Release Notes for Cisco ONS 15327
Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.

Maintenance and Administration
Caution VxWorks is intended for qualified Cisco personnel only. Customer use of VxWorks is not recommended, nor is it supported by Cisco's Technical Assistance Center. Inappropriate use of VxWorks commands can have a negative and service affecting impact on your network. Please consult the troubleshooting guide for your release and platform for appropriate troubleshooting procedures. To exit without logging in, enter a Control-D (hold down the Control and D keys at the same time) at the Username prompt. To exit after logging in, type "logout" at the VxWorks shell prompt.
A DBOSYNC alarm might be raised after circuit deletion, then creation, and subsequent (within 15 seconds) fiber pull on the same circuit. To recover from this, write the database once again with any provisioning change. This issue is resolved in Release 5.0.
When you perform a database restore initiated while the database is being saved, a DBOSYNC or BKUPMEMP alarm may be raised, accompanied by a silent restore failure. To avoid this issue, ensure no provisioning was changed within past 2 minutes before initiating a restore. This issue is resolved in Release 4.6.
The CTC card level provisioning pane allows a different range of values for the PSC-W, PSC-S, and PSC-R thresholds from the range allowed in the defaults provisioning window. At the CTC card view for an OC-192 card, CTC will allow any values for the PSC-W, PSC-S, and PSC-R. When provisioning these same values using the CTC node view defaults pane, the range is restricted from 0 to 600. This issue is resolved in Release 4.6.
Rarely, in the detailed circuit view for some VT circuits, a question mark may appear in the center of a port graphic. Ignore the question mark: it would indicate a problem with path trace functionality, but VT circuits do not have that functionality. This issue is resolved in Release 4.6.
If a user is logged into CTC as a superuser (or other higher level security type), and then another superuser changes the first user's security level to "retrieve" (or another lower level security type) without first logging the user out, the lower level user is then still able to perform some actions authorized only for the original login security level. For example, a "provisioning" level user demoted to "retrieve" level in this manner can still provision and edit MS-SPRings (BLSRs) while logged into the current session, though the same user may no longer provision DCCs. To ensure that a user's level is changed completely, the superuser must log the user out prior to changing the security level. This issue is resolved in Release 4.6.
In the Maintenance > Cross Connect Resource Pane, the VT matrix port detail is inconsistent with the general VT matrix data. This can occur when a 1+1 protection scheme is in place. To avoid confusion, note that the VT matrix data counts the VTs for both the working and protect card, while the detail data counts the VTs only for the working card. This issue is resolved in Release 4.6.
CVs are not positively adjusted after exiting a UAS state. When a transition has been made from counting UAS, at least 10 seconds of non-SES must be counted to exit UAS. When this event occurs, Telcordia GR-253 specifies that CVs that occurred during this time be counted, but they are not. There are no plans to resolve this issue at this time.
A change of the alarm profile while alarms are present on a DS3 card is not correctly applied. The behavior is specific to DS3 ports on an ONS 15327 node. This issue is resolved in Release 5.0.
A node connection might fail during bulk circuit creation, causing the circuit creation to also fail. For example, this has been seen while creating 224 VT 1.5 protected circuits, on a path protection consisting of eight ONS 15327 nodes. If you experience a bulk circuit creation failure of this type, cancel the circuit creation batch, then delete any incomplete circuits. Restart the batch from the last successful circuit. This issue will not be resolved.
CTC is unable to communicate with an ONS 15327 that is connected via an Ethernet craft port. CTC does, however, communicate over an SDCC link with an ONS 15327 that is Ethernet connected, yielding a slow connection. This situation occurs when multiple ONS 15327s are on a single Ethernet segment and the nodes have different values for any of the following features:
•Enable OSPF on the LAN
•Craft Access Only
When any of these features are enabled, the proxy ARP service on the node is also disabled. The ONS 15327 proxy ARP service assumes that all nodes are participating in the service.
This situation can also occur immediately after the aforementioned features are enabled. Other hosts on the Ethernet segment (for example, the subnet router) may retain incorrect ARP settings for the ONS 15327s.
To avoid this issue, all nodes on the same Ethernet segment must have the same values for Enable OSPF on the LAN, Enable Firewall, and Craft Access Only. If any of these values have changed recently, it may be necessary to allow connected hosts (such as the subnet router) to expire their ARP entries.
