can occur, depending on whether the APS was configured as unidirectional or bidirectional in the cnfapsln command:
•When a failure occurs on a line configured for unidirectional switching, the switch changes lines at the receive end only. A switchover is not necessary at the transmit end because the transmitting back cards send signals on both lines in the 1 +1 APS configuration.
•When a failure occurs on a line configured for bidirectional switching, a switchover occurs at both ends of the line.
If the status of the standby line is good, a switchover from the failed active line to the standby is automatic.
Enter the cnfapsln command to enable an automatic switchover back to the working line after it recovers from a failure, as shown in the following example:
M8xx0_LA.1.AXSM.a > cnfapsln -w 1.1.1 -rv 2Table 16 describes the configurable parameters for the cnfapsln command.
If you want to manually switch from one line to another, enter the switchapsln <bay> <line> <switchOption> command, as shown in the following example:
M8xx0_LA.1.AXSM.a > switchapsln 1 1 6Manual line switch from protection to working succeeded on line 1.1.1Table 17 describes the configurable parameters for the cnfapsln command.
Enter the dspapslns command to verify that the active line switched over from the protection line to the working line, as shown in the following example:
M8xx0_LA.1.AXSM.a > dspapslnsWorking Prot. Conf Oper Active WLine PLine WTR Revt Conf Oper LastUserIndex Index Arch Arch Line State State (min) Dir Dir SwitchReq------- ----- ---- ----- ------ ----- ----- ----- ---- ---- ---- ----------1.1.1 2.1.1 1+1 1+1 working OK OK 5 Yes bi bi ManualP->WTroubleshooting APS Lines
Port light behavior changed in Release 3.0.00 as follows:
Port lights on AXSM /B front cards indicate the receive status of APS lines. The active front card always displays the status of the active line. The standby card always displays the status of the inactive line. If only one APS line fails, the line failure LED is always displayed on the standby front card.
Port lights on AXSMB front cards indicate the receive status of the Physical Line connected to it. For example, when APS is configured for working line as 5.1.3 and protection line as 6.1.3, regardless of which card is active, port LED on card 5 will show the receive status of 5.1.3 and card 6 will show the receive status of 6.1.3.
Note The remainder of this section is the same as for Release 2.1.80 unless otherwise noted as updated for Release 3.0.00.
Caution When the active front card and the active line are in different slots and the inactive line has failed, it is easy to incorrectly identify the failed line as the line in the standby slot. To avoid disrupting traffic through the active line, verify which physical line is at fault before disconnecting the suspect line.
If the active line fails and the standby line is not available, the switch reports a critical alarm.
If the active line fails and the standby line takes over, the former standby line becomes the new active line, and the switch reports a major alarm.
If an AXSM/A front card fails, APS communication between the redundant front cards fails. This can result in one of the following situations:
•If both APS lines were working before the failure, an APS line failure causes a switchover to the protection line
•If either APS line failed prior to a front card failure, a failure on the active line does not cause a switchover to the other line. Because the standby front card failed, it cannot monitor the standby line and report when the line has recovered. This means that the active card cannot use the standby line until the standby front card is replaced and the line problem corrected.
Use the following procedure to troubleshoot APS lines.
Step 1 Enter the dsplns command to determine if the line in alarm is an APS line. The dsplns command shows which lines are enabled for APS:
M8xx0_.1.AXSM.a > dsplnsMedium MediumSonet Line Line Line Frame Line Line Alarm APSLine State Type Lpbk Scramble Coding Type State Enabled----- ----- ------------ ------ -------- ------ ------- ----- --------1.1 Up sonetSts12c NoLoop Enable Other ShortSMF Clear Enable1.2 Up sonetSts12c NoLoop Enable Other ShortSMF Clear Disable2.1 Up sonetSts12c NoLoop Enable Other ShortSMF Clear Disable2.2 Up sonetSts12c NoLoop Enable Other ShortSMF Clear DisableIf the line in alarm is an APS line, and has always functioned properly as an APS line, proceed to Step 2.
If the line in alarm has never functioned properly as an APS line, verify that the following are true:
•redundant front and back cards are in the appropriate bays and are installed at both ends of the line.
•cable is properly connected to both ends of the line.
•enter the dspapsbkplane command to verify that the APS connector is installed properly at both ends of the line.
Step 2 Enter the dspapslns command at both ends of the communication line to determine whether one or both lines in an APS pair are bad. Use Table 18 to help you determine which APS line is not functioning properly.
Note Table 18 is updated for Release 3.0.00.

If one or both lines appear to be bad, determine whether the working or protection line is in alarm. Troubleshoot and correct the standby line first. Replace the components along the signal path until the problem is resolved.
•If the dspapslns command at either end of the line indicates a front or back card problem, resolve that problem first. (See Table 19 to troubleshoot card problems).
•If the dspapslns command shows a signal failure on the standby line, replace that line.
•If the standby line is still down, replace the cards along the signal path.

Upgrade Limitations
When connections are built on an AXSM_B card with software version 2.1(80) and the card is replaced with a regular AXSM, the connections remain OK. When this node is upgraded to Release 3.0.10, the card will go into a mismatch state indicating that the reserved card is an AXSM_B. See anomaly CSCdz72564 for details.
Frame Discard
Note An important caveat exists for virtual path connections (VPCs) that were added with frame discard enabled before version 3.0.23 or 4.0.10. The switch lets you enable frame discard on a VPC, even though hardware does not support it. If a VPC with frame discard enabled already existed on the node when you upgrade to release 3.0.23, 4.0.10, or later, you cannot subsequently modify the VPC unless you delete it, then re-add it with frame discard disabled. To avoid the need to delete a VPC, disable frame discard on any such VPCs before you upgrade to MGX releases 3.0.23, 4.0.10, or later.
The order of software releases was as follows:
•MGX 4.0.00 April 2003
