Release Notes for Cisco WAN Manager Release 15.1.50
These release notes are for use with the Cisco WAN Manager (CWM) 15.1.50 software release.
The first section describes all of the switch releases that CWM 15.1.50 supports.
Releases Supported by CWM 15.1.50
Table 1 shows the switches and releases that the CWM 15.1.50 software supports.
For additional information on supported products, see these sections:
This section describes the system requirements for using the CWM. See these System Requirements sections:
In addition to the CWM platform requirements listed in the CWM installation guide, also consider the following:
•The Ultra 60, Enterprise 450, and Enterprise 4500, which were certified with earlier CWM releases, can still be used with CWM 15.1.50. For these certified system requirements, refer to System Requirement Guidelines in the CWM 11.0.10 release notes; however, the minimum RAM needs to be 2 GB. (See CWM Server Requirements.) Problems reported by customers who choose a noncertified configuration may take more time to troubleshoot, which results in a longer turnaround time. CWM technical support is not provided for Sun configurations or products that Sun Microsystems no longer supports.
•A graphics card is required when using the Java Client access to the CWM. Video on the CWM server is only required for user access or maintenance on the CWM server. Video can be added to Sun servers/workstations. For Ultra and Enterprise, a video adapter is required.
•You can upgrade the standard configuration with more CPU speed, RAM size, and disk space for future expansion.
•The minimum disk size for the Informix raw database is 1.7 GB. However, we strongly recommend you provide more disk space for the statistics collection process. Note that if statistics are collected by using the CWM, multiple partition chunks are required to be added to Informix. For additional information on disk partitioning, refer to the Cisco WAN Manager Installation Guide.
CWM Server Requirements
Table 2 lists the system requirements for the CWM server. Note also the following about CWM servers:
•Other UltraSPARC III server models with equal or higher CPU speed and memory capacity can also be used.
•If UltraSPARC II servers are used, refer to System Requirement Guidelines in the CWM 11.0.10 release notes.
•If you are using an Ultra 60 (low-end platform), it should have at least 2 GB of RAM.
Java Client Requirements
Table 3 lists the Java Client system requirements.
Standalone Statistics Manager Requirements
Table 4 lists the Standalone Statistics Collector (SSC) or Standalone Statistics Manager (SSM) system requirements, which are the same. Note also the following:
•The file size is 2 Mbytes (typically holds statistics with peak enabled for 20-KB endpoints).
•The number of files does not increase with smaller file size.
•Average Network Transfer Rate is the required TFTP/FTP throughput to collect the maximum number of files (combination of server performance and network bandwidth and traffic).
•One SSM can control a maximum of 12 SSCs.
Table 5 lists additional system requirements for the parser in the CWM Server, SSC, or SSM. If the parser is enabled, add the applicable system requirements in Table 5 to the CWM server requirements listed in Table 2 or to the SSM or SSC requirements listed in Table 4.
Five statistics are collected from each connection segment endpoint in 15-minute file collection intervals. Collecting statistics for 4-million endpoints with five statistics per endpoint requires 80 GB of disk space per 24-hour period. You will need at least 3 x 36 GB of disk space.
Solaris Patch Requirements
This section shows the Solaris patches that you must install for the CWM and those that we recommend you install. You will install these patches after you install the Solaris 8 or 9 operating system.
Before You Begin Installing Patches
For best results, follow these Sun recommendations before you begin installing the patches:
•Use the single-user mode to install most patches.
•Shut down CWM processes before installing the patches.
•For Solaris 8, avoid installing these patches that cause problems with Informix during startup.
–In the SPARC platform for Solaris 8, 109147-36 through 109147-39
–In the x86 platform for Solaris 8, 109148-36 through 109148-39
•Not all Solaris patches or patch clusters require a reboot. If a reboot is not required, you can start the CWM after the patch is installed.
Installing the Patches
Use this procedure and sequence to install the patches.
The procedure assumes that you have installed the Solaris 8 or 9 operating system.
Step 1 Verify which patches are already installed on your CWM workstation. To display the installed patches, use the Solaris showrev -p command.
Step 2 Go to the SunSolve Patch Access website to access the patches:
(If you have a SunSpectrum contract, you can also access patches from SunService.)
Step 3 Install one of these kernel patches (that corresponds to your operating system):
•Kernel Patch 27 for Solaris 8
•Kernel Patch 12 for Solaris 9.
See Table 6 for the correct version number.
Step 4 Install the rest of the required patches if they were not already installed as part of the cluster. Depending on your situation, you may want to enter only first 6 digits of the patch number in the Find Patch field on the Sun Patch Access site and not the version extension to obtain the latest patch version.
Step 5 Install the recommended patches, as needed and desired. (Several of these recommended patches may require a service contract with Sun.)
HP OpenView Requirements
HP OpenView is used only for viewing the event log and is not required for other CWM procedures. CWM 15.1.50 works with HP OpenView 6.3 or 7.0.
HP OpenView is not bundled with the CWM CDs. You must order HP OpenView 6.3 or 7.0 directly from Hewlett-Packard and follow the H-P installation requirements and procedures. (Refer to HP OpenView Network Node Manager Products, Installation Guide, Part No. J1136-90000.)
CWM 15.1.50 uses Informix 9.4 for database operations. The Informix software is bundled with CWM included on the CWM Server CD in the CWM CD package. The Informix program is installed automatically when CWM is installed.