You can avoid waiting for the ARP entries to expire on their own by removing the SDCC links from the affected ONS 15327 nodes. This will disconnect them for the purposes of the proxy ARP service and the nodes should become directly accessible over the Ethernet. Network settings on the nodes can then be provisioned as desired, after which the SDCC can be restored.
This issue will not be resolved.
When the topology host is connected to multiple OSPF areas, but CTC is launched on a node that is connected to fewer areas, the topology host appears in CTC, and all nodes appear in the network view, but some nodes remain disconnected. This can occur when the CTC host does not have routing information to connect to the disconnected nodes. (This can happen, for example, if automatic host detection was used to connect the CTC workstation to the initial node.)
CTC will be able to contact the topology host to learn about all the nodes in all the OSPF areas, but will be unable to contact any nodes that are not in the OSPF areas used by the launch node. Therefore, some nodes will remain disconnected in the CTC network view.
To work around this issue, if no firewall enabled, then the network configuration of the CTC host can be changed to allow CTC to see all nodes in the network. The launch node must be on its own subnet to prevent network partitioning, and craft access must not be enabled. The CTC host must be provisioned with an address on the same subnet as the initial node (but this address must not conflict with any other node in the network), and with the default gateway of the initial node. CTC will now be able to contact all nodes in the network.
If a firewall is enabled on any node in the network, then CTC will be unable to contact nodes outside of the initial OSPF areas. This issue will not be resolved.
On Cisco ONS 15327 platforms equipped with XTC cross-connect cards, Ethernet traffic may be lost during a BLSR protection switch, with no accompanying alarm or condition raised. Possible affected circuits will be between Ethernet cards (E100T-4) built over Protection Channel Access (PCA) bandwidth on BLSR spans. When BLSR issues the switch, the PCA bandwidth is preempted. Since there is no longer a connection between the ends of the Ethernet circuit, traffic is lost. Further, in nodes equipped with XTC cards, the E100T-4 cards do not raise an alarm or condition in CTC. This issue will not be resolved.
A software revert from Release 3.3 or 3.4 to 1.0.1 or 1.0.2 can cause a PDI-P alarm on intermediate nodes of a DS3 circuit after an XTC switch on the node terminating this circuit. This can occur when, after you revert all the nodes of a path protection from Release 3.3-4 to Release 1.0.1-2, then perform an XTC side switch on the node terminating the DS3 circuit. If this occurs, remove the active XTC (software reset will not work) on the node terminating the DS3 circuit. This issue is resolved for Releases 3.3 and later, but will still occur when you revert from one of these releases to Release 1.0.1-2. The issue cannot be resolved for these earlier releases.
Upgrades from Release 1.0
If you wish to upgrade from Release 1.0 to Release 4.1.x, you must first upgrade to maintenance Release 1.0.2. If you are already running maintenance Release 1.0.1 or better, you do not have to perform the intermediate upgrade.
You cannot delete the standby XTC once it is removed. If you have two XTC cards and then decide to operate with only one, you will get a standing minor alarm. The alarm cannot be removed by CTC. The XTC is a combo card, combining the functionality of the ONS 15454 TCC+, cross connect, DS1 and DS3 cards, with a protection group automatically provisioned. On the ONS 15454, similar behavior occurs for the TCC+ card. The cross connect card for the ONS 15454 can only be deleted if there are no circuits provisioned. DS1 and DS3 cards can only be deleted if they are not in a protection group. It is not known at this time when or if this issue will be resolved.
DS1 and DS3 PMs on the XTC card are not marked Invalid for node time changes greater than ten seconds. Telcordia GR-253 requires that current PMs be marked invalid when the time change is over ten seconds. This issue is resolved in Release 4.6.
DS1 and DS3 PMs on the XTC card are not marked Invalid when the node time changes to midnight. The current interval should be changed to a yellow color to indicate that this interval is invalid once the node time changes. This issue is resolved in Release 4.6.
On an ONS 15327 the 1 day current interval for DS1 and DS3 PMs does not scroll over to the "Prev" interval if DST (Daylight Savings Time) is enabled on the node, the time is changed, and the date rolls over. This issue is resolved in Release 4.6.
Under the conditions listed below, the DS1 card does not raise Loss of Frame for a Mismatched Frame Format. This can happen when you change from the correct frame format to an incorrect frame format, where the correct format is Unframed and the incorrect format is D4, and you switch from the incorrect, to correct, and back to the incorrect format. This issue is resolved in Release 5.0.
A DS1 AINS circuit might change to IS state after two-fiber BLSR switch on a mixed-node network with one ONS 15327 and two ONS 15454s. This issue will be resolved in a future release.
The ONS 15327 XTC card allows soft reset immediately after a database change. After making any database change (for example, changing some provisioning) it is possible to soft reset the XTC card before the database change has been written to non-volatile memory. The result is that the most recent provisioning change might be lost. To avoid this issue, before soft resetting the XTC card, wait 2 minutes from the last provisioning change. This issue is resolved in Release 4.6.
A hard reset of the active XTC in a 1+1 configuration causes CTNEQPT-PBPROT to be raised in OC-3 trunk cards and OC-12 line cards. The hard reset also causes UNEQ-P to be raised in the OC-12 line cards. This issue is resolved in Release 4.6.
On the ONS 15327 XTC, the j1 path trace values for the DS1 are incorrect. The table shows 28 entries, all with identical (but wrong) values, when an STS-1 (the only type that supports path trace on the XTC's DS1) only should have one entry. This can occur with an STS-1 circuit terminating at the XTC's DS1, in the DS1 maintenance card view of the XTC. To find the actual path trace values for the DS1 circuit, open the detailed circuit map for that circuit, right-click on the port image of the DS1, and select "j1 path trace." This issue is resolved in Release 4.6.
E Series and G Series Cards
When using a G1000-2 card, TIM-P can be mistakenly raised on a PCA circuit after a protection switch. This occurs when path trace is enabled on a PCA circuit that is no longer in use after a protection switch. To work around this issue, either disable path trace or use alarm profiling to filter out the unwanted alarm. This issue will not be resolved.
With E100/E1000 cards, a CARLOSS alarm present, and port alarms suppressed from CTC, Manual Alarm Suppression does not correctly suppress CARLOSS alarms. This issue is resolved in Release 4.6.
G1000-2 path alarm profiles applied on port 2 are not updated to reflect the correct alarm severities. This issue is resolved in Release 5.0.
Excessive Ethernet traffic loss (greater than 60 ms) may occur when the active XTC is removed from the chassis while using the G1000-2. On rare occasions, permanent loss of traffic may occur. Do not remove the active XTC from the chassis to force a protection switch. Instead, perform a soft reset of the active XTC through the network management interface. Once the XTC is in standby mode, it can be removed from the chassis without inducing excessive traffic loss. A future hardware release will incorporate improved hardware PLL circuitry on the G1000-2 line card to allow an active XTC removal without causing excessive traffic loss.
Path Protection Functionality
With a VT path protection circuit, if you inject signals with a thru-mode test set into one path of the circuit in a particular order, you may not see the appropriate alarms. This can occur when you first inject LOP-P, then clear, then inject LOP-V. This issue will not be resolved.
CSCeb24331 and CSCeb40119
If you create a four-fiber BLSR with a VT circuit on it, then delete the circuit and the ring, then created a two-fiber BLSR on the same ports, you may see an unexpected AIS-V on the path, even before any additional circuit is created. A soft switch of the XTC will clear the AIS-V condition. This issue is resolved in Release 4.6.
Rarely, CTC Network view can freeze following the deletion or addition of a node from or to a BLSR. This can result in the CTC Network view no longer updating correctly. If this occurs, restart CTC. This issue is resolved in Release 4.6.
Traffic along a running ring segment cannot be restored while a participating node is rebooting. To see this problem, in a two fiber BLSR with circuits created along a given ring segment, you must isolate that ring segment by powering down two or more nodes where one of the nodes powered down is at the edge of the segment and the others are outside of the segment. Then power up and reboot the node at the edge of the segment. The circuits along this segment will not be restored even though the nodes on the segment are both up and running. You must restore power to all nodes before the traffic is restored. This issue is resolved in Release 5.0.
BLSR Support for Mixed Node Networks
The ONS 15327 is supported for BLSR in combination with ONS 15454 nodes only if Release 3.3 or greater is installed and running on all BLSR nodes. If you wish to provision a BLSR on a combination of ONS 15327 and ONS 15454 nodes, you should upgrade to Release 3.3 or greater on all ONS 15454 and ONS 15327 nodes first.