CWM 15.1.50 Packaging
This section describes the CWM and associated software and CDs. See Table 7 for software information and CD contents.
The CWM 15.1.50 Software Evaluation CD package includes all CWM CDs and functionality. All of the CWM features are available until the 45-day evaluation period expires. As noted in Table 7, when you order the CWM package, you receive the CWM Server CD and the CWM Documentation CD.
The following subsections list the new hardware that the CWM 15.1.50 supports, and the existing hardware that continues to be supported.

See also these sections:
New Features and Enhancements
This section describes the new features introduced in CWM 15.1.50:
•Provides sync-up operation for large networks (up to 3-million connections).
•Current Routes feature on MGX 8950, 8850, and 8830, Rel. 5.1. This feature provides the current path on which an active master connection is currently routed on in a PNNI network, current route statistical information, such as number of connections in the file that have current route information, and congestion management at the master and slave node to avoid possible congestion associated with this feature.
•1:N cold redundancy support for MPSM 16T1E1 cards, which provides the capability for configuration (add and delete) and management of 1:N cold redundancy, graceful and nongraceful switchovers, and upgrading 1:N redundant cards.
•To enable MPSM 16T1E1 support, CWM GUIs, such as the Configuration and Diagnostic centers and ChassisView, have been updated with configuration parameters for card, line, connection management, and diagnostic capabilities. This feature supports MLPPP and MPPPMux and these services: NxT1, NxE1 IMA v1.0 v1.1, T1/E1 ATM services, and NxDS1/T1/E1 frame services.
•SNMP connection transaction log enhancement to provide measurement of module and system performance, which enables a user to generate performance reports on flow-through connection provisioning.
•Support of UltraSPARCIIIi system environment.
•Upgrade paths from CWM releases 12 and 15.
•New Automated Bulk Provisioning (ABP) module (sold separately). This time-based provisioning system enables users to schedule connection and port provisioning jobs. It is a standalone software that works on top of the CWM. For additional information, refer to the CWM Automated Bulk Provisioning Guide at this website:
•Updated Cisco WAN Modeling Tools, Rel. 15.1.50 (sold separately).
•Support for assigning user profiles permission to change the node name (Node Rename feature).
•The maximum Informix raw partition size limitation has increased from 2 GB to 4 TB when the CWM is installed in its entirety on a Solaris 8 or 9 system or when the operating system is upgraded to Solaris 9 and the CWM is also upgraded.
•For MGX 8850 and MGX 8830, Rel. 5 (PXM45-based nodes and PXM1E-based nodes), CWM 15.1.50 adds support for the MPSM-T3E3-155 MultiLink Frame Relay (MFR) feature on switches running Rel. 5.0.20 or 5.1.00 software.
•For MGX 8880, 8850, and 8830 Rel. 5 nodes (both PXM1E-based and PXM45-based nodes), CWM 15.1.50 adds support for VISM 3.3 and for collecting bulk statistics from the VISM-PR.
For MGX 8850, 8250, and 8230 Rel. 1.3.12 (PXM1-based nodes), support has been added so MGX 8850, 8250, and 8230 (PXM1-based nodes) running Rel.1.3.12 now support both VISM and VISM-PR running VISM 3.3.
CWM Feature Limitations
This section describes features that the CWM does not support or features for which CWM limitations exist. See these sections:
Features Not Supported
These features are not supported by CWM 15.1.50 and later patches:
•CID level traps are not sent to the CWM to prevent potential trap flooding.
•CID level statistics are not available in bulk statistics file format from the VXSM modules.
•The CWM does not support use of the Korn shell.
•XPVC support on the FRSM T3E3 in PXM45-based switches has not been tested.
•Several windows display fields that relate to the MPSM-T3E3-155 MultiLink Frame Relay (MLFR) feature, which is not currently supported.
•When managing VISM service modules that are running VISM 3.2.10, the CWM supports only the Rel. 3.2 features.
•These VISM 3.1 features introduced cannot be accessed from the CWM: TGCP, Dynamic Payload, and T.38 Fax Relay.
•The CWM database is not populated with the MPG configuration data. Instead, the Service Agent accesses the configuration directly from the switch.
•These cards are not supported by CWM 15.1.50 and later patches: the BME card, the FRSM12 service module, and the URM, ARM, FRM, BTM, ALM and CVM service modules. To take advantage of the new CWM 15.1.50 GUI enhancements, you must upgrade to the newer supported service modules; otherwise, you would stay with CWM 12.
•These are the Current Route feature limitations:
–P2MP calls and SVC/SVP connections are not supported.
–Only master-ended (not slave-ended) connections have current route information.
–The configuration upload file contains only a snapshot of the current route information at the time the switch receives a CWM configuration upload request.
–If a node becomes congested, both of the connTrace messages that the CLI and the Current Route feature send are dropped. The CWM does not distinguish between the messages. This situation is also true for a connTrace ACK message received on a congested node.
–When a node ID is changed, follow this procedure on each network node to flush out all existing current route information and start collecting new information. Disable and re-enable the current route feature by using the new cnfndcurrte CLI command. After disabling the feature, wait for at least 9 seconds (the timeout period for a conntrace message) before re-enabling the feature to avoid processing stale conn-trace messages.