Note To be compatible with TL1 and DNS, all nodes must have valid names. Node names should contain alphanumeric characters or hyphens, but no special characters or spaces.
In one rare case, the ONS 15454/15327 times out a user session without communicating the timeout to TL1. If this happens, the TL1 user remains logged in, although the session is actually timed out. This can occur when you log into the node with a timeout of X minutes. If the user session sits idle for all but 5 seconds of the X minutes, then you have only 5 seconds to type in a command to notify the node that the session is active. If you try this, you will likely miss the five second window, in which case the node will respond as though the session is inactive and deny access. However, because you have typed a key, irrespective of the five second window, TL1 responds as though the session is active and does not log you out (time out). You will not have access to the node and will receive a "DENY" response to TL1 commands. The error message may vary depending on commands issued. To recover from this situation, log out and log back in to TL1. This issue is resolved in Release 4.6.
The TL1 COPY-RFILE command, used for SW download, database backup, and database restore, currently does not allow a user-selected port parameter to make connections to the host. The command expects the default parameter of Port 21 and will only allow that number. This issue is resolved in Release 5.0
The far-end STS PM counts do not accumulate on an OC-48 linear 1+1 circuit even though the near-end STS PM counts on the other end are increasing. To see this issue, connect two nodes with an OC-12 or OC-48 linear 1+1 protected span. Place a piece of test equipment in the middle of the span and inject B3 errors. The near-end STS PM counts accumulate, but the far-end STS PM counts do not accumulate. To work around this issue, Use the near-end STS PM count from the adjacent node to see the far-end STS PM count for the current node. This issue will not be resolved.
The following two notes on page 5-30 of the Cisco ONS 15454 Reference Manual, R4.1 and R4.5 should be replaced.
Note G-Series cards manufactured before August 2003 do not support DWDM GBICs. G1000-4 cards compatible with DWDM GBICs have a CLEI code of SNP8KW0KAB. Compatible G1K-4 cards have a CLEI code of WM5IRWPCAA.
Note All versions of G1000-4 and G1K-4 cards support CWDM GBICs.
Resolved Software Caveats for Release 220.127.116.11
The following items are resolved in Release 18.104.22.168.
Maintenance and Administration
If a host on the same Ethernet as a given NE sends ARP requests to the NE, with a source address that is in a restricted address range (see below), the NE might reboot and other cards in the shelf reset. The NE might become unmanageable under these circumstances. The NE will install an ARP entry for the illegal IP address, with the MAC supplied in the ARP request, thereby misrouting important addresses.
Restricted addresses are those in the loopback network, 127.0.0.0/8, in the multicast networks, 22.214.171.124/4, and in the cell bus network, 192.168.100.0/24.
The workaround is to ensure that no legitimate hosts have addresses in the illegal networks, and that no compromised hosts that might generate ARP attacks are on the Ethernet. This issue is resolved in Releases 4.0.3, 4.6.2, 4.1.5, and 5.0.
In Releases 4.1.4 and 2.3.5, when TCC-B is the active shelf controller card, the NE will not send SNMP traps to the provisioned trap destinations. When TCC-A is the active shelf controller card, SNMP traps will be sent. This only occurs in software Releases 2.3.5 and 4.1.4. To work around this issue, make TCC-A the active shelf controller card. This issue is resolved in all releases other than Releases 4.1.4 and 2.3.5.
VT1 circuits might incur excessive traffic hits (greater than 50 ms) following a manual switch of the XTC. This issue is resolved in Release 4.1.4.
PWR-A/B alarms can become stuck for an ONS 15327 node in the event of a transient power failure. The alarms will clear after resetting both XTCs. This issue is resolved in Release 4.6, and Maintenance release 4.1.4.
The High Temperature Alarm is raised at 50 degrees Celsius. This is, however, not optimal on an Itemp rated system, which can tolerate up to 65 degrees Celsius. To work around this issue, the alarm can be downgraded or suppressed, but note that this will result in no temperature alarm provided at all. Alternatively, Cisco TAC provides a method of retrieving the temperature from the node, which can thus be monitored periodically for temperature-related problems. This issue is resolved in Release 4.6, and Maintenance release 4.1.3.
With multiple unnamed circuits (circuit name listed as "Unknown") on a node, where at least one is a path protection circuit, a cross-connect from one of these unnamed circuits will incorrectly appear on the Circuit Edit > Path Protection Selectors, and Circuit Edit > Path Protection Switch Counts tabs of the other unnamed circuits. Also, the State tab will show paths in the wrong column (for example, both source and destination in the CRS End B column).
This issue can manifest anytime you create multiple unnamed circuits (via TL1 or from CTC using the TL1-like option) on a node, where at least one is a path protection circuit. This issue is resolved in Release 4.6 and maintenance Releases 4.1.1 and 4.1.3.
After addition and deletion of a static route that overlaps with the internal IP addresses range, all cards in the shelf reboot. This can also happen after the node learns a similar route through OSPF or RIP updates. This issue is present in all releases through 4.1 and 4.5. To avoid this issue, do not provision static routes with a destination address in the subnet range 192.168.190.x, and avoid overlap between IP addresses in the network and the internal subnet range 192.168.190.x. If the issue does occur, reset your TCCs. This issue is resolved in Release 4.6 and in maintenance Release 4.1.3.
UNEQ-V alarms are incorrectly raised prior to connecting a TAP to a TACC, and also after disconnecting the TAP from the TACC. This issue is resolved in Releases 4.1.3 and 4.6.
VT Cross-connects downstream from a DS1 can automatically transition from the OOS-AINS state to the IS state even though the DS1 signal is not clean (for example, when there is an LOS present). This can occur when you have created a VT circuit across multiple nodes with DS1s at each end, and you have not yet applied a signal to the DS1 ports, and then you place the DS1 ports in OOS-AINS, OOS-MT, or IS. When you then place the circuit in OOS-AINS, the circuit state changes to IS (within one minute). This issue is resolved in Release 4.1.
When a DS1 port on the XTC card (ONS 15327) or the on the DS1 card (ONS 15454) is configured as ESF frame format, and is connected to external DS1 equipment that transmits a malformed Performance Report Message (PRM) on the Facility Data Link (FDL), the XTC or DS1 card cannot manage the malformed PRM and will reset each time it receives one (so the symptom of this issue is multiple repeated resets on an XTC or DS1 card configured for ESF). To avoid this issue, change the frame format from ESF to Unframed on the DS1 ports on the ONS 15327 or ONS 15454. This allows you to keep your settings on the external DS1 equipment and not lose traffic. Some functionality of alarms, such as LOF, or of any line PMs that look into the DS1 header for information will be lost, however, in this method of avoiding an XTC/DS1 reset. This issue is resolved in Releases 4.1.7 and 5.0.
Malformed IP packets can potentially cause the XTC, TCC/TCC+/TCC2 and TCCi/TCC2 control cards to reset. Repeated transmission of these malformed packets could cause both the control cards to reset at the same time. This issue is resolved in Release 5.0, and maintenance Releases 4.1.4, 2.3.5, 4.0.3, and 4.6.2.
Malformed ICMP packets can potentially cause the XTC, TCC/TCC+/TCC2 and TCCi/TCC2 control cards to reset. Repeated transmission of these malformed packets could cause both the control cards to reset at the same time. This issue is resolved in Release 5.0, and maintenance Releases 4.1.4, 2.3.5, 4.0.3, and 4.6.2.
CSCec88426, CSCec88508, CSCed85088
Malformed TCP packets can potentially cause the XTC, TCC/TCC+/TCC2, and TCCi/TCC2 control cards to reset. Repeated transmission of these malformed packets could cause both the control cards to reset at the same time. This issue is resolved in Release 5.0, and maintenance Releases 4.1.4, 2.3.5, 4.0.3, and 4.6.2.
CSCec59739, CSCed02439, CSCed22547
The XTC, TCC/TCC+/TCC2 and TCCi/TCC2 control cards are susceptible to a TCP-ACK Denial of Service (DoS) attack on open TCP ports. The controller card on the optical device will reset under such an attack.
A TCP-ACK DoS attack is conducted by withholding the required final ACK (acknowledgement) for a 3-way TCP handshake to complete, and instead sending an invalid response to move the connection to an invalid TCP state. This issue is resolved in maintenance Releases 4.1.4, 2.3.5, 4.0.3, and 4.6.2.