–Because the path information for a connection traversing more than 20 nodes is not stored in the current route path table, the connection does not have current route information.
•While the CWM is running, if the remote display is stopped without properly shutting down the CWM desktop, reopening it remotely may not succeed.
The following are known CWM feature limitations:
•Even though the VXSM T3 card is compatible with the MGX 8880 and 8850 PXM45 platform releases, the CWM 15.1.50 software does not discover it.
•Cisco does not recommend pointing multiple CWM workstations at the same gateway node.
•When /usr/users becomes completely full, the orbix processes cannot write to the disk and continue operations. To correct the problem, free up disk space in /usr/users and then restart the orbix processes and the CWM as follows: Stop the core and exit out of the CWM prompt, run the stoporbix2000 script, type CWM (you should see "Starting Orbix..." in the ~svplus/log/.startStopOrbix.log file), and start the core.
•When server cannot ping the client, this message is displayed on the CWM workstation: "Exception raised while calling activateLease on pseudoServer.IT_ATLI_IOP:CONNECTION_CREATION
_TIMEOUT." The GUI client initiates the call to activate the lease plug-in that the client uses to detect a server crash. When the server tries to contact the client, it fails, although the DNS is configured so the client can communicate with the server. Make sure that the client can be pinged from the CWM workstation. These are the possible reasons that the server cannot ping the client: A firewall on the client PC may be preventing it from being seen from outside or the network routing from the server to the client is not set up properly.
•When SSM is installed with the SCM Gateway configuration, the SCM GUI does not open when the primary SSM and secondary SSM are started simultaneously (or within a time gap of 30 seconds to 1 minute). Avoid this problem by waiting 2 to 3 minutes after starting core in the primary SSM before starting core in the secondary SSM in the SCM Gateway configuration.
•When a shortage of shared memory exists on the workstation, the Informix engine may generate an operating system error, as shown in this example:shmat: : operating system error 18:45:49 shmat: : operating system error 18:45:57 Error writing '/tmp/shmem.1fd4555c.0' errno = 4 18:45:57 mt.c, line 10260, thread 7148, proc id 1008, errors occurred during mt_ notifyvp.
When this error occurs, the statsparser is not able to perform database-related operations. The error can be resolved temporarily by changing the /etc/system configuration as follows:forceload: sys/shmsysforceload: sys/semsysset shmsys:shminfo_shmmax=1073741824set semsys:seminfo_semaem=16384set semsys:seminfo_semmap=5000set semsys:seminfo_semmni=8192set semsys:seminfo_semmns=8192set semsys:seminfo_semmnu=8192set semsys:seminfo_semume=256set semsys:seminfo_semvmx=50000set shmsys:shminfo_shmmin=256set shmsys:shminfo_shmmni=32000set shmsys:shminfo_shmseg=256set semsys:seminfo_semmsl=100
The long-term solution is to increase the amount of memory to support 2-million connections consistently.
•When using in-band management, only 50-KB connections are supported on the BPX-SES. To manage 100-KB connections on the BPX-SES, set up the CWM for out-of-band management.
•If an ATM IP interface (also called In-band interface) is being used to manage the switch from the CWM, the CWM cannot receive all node bring-up traps. The ATM connections required for in-band management can take time to get routed on node bring-up and therefore are not available for trap delivery at the initialization time. If this initialization time is an issue, the workaround is to configure the CWM for out-of-band management.
•Allow a 2- to 3-minute period between enabling or disabling statistics operations on the same BPX or IGX node. Whenever statistics are enabled or disabled on a BPX or IGX node and the switch is configuring statistics, enabling or disabling statistics a second time fails.
•If the Start Collection process on the SCM GUI is taking a long time, investigate whether or not collection was started with an unreachable in-band or out-of-band IP address. Use a reachable IP address to start collection with a reachable IP address, either in band or out of band.
•The SSM statistics database can go out of sync with node_ids on the CWM after a coldstart -F is executed on the server. To ensure that the node IDs remain consistent, stop and disable collection before doing a coldstart -F. A CWM-to-CWM gateway must be enabled to ensure uninterrupted statistics collection.
•When the persistent topology feature is enabled, to decommission a node in the network and take it out of the topology you must delete the node from the persistent topology data using the switch CLI. To decommission a node or to delete a trunk from the PNNI network, you must delete the entry from the persistent gateway nodes.
•To ensure all CWM servers have the same XPVC Preferred data, the CWM-to-CWM gateway must be enabled; otherwise, you must manually propagate the data to all CWM servers.
•On MGX PXM1-based feeders in the BPX network, VISM or VISM-PR terminated XPVCs can connect only to the AUSM service module. No such restriction exists for PXM1E-based or PXM45-based nodes.
•Manual node resync may appear to have failed due to the GUI timing out for PXM45/PXM1E-based Cisco MGX nodes with many connections (for example, 400K DAX endpoints).
•To correctly manage feeder nodes after they have been moved, you must first delete all trunks from the old node by using the CLI before adding the feeder back onto the system.
•When a back card is removed because the front card is not provisioned, the CWM reports a major alarm with the description "Back Card; not present." However, the switch may not show an alarm. If the card is actually not provisioned, manually clear the major alarm after determining the alarm condition is not real.
•After executing a clrsmcnf command for AXSM from the switch CLI, ChassisView shows the AXSM front card once the card is active, but no back card is found. To ensure that ChassisView recognizes the back card again, you must execute a first level manual node resync.
•RPM-PR and RPM ports/subinterfaces must be configured with a number less than 32767. If you have configured any ports or subinterfaces with a number greater than 32767, you must delete them and then re-add them using a number less than 32767.
•Note the following in regard to receiving SNMP traps:
–If you register an SNMP Manager with the SNMP Agent without changing the bit-mask (if you accept the default of FFFFFFFFFFFFFFFF), you receive all SNMP traps, including 25302 and 25303.
–If you register the SNMP Manager with a non-default bit mask because you do not want certain groups, such as FFFFFFFFF10701555, you do not receive trap 25302 and 25303, even though you have registered for that group.
–If you deselect a currently undefined group such as Group 28, that is a bit mask of FFFFFFFFEFFFFFFF, you can then add traps 25302 and 25303 by editing the trap_filter.conf file and adding these lines to Group 20 # Network Connectivity Status Change Traps: TRAP 25302 and TRAP 25303.
•Performing a switchcc command on a controller card in an IGX or BPX node forces the CWM to resync with the node again. This causes a delay in receiving status information.
•Changing the line, payload, and medium types of VXSM-4OC3 causes the CWM to perform a whole card resync when you change any of the following: the medium type between SONET and SDH for SONET physical line, the payload type between T1 (VT 1.5 VC 11) and E1(VT 2 VC 12) for the STS or STM (Au) path or between T1 (VT 1.5 VC 11) and DS3 for the STS path, or the tributary path between Au4 and Au3 for the STM path in the SDH medium. (A whole card resync takes several minutes to complete.)
•If you remove and then immediately add back the same IGX feeder when the CWM is running, the CWM establishes two LINK 0's with the node. This is treated as a delete, and the node is deleted. In this situation, Cisco recommends you either remove and add the feeder when the CWM is down, or, after adding the feeder, restart the CWM.
•Changes made to the node name through the Configuration Center are updated automatically in the Tree and Inspector views. However, the node name in the title bar of the internal frame does not update automatically. To make this change, close and reopen the internal frame. You can also update the attribute values in the internal frame by using the Refresh button of that internal frame.
•After the Line Send parameter LineSendCode is modified by using snmpset, the database is not updating it, which shows the parameter as inapplicable (shows the value as -1). For additional information, refer to CSCin50480 online.
•The "l_network_id" field in the connection segment or port tables may not be populated correctly. To ensure collection of an accurate network ID, use the "netw_id" field from the "node" table.
•Note the following in regard to the managing a PXM45-based MGX node and populating the "peripheral" table: If you are running a release earlier than 4.0.10, CWM 15.0.00 does not populate (update) the peripheral table. If you are running a 4.0.10 or later release, the status field in the peripheral table gets updated only during node resync. (If you are managing a PXM1-based MGX node, the peripheral table status field does not get updated.)
•If the log level for the CWM EM module is set too high or set above the production default value and many configurations are changed on the switch during a warm start, the sync-up performance is impacted during the warm start.
•SmartLogging is a special feature for CWM debugging available when the log level is set to Level 2. It dumps a configurable number of detailed log messages to log files for each Level 2 log message. For example, when SmartLogging is enabled, an SNMP failure that triggers a Level 2 log message dumps log messages at all levels immediately before and after this event. Because the feature can impact performance due to excessive log messages. it should be disabled in normal operation and enabled only when needed for monitoring performance.
•In regard to the The Forced Deletion feature, note that it does not support XPVC connections. They cannot be force deleted. The feature removes only the unused connection descriptor from the workstation on which it is performed. Other gateway workstations continue to show the descriptor. To clear it completely, you must force delete the unused descriptor at each gateway workstation.
•Occasionally, when you move linked nodes around in the Topology screen, the link does not automatically follow the nodes. Then it looks like the link is not connected to the nodes. Either move the affected nodes around within the window or refresh the Topology screen. When the screen refreshes, the link automatically appears connected to the appropriate nodes again.
•Using the Group Nodes feature affects only your view of the networks. Other users, even those who log into your workstation, do not see the groups you have made.
•After a previously saved configuration file is loaded by using the CWM Config Save & Restore feature, the Tree View continues to show some ports that are not in the restored configuration file. Attempting to configure these ports results in an error. In this case, perform a manual node resync.
•When setting up VISM connections, the VPI value in the VPI/VCI Selector window is grayed out with the VISM card slot number. If VISM is sitting in a feeder node, the VPI value in the VPI/VCI selector is grayed out as zero.
•Ports on PXM45-based nodes which are associated to a trunk display as Trunk Ports, however, ports that are carrying signalling protocol information display as User Ports. Because they are carrying information, you cannot provision connections on these ports. Attempting to do so results in an error being displayed. Choose another port.
•Virtual Ports on BPX are displayed in the Tree View application under the physical Line section as physicalPort.virtualPort.
•The PNNI ports on the PXM1 card of an SES node are not displayed in the Tree View.
•The administrative state of the PNNI ports is not aggregated into the total administrative state of the port. The Inspector View application shows both the total administrative state of the port and the administrative state of the PNNI ports as two separate items.