CSCec88402, CSCed31918, CSCed83309, CSCec85982
Malformed UDP packets can potentially cause the XTC, TCC/TCC+/TCC2, and TCCi/TCC2 control cards to reset. Repeated transmission of these malformed packets could cause both the control cards to reset at the same time. This issue is resolved in Release 5.0, and maintenance Releases 4.1.4, 2.3.5, 4.0.3, and 4.6.2.
CSCea16455, CSCea37089, CSCea37185
Malformed SNMP packets can potentially cause the XTC, TCC/TCC+/TCC2 and TCCi/TCC2 control cards to reset. Repeated transmission of these malformed packets could cause both the control cards to reset at the same time. This issue is resolved in Release 4.6, and maintenance Releases 4.0.1, 4.0.3, and 4.1.3.
In Releases 4.0, 4.0.1, and 4.1 the standby TCC+, TCC2, or XTC card might reset automatically. This can occur at any time, but only rarely. This issue is resolved in Release 4.6, and maintenance Releases 4.1.1 and 4.1.3.
Issuing a lockout span in one direction while a ring switch (SF-R) is active on the other direction may result in a failure to restore PCA circuits on the ring.
To see this issue, on a node participating in a two fiber BLSR with PCA circuits terminating at the node over the two fiber BLSR, cause an SF-R by failing the receive fiber in one direction (say, west). Then, issue a lockout span in the other direction (in our example, east). Since the lockout span has higher priority than the SF-R, the ring switch should clear and PCA traffic should be restored on spans without a fiber fault. The ring switch does clear, but PCA traffic does not restore. To correct this issue, clear the fiber fault. All traffic restores properly. This issue is resolved in Release 4.1.
If you have PCA circuits over two-fiber or four-fiber BLSR protect channels, an incorrect auto-inservice transition occurs after traffic preemption. You may place the circuit back into the OOS-AINS state after the BLSR has returned to the unswitched mode, using the Circuit Editing pane of the CTC. This issue is resolved in Release 4.1.
Path Protection Functionality
In a path protection configuration, upon detecting a double-path failure with UNEQ-P, the UNEQ-P on the protect path is not reported. This issue is resolved in Release 4.1.3.
In a non-revertive path protection configuration, when a double failure is detected on both paths with UNEQ-P or AIS-P, upon clearing the protect path defect, the UNEQ-P or AIS-P alarm may remain stuck on the working path for the node. The most reliable way to remove the alarm is a TCC side switch. This issue is resolved in Release 4.1.3.
After you perform a force switch on one of the spans of a DRI or IDRI topology with path protection-DRI circuits present, if you then apply a clear on the same span, the state will not show up immediately in CTC. This issue is resolved in Release 4.1.
If the TL1 craft port is disconnected while a retrieve level user (or a user with no timeout) is logged in, and there is a currently active CTC session, then the active TCC will reset. To avoid this, log the craft access user out before disconnecting the TL1 craft port. This issue is resolved in Release 4.6 and in maintenance Release 4.1.4.
The TL1 "COPY-RFILE" command fails when executed on an ENE through an ONS 15454 GNE. This issue occurs when a Checkpoint firewall is between the FTP server and the GNE. The 'COPY-RFILE' will work properly when executed on the GNE but fails when executed on the ENE with an ONS 15454 GNE. The workaround is to stop FTP protocol monitoring on the
Checkpoint firewall when the FTP client is a GNE and the FTP server is the COPY-RFILE server. This issue is resolved in Release 4.1.4.
Rarely, the TL1 craft port on the ONS 15327 XTC card may not respond to data sent to the port after a power cycle. A reset initiated from CTC may clear the problem. This issue is resolved in Releases 4.1.3 and 4.6.
The default state, when no PST or SST inputs are given for The TL1 command, RMV-<MOD2_IO>, is OOS instead of OOS-MT. Thus, if you issue a RMV statement, followed by maintenance-state-only commands, such as OPR-LPBK, the maintenance state commands will not work, since the port will be in the out-of-service state (OOS), instead of the out-of-service maintenance state (OOS-MT). To work around this issue, place ports in the OOS-MT state, by specifying the primary state as OOS and a secondary state of MT in either the RMV-<MOD2_IO> command or the ED-<MOD2_IO> command.