•The Loss of Cell Delineation alarm on the AXSME, AXSM-XG, or MPSM-OC3 cards may not get propagated from the switch to the CWM. For the AXSM cards, a line or path alarm is present, but the MPSM-OC-3 card could have an LOCD alarm triggered without any line or path alarm that is present. The line would show in the CWM as clear, while it is actually in alarm.
•With MPSM-OC3 cards, after you replace an OC-3 back card with a DS3 back card or vice versa, you need to do a coldstart.
•Occasionally, WANDEST fails to install immediately after a CWM 15.1.50 and Service Agent installation on a workstation running Solaris 9. This error message appears: "Informix is not in on-line mode." The workaround is to install WANDEST by using the C shell (csh).
•In the Connection Manager, the Service Type field displays some nonapplicable service types for SPVCs; however, the CWM displays an error if you select one of these nonapplicable service types.
•After adding a connection loopback through the Diagnostic Center GUI, there is no indication that the connection is in loopback. You have to use the CLI to verify that the connection is in loopback.
•If a valid network.conf file is not present, the CWM may not start properly and may cause a topod core dump.
•Because of a device limitation, an SCT greater than 255 cannot be associated with SCT manager.
•An SSC can be added to only one SSM or CWM at a time.
Configuration Center Limitations
When the connection modify dialog box is already open, another user can delete the connection using the CMGUI delete option.
The Connection Management section of the Configuration Center GUI for preferred route displays all available trunks without considering the traffic class. As a result, it is possible to set a preferred route for a CBR connection traversing trunks that do not support CBR traffic.
While adding connections originating and terminating on the same feeder nodes (MGX8220 only), the CWM treats these connections as three segment connections and adds three segments (two on the same feeder node, one on the routing node) to realize this connection. This is because the ASC cannot route traffic. If you want to pass traffic between two cards in an MGX 8220 chassis, regardless of how connectivity is added, the actual physical connectivity that has to be built is a connection from each endpoint to the ASC and then a looping segment on a BPX.
RPM on PXM1-based MGX 8850/8230/8250 is provisioned by using telnet because the RPM does not support SNMP SETs. This should be transparent in daily operation. For more details, please refer to the specific RPM switch CLI release notes.
Occasionally, when the databroker is busy deleting SPVC connections on a PXM1E-based node this error message appears: "can not delete connections. Failed to communicate with databroker." The error message can safely be ignored because the connections are correctly deleted on the switch.
HP OpenView Limitations
All event messages are displayed in the HP OpenView Event Browser window. There is a limit of 2000 pending messages on the Event Browser. If there are more than 2000 messages to be processed and displayed by the Event Browser, it may exit.
The WAN network icon in the network node manager is no longer automatically created when running CWM 15.1.50. Use the Network Monitor map instead.
Note these SSM issues:
•To collect connection statistics, statistics need to be enabled on the individual connections by setting the stats enable flag to true on each connection. If the user enables connections statistics only on SCM but does not set the stats-enabled flag to true on the connection, the statistics are not collected for that connection. Because no mechanism or warning to the user exists to have this enabled on the connections, the CWM does not display an appropriate error message.
•When enabling statistics by selecting multiple nodes at a time in the SCM, enabling statistics on all the nodes only succeeds when either all of the nodes have the same card types or all of the nodes only contain cards of the same family.
•Occasionally, when high connection counts are enabled on the SES, and statistics collection is enabled, the SES node is not getting synced up. The workaround is to disable statistics collection in the SES. Refer to CSCdw32076 for more information.
•The statistics collection manager retrieves SPVC connection statistics data from BPX-SES nodes, however, only 15 minute collection buckets are supported on the SES.
•The same limitation of only 15 minute collection buckets applies for MGX 8850 PXM45-based nodes with AXSM. No such limitation exists for AXSM-E.
•Only 15-minute collection buckets are supported for PNNI statistics.
•Peak statistics are not supported for PNNI statistics.
•If the PXM45 release is less than 4.0(0.0) PNNI historical statistics can not be enabled.
•The BPX-SES does not support PNNI statistics collection.
•The CWM does not support statistical alarms for lines on PXM45-based MGX nodes.
•The following statistics for SRM and SRM/E T3 lines can be enabled on the switch, but are not supported by SCM: 28 dsx3LCVCurrent, 29 dsx3LESCurrent, 30 dsx3LSESCurrent, 31 dsx3PCVCurrent, 32 dsx3PESCurrent, 33 dsx3PSESCurrent, and 34 dsx3CCVCurrent.
•HP OpenView is supported on SSM. SSM processes generate CWM traps.
•At least one CWM must be running, with the nodes synced up, for SSM to work normally. SSM uses the CWM server workstation to get traps while enabling statistics for cellbus-based service modules on MGX 8850 and PNNI statistics on BPX.
•The WANDEST server must be up and running on the CWM server workstation. SSM gets the node, node_info, card, network, rsc_part, bis_object tables from the CWM server workstation using WANDEST.
•If the statsmaster SSM/CWM is down or unreachable in an SCM Gateway setup, the statsmaster must be changed on the switch to a machine that is up. The statsmaster is needed for SCM statistics enabling/disabling.
•Inan SCM Gateway setup with statistics collection going on, after switchover the old statistics data is not moved to the new Primary CWM/SSM machine.
•SSM does not receive traps on Node/Card Deletion, so statistics collection must be stopped and disabled before deleting a node/card on the network. Also SSM does not receive traps on Node/Card Add messages, so the WANDEST upload must be received before the node/card can be seen in the SCM GUI on SSM.
•In SSM, statistics collection must be stopped and restarted after changing the node name or changing the node FTP password.
•Statistics data is stored on in statsdb database.
•Statistics parsing is only supported for the statsdb database on the SSM machine and the CWM machine. Statistics parsing is not supported for the stratacom database on the SSM and CWM machine.
•Stop statistics collection before upgrading a node image.
CWM-to-CWM Communication Limitations
This section describes CWM-to-CWM communication limitations:
•The secondary CWMs have to wait for the primary CWM to finish syncing up with the network. Trap 28075 (svDatabaseInSync) is sent when the primary CWM has finished syncing up with the network.
•All the CWM workstations managing the same network must have seed nodes or gateway nodes that have IP addresses within the same network. All the CWM workstations should not all point to the same gateway node, but the gateway nodes they point to should be on the same network.
•If an IP address is entered as gateway in the network.conf file and the DNS entry is missing for the gateway node IP address, the Auto-Route network is not discovered.
•The Configurator can be started on either the primary CWM or the secondary CWMs, but Add, Modify, or Delete operations by using the Configurator can only be performed on the primary CWM.
All of the above CWM-to-CWM communication limitations listed also apply to the SCM gateway.
Network Monitor Limitations
In a single routing node PNNI network, the node is managed using the IP address specified in the network.conf file.
In the case of a PXM45-based or PXM1E-based MGX network, the PXM45-based or PXM1E-based MGX nodes are managed by using the primary IP address. The primary IP address is specified by using Option 7 or 8 (depending on chassis type) in the cnfndparms CLI command. Configure the trap IP with the primary IP address. PXM1-based MGX nodes connected to PXM45-based MGX nodes are managed through the atm0 IP. If atm0 is not set, the LAN IP address is used to manage the PXM1-based MGX nodes. Use the cnftrapip command to configure the trap IP accordingly.
In CWM 15.0.00 and later, the SHOW_TOPO_VIEW flag in the CMSCClient.conf file is used to configure whether or not nodes and trunks are displayed in the topology display of the Network Monitor application at CWM startup:
•SHOW_TOPO_VIEW 1 means that when NWTopology opens, users can see nodes and trunks in the topology.
•SHOW_TOPO_VIEW 0 means that when NWTopology opens, users cannot see nodes and trunks in the topology.
In releases earlier than CWM 15.0.00, a flag named TOPO_SHOW_MAP in the /usr/users/svplus/config/CwmGs.conf file was used to configure whether or not nodes and trunks are displayed in the topology display of the Network Monitor application at CWM startup. The TOPO_SHOW_MAP flag is now obsolete. Use the SHOW_TOPO_VIEW flag in the CMSCClient.conf file instead.
CWM 15.1.50 adds these new flags in the CMSCClient.conf file:
•SHOW_ROUTING_TRUNK_TREEVIEW True means that the TreeView displays the routing trunk folder in all applications. The routing trunk folder contains all of the routing trunk information. The default is true. If you set the SHOW_ROUTING_TRUNK_TREEVIEW parameter to false, the routing trunk information is not retrieved from the inventory server and the TreeView in all applications does not show the routing trunk folder.
•SHOW_SORTED_TREEVIEW True means that the TreeView in all applications shows sorted tree node names. The default is true. If you set the SHOW_SORTED_TREEVIEW parameter to false, the tree node names are not be sorted in the TreeView for all applications.
•ACCESS_TROUBLE_TICKET_SEND_EMAIL True enables the Send button of the Trouble Ticket dialog in the Diagnostics Center. The default is true. If you set the ACCESS_TROUBLE_TICKET_SEND_EMAIL parameter to false, the Send Button in the Trouble Ticket dialog in the Diagnostics Center is disabled.
CWM Notes and Cautions
Because of the asynchronous behavior of the ILOG client and server interaction, CWM client requests may be sent before the CWM server is ready. In this case, this error message appears:Ilb Error: Synchronous request to <unidentified actor failed by timeout>.
Note If the ILOG timeout situation persists for more than 5 minutes and the CWM workstation is not functioning normally, you should call service.
Parameters that the Network Monitor or Configuration Center displays that do not apply to an element, such as a line or a trunk, often contain the value -1. Consider this the same as Not Applicable.
Installing CWM 15.1.50
This section provides important information about installing or upgrading the CWM server. To install or upgrade the server, refer to the CWM 15.1.50 installation guide at this URL:
You can upgrade to CWM 15.1.50 from CWM 15.0.00, Patch 4, or CWM 12.0.00, Patch 3. To upgrade from an earlier release, refer to the above-referenced CWM 15.1.50 installation guide and the CWM 15.0 release notes at this URL:
This important background information is provided to help you install the patch successfully.
•Naming Managed Nodes
The name of each node that the CWM manages must be unique. Duplicate node names are detected if both node names are found in the PNNI networks. Duplicate node names are not detected if one node is in the AutoRoute network and the other node is in the PNNI network.
•Core File Management
In the past, core files were created without unique names and then overwritten. Now, for each core dump, a unique directory is created under ~svplus/corefilesdir/. Each directory is named as follows: <Core.<processName>.<pid>.mmddHrMinSec.