Scripts that depend on the RMV-<MOD2_IO> command defaulting to OOS-MT without specifying the primary and secondary states should be updated to force the primary and secondary state inputs to be populated. This issue will be resolved in Release 4.1.
The TL1 command, INH-USER-SECU, does not disable the userid appropriately. The command should disable the userid until the corresponding ALW-USER-SECU command is issued; however, the userid is automatically re-enabled after the user lock-out period expires. The user lockout period is set from the CTC. This issue will be alleviated in Release 4.1 by removal of the ALW-USER-SECU and INH-USER-SECU commands. The commands are reinstated correctly in Release 4.1.
New Features and Functionality
This section highlights new features and functionality for Release 4.1.x. For detailed documentation of each of these features, consult the user documentation.
New Software Features and Functionality
Open Ended Path Protection
In previous releases, you could create an end-to-end path protection circuit on any Cisco ONS 15XXX network using A-Z provisioning of CTC/CTM. This feature requires you to specify one source node and one destination node of a path protection circuit. CTC/CTM requires these nodes to be part of the network that is discovered by CTC/CTM.
With Release 4.1.x you can create an open ended path protection circuit in addition to a regular path protection. An open ended path protection circuit is a partial path protection circuit. This feature helps you create end-to-end path protection circuits where a part of the given path protection circuit is on a Cisco 15XXX network, while the other part of the circuit is on another vendor's equipment. The circuit may consist of one source point and two end points. There are two paths from the source; one path is from the source to one end point and the other path is from the source to the other end point. The source has a bridge that sends the traffic on both paths. The end points do not have any selectors and may hand off the traffic to another vendor's equipment. For bidirectional circuits, the source also contains a selector for the reverse traffic from end points to source. Alternatively, open ended path protection can be used to create a circuit with two sources and one destination. In the unidirectional case, the destination node has a selector, and the source nodes have one-way connections.
The NE defaults pane user interface is changed in Release 4.1.x as follows:
•The NE defaults pane now has a highlighted title at the top of the pane, indicating the last action taken by the user.
•If you import or export a file, the title shows the file name and the time of the action.
•If you load or apply a file to the node, the changes and the time of the action will be displayed.
As of Release 4.1.x, The following user privileges have changed:
•A Maintenance level user can back up the database and transfer a software package to the node.
•A Provisioning level user can delete and reset cards.
Protect Threshold Crossing Alarms
As of Release 4.1.x, BLSR/MS-SPR and path protection/SNCP protect thresholds at both the card and port level are inherited from the working card/port.
To be compatible with certain legacy deployments, the DS3-12E card C bit detection algorithm has changed conjunction with Release 4.1.x through an FPGA change in the DS3-12E modules.
Gigabit Ethernet Transponder
The Gigabit Ethernet Transponder is a software enhancement to existing G-series Ethernet cards that allows these cards to support transponder functionality.
The following features support Gigabit Ethernet Transponder functionality for Release 4.1.x.
Facility Loopback is supported for Release 4.1.x transponder functionality.
This applies to all G-series cards (G1000-4 and G1K-4 on the ONS 15454 and G1000-2 on the ONS 15327).
Provisionable Flow Control Watermarks
Provisionable flow control watermarks are supported for Release 4.1.x. This capability enables the user to tune the flow control mechanism on the G-Series cards for some network applications.
This applies to all G-series cards (G1000-4 and G1K-4 on the ONS 15454 and G1000-2 on the ONS 15327).

Reporting Security Problems in Cisco Products
Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you have identified a vulnerability in a Cisco product, contact PSIRT:
•For Emergencies only — firstname.lastname@example.org
An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.
•For Nonemergencies — email@example.com
In an emergency, you can also reach PSIRT by telephone:
•1 877 228-7302
•1 408 525-6532
Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to encrypt any sensitive information that you send to Cisco. PSIRT can work with information that has been encrypted with PGP versions 2.x through 9.x.
Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:
The link on this page has the current PGP key ID in use.
If you do not have or use PGP, contact PSIRT at the aforementioned e-mail addresses or phone numbers before sending any sensitive material to find other means of encrypting the data.

Locate the serial number label on your product and record the information before placing a service call.
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of the network is impaired, while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