These directories have these contents:
–Core file named <processName>.<pid>.mmddHrMinSec.core
–Information file with dmesg, onstat -d, pstack, and other details named "<processName>.<pid>.mmddHrMinSec.info"
–Corresponding log file(s) named "<processName>.<pid>.log"
•Cisco Info Version
CWM 15.1.50 supports integration with the Cisco Info Center (CIC) application so the two applications can function together. To facilitate this integration, CWM 15.1.50 includes a tar file that can be installed by using the CIC update utility (nco_update). This tar file is provided in a format that the update utility can process on the CWMAgent CD-ROM.
The 15.1.50_SNMPAgent.tar.gz file contains the CIC36xPatch004CWM151.tar file, which contains rule files that are compatible only with CIC 3.6.1. To use these rule files, you must install CIC 3.6 or 3.6.1.
If you want to continue using CIC 3.6.0 or 3.5 with CWM 15.1.50, save and then apply the CIC36Pipp000CWM15 tar file that is available in the CWM 15.1.50 SNMP Agent CD instead.
For more information on CIC, refer to this URL:
CWM 15.1.50 supports C-Note version 3. Before the Orbix cmldomain services for C-Note are started, the CWM core must be started and core processes should be running. Add the IP address of the C-Note workstation to the /opt/ssng/config/CMLLogin/SnmpPublisher.xml file by entering this command:vi /opt/ssng/config/CMLLogin/SnmpPublisher.xml
The line you add should look like this, substituting your actual C-Note workstation IP address for one in the example below:<ipAddress>172.28.140.218</ipAddress>
•Numbering for Release 9.4 IGX Feeder Nodes
When an IGX is added as a feeder to a SES/BPX or MGX node, it has a default node number that may not be unique within the network. If it is not unique, it needs to be modified to a unique node number by issuing the rnmnd <x> CLI command, where x is unique with regard to all other auto-route nodes.
To find the other node numbers, use the dspnds +n CLI command. If you fail to do this, the CWM Databroker may have an incorrectly formed hybrid connection database, and the CWM GUI may show the connection as incomplete.
The security and user profiles are stored in the database as user_info and sec_profile tables. All CWM systems in the same domain have the same data in the user_info and sec_profile tables through CWM-to-CWM communication. The user_info and sec_profile tables do not get dropped when the coldstart command is executed during a coldstart. They can only be dropped by executing the coldstart command with the "-F" option.
The Security Manager GUI can be started from the Network Monitor main window in the primary CWM system.
The CWM user to be added to the database has to be a valid UNIX user because when a user logs in to the CWM desktop, the user gets authenticated against UNIX. The user's password must match the one defined in the UNIX system.
After creating a new database by executing the coldstart script, a database inconsistency will result if the CWM is restarted (stop core and start core) before it is synchronized with the network. In this case, rerun the coldstart script to avoid database inconsistencies. Do not use the SV+CreateDb tool for this purpose.
When a gateway node is upgraded or rebuilt before the CWM has synced up with the network, the CWM must be cold-started (create CWM database and restart CWM) to ensure CWM database consistency.
The user-supplied network name can be up to 10 characters long and should use only alphanumeric characters (no periods).
For the IGX ports, the asi_line table is populated with the 1-based port number and not the 0-based port number.
•RPM Management Limitations
–RPM-PR is not supported on MGX PXM1-based nodes managed by ChassisView in CWM 15.1.50. The applicable trap is missing so the CWM cannot monitor the back card.
–For both RPM and RPM-PR cards managed by ChassisView in CWM 15.1.50 that are in standby state, the card status displays as blue. For other types of cards, stand-by card status displays as yellow.
–For both the RPM and RPM-PR card types, hardware and firmware revisions are not populated in the database.
–The RPM back card support feature is disabled by default. To enable the feature and obtain RPM back card information, edit the emd.conf file before starting the CWM core. Note that when back card support is enabled, back card information is polled from the switch only during a coldstart or a manual resync. After that, any back card configuration or status changes are not updated until you perform another coldstart or a manual resync.
–The CWM does not distinguish between the Ethernet back card versions installed with the MGX-RPM-128M/B or RPM-PR. No difference in functionality exists.
•ChassisView Operation After Card and Line Switchovers
When two cards are in a redundancy relationship, the primary card (i.e. the logical slot) is used to display the ports and lines for all provisioning and troubleshooting activities, even if the primary slot becomes a standby. The secondary slot does not show any ports and lines under it even after it becomes active. Provisioning is allowed only on the working line of an APS pair, irrespective of whether that line is currently active or not. However, both the working and protection lines are monitored.
In ChassisView, the ports on the card only display if they are available. Ports do not display on the secondary slot, even after it becomes active. The back card appears as blank, not with grayed-out ports as in previous releases that used CiscoView for equipment management.
•Equipment Management Configuration Notes
–In the emd.conf file, the OORequest and OOStart parameters should be customized, depending on network. The OORequest parameter defines the number of configuration files per node that can be requested at one time, with a maximum of 32 configuration files concurrently per node. The range is 1 through 32, and the default is 32. The OOStart parameter defines the number of OOEMC child processes. The range is 1 through 25, and the default is 6.
–All of the PNNI nodes that the CWM manages (PXM45-based 8950, 8880, and 8850 nodes; PXM1E- based 8950, 8850, and 8830 nodes; and BPX nodes with SES shelves) are distributed among OOEMC processes.
–The number of nodes that a single process manages is computed by dividing the number of PNNI network nodes by the number of processes that OOStart defines. Assume that the number of nodes that one process manages is called MANAGED_NODE_COUNT. Then, MANAGED_NODE_COUNT * OORequest must be less than or equal to 200, which can be achieved by increasing the OOStart or reducing the OORequest. The normal range of OOStart is 5 to 20. If the OOStart value is increased beyond 10, the number of DMD processes has to be increased or the shared memory overflows.
•Network Monitor Server Configuration File (NMServer.conf)
Two parameters in the NMServer.conf configuration file—HELLO_EVENT_INTERVAL and EVENT_REDELIVERY_COUNT—are tied to the NMSERVER_DISCONNECT_TIMEOUT parameter in the CMSCClient.conf client configuration file. The NMSERVER_DISCONNECT_TIMEOUT parameter value needs to be set to the same number as the HELLO_EVENT_INTERVAL value times the EVENT_REDELIVERY_COUNT value. The range for HELLO_EVENT_INTERVAL is 0 through 600, and the default is 60. The range for EVENT_REDELIVERY_COUNT is 0 through 10, and the default is 3. The default for the NMSERVER_DISCONNECT_TIMEOUT parameter is 60 times 3, or 180.
If you change any of these parameters, they must be adjusted so the HELLO_EVENT_INTERVAL value times the EVENT_REDELIVERY_COUNT value continues to equal the NMSERVER_DISCONNECT_TIMEOUT parameter value.
The Network Monitor Server configuration file (NMServer.conf) also contains the PERIODIC_RESYNC_INTERVAL parameter. This parameter defines the interval in hours between periodic resyncs. The range is 2 through 24, and the default is 8. You can also disable the periodic resync feature by setting the PERIODIC_RESYNC_INTERVAL parameter to 0.
Creating a CWM Auto-Restart Shell Script
This section describes how to create and configure a shell script that automatically starts the CWM core after a reboot. To create this shell script, you need to use a text editor to create a new file containing the commands that you want the script to execute.
Use this procedure to create a script that uses the vi editor and shell commands to automatically restart the CWM core after the workstation has been rebooted.
Note Several minor errors that existed in the past in the CWM Auto restart shell script have been corrected in the script that follows.
Step 1 Log in to the CWM workstation as user root:$ su
Step 2 Change to directory /etc/rc3.d:# cd /etc/rc3.d
Step 3 Create a shell script of the form: Snn <filename>, where nn is the relative sequence number for starting the job under
/etc/rc3.dby entering this command:# vi /etc/rc3.d/S99init_sv Since this script does not currently exist, the vi editor will open on a blank line, waiting for you to enter the script commands.
Step 4 Create the shell script by entering these lines:******************************************************************#!/bin/sh# Check if Informix configuration is going on while [ ! -z "`ps -ef | grep S98init_db | grep -v grep`" ]doecho "Informix initialization in progress...." >> /usr/users/svplus/log/.start_stopCWM.logsleep 5done# Start Orbix E2A ... as svplus echo "Starting Orbix E2A ..." >> /usr/users/svplus/log/.start_stopCWM.logsu - svplus -c /usr/users/svplus/scripts/startorbix2000 >> /usr/users/svplus/log/.start_stopCWM.logsleep 5# Running Guard process ... as svplusecho "Running Guard process" >> /usr/users/svplus/log/.start_stopCWM.log su - svplus -c /usr/users/svplus/scripts/Install/RunGuard &# Start CWM core process ... as svplus su - svplus -c /usr/users/svplus/scripts/start_SV+ &******************************************************************
Note To save your changes while using the vi editor, press Esc, colon (:), then wq!.
Step 5 Provide execute permissions for
/etc/rc3.d/S99init_svby executing this command:# chmod 755 S99init_sv
To auto restart Informix after reboot, a shell script has been created automatically during the initial CWM installation. This script is called
/etc/rc3.d/S98init_db. You need to make sure that the filename of your newly created autorestart shell script has a script number (the second and third characters in the filename) greater than 98. Also, your newly created autorestart shell script cannot have the same script number as any other script files in
For more information on configuring this feature, refer to the
SNMP Service Agent Trap Limitation
This section describes the SNMP Service Agent trap limitation with the PXM1-based MGX nodes. The type of traps that the CWM collects from adding and modifying connections on Cisco MGX PXM1-based nodes running release 1.3.00 and onward can be configured by using the cnfchantrapenbl and dspchantrapenbl CLI commands:
Use these commands to select either Default (the same legacy traps plus trap 50601 to be sent) or Enable (only trap 50601 to be sent for every connection addition or modification).
If the dspchantrapenbl command is set to Default, you can use the cnfchantrapenbl Enable command to change to collecting only trap 50601 when CWM 15.1.50 is running.
However, if you are currently collecting only trap 50601 (the dspchantrapenbl CLI command is set to Enable and you decide to configure the node to send legacy traps for every connection addition or modification by executing the cnfchantrapenbl Default command, all CWM workstations monitoring the node must be shut down (the core must be stopped) before you execute the command.
To determine which CWM workstations are managing the node, run the dsptrapmgr command.
This section lists known and resolved issues in the CWM 15.1.50 and WANDEST 2.6.50 software:

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)—Your 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 operation 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 your network is impaired, but 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.
