System Requirements

Table 1, IBM Platform Requirements, lists the minimum range of system requirements required to run CWM 9.2.09 AIX.

The selection of a proper CWM platform depends on a number of factors, such as number of CWM desktops, number of managed connections and number of statistics collected and stored. Table 2 lists recommended CWM platforms based on the size of network.

The following are additional notes for CWM platform requirements:

• For every additional CWM desktop application, there is a need for additional 8 MB of RAM beyond the standard platform configuration.

• You may upgrade the standard configuration such as CPU speed, RAM size and disk space for future expansion.

• The default disk size for the Informix raw database is 900 MB. However, Cisco strongly recommends that you provide sufficient disk space for the statistics collection process parameters that you use.

• For every additional CiscoView instance for BPX/IGX/MGX 8220, an additional 7 MB of RAM and 4 MB of swap space, beyond the CWM standard memory and swap space requirements.

• CWM 9.2.09 does not support a 17" monitor.

If You Experience Performance Problems

If you use CWM 9.2.09 on a low end machine to manage mid-range or large-range networks, the following performance problems might be observed.

CWM Performance Degradation

CWM may take a long time to synchronize with the network. Connection Management and Equipment Management (CiscoView and Equipment Manager GUI) may take long time to come up or perform any user-requested functions. You might not be able to invoke multiple Desktops from CWM as certified by Cisco for low-end systems.

Loss of Database Synchronization

CWM may drop traps generated by the network which might put the CWM database out of sync with the network. This would result in the information about nodes, trunks, ports, and PVCs might not match with the status on the network.

Required Configuration for Stand-Alone SCM

Table 2 lists the minimum workstation platform requirements to support CWM 9.2.09 stand-alone Statistics Collection Manager (SCM).

NetView Requirements

The CWM 9.2.09 release works with NetView Release 5.1 for AIX 4.3. See "Third Party Product Limitations Notes" for Netview patches required by CWM.

The default color of the background map can make it difficult to see the color of the nodes and the trunks on the map.

For IBM NetView installation requirements and procedures, please refer to the appropriate IBM documentation.

INFORMIX Requirements

The CWM 9.2.09 release uses Informix 7.23 for database operations.

WingZ Requirements

The Report Application of CWM 9.2.09 uses WingZ 2.5 or later. For proper working of the Report Application the DataLink package of WingZ must also be installed along with WingZ package.

Supported Hardware

This section provides information about hardware supported by CWM 9.2.09.

Legacy Hardware

Table 3, "Supported Legacy Hardware", lists the legacy hardware supported in CWM 9.2.09.

New Hardware

Table 4, "Supported New Hardware", lists the new hardware supported in CWM 9.2.09.

Software Compatibility

CWM 9.2.09 operates with BPX 8600 and IGX 8400 series systems running SWSW releases 9.2 or 9.1. It does not support IPX nodes running SWSW release 9.1. CWM 9.2.09 operates with MGX 8220 releases 4.0, 4.1, and 5.0 for all supported features. CWM 9.2.09 can also operate in mixed networks of 9.1 and 9.2 switch software.

Switch Software

WANCV 2.09 will operate with BPX/IGX releases 9.2 and 9.1, releases of MGX 8220 later than 4.0.15, and all available releases of MGX 8850. You should use CWM Equipment Manager to manage MGX 8220 release 4.0.15 and earlier releases. When you launch Equipment Manager from the CWM desktop, the application determines whether to launch WANCV or CWM Equipment Manager.

CiscoView 4.2

Cisco strongly recommends you use CiscoView Release 4.2 with all available Software Module Updates. WANCV 2.09 device packages are also compatible with CiscoView Release 4.1.

NetView

All event messages are now displayed in NetView's Event Browser window.

The patch "TME 10 Netview Framework Patch" is required for NetView. This patch is supplied on the CWM 9.2.09 CD. If NetView is installed on your CWM workstation, this patch is installed during CWM 9.2.09 installation.

The WANCV 2.0 release works with NetView Release 5.1 for AIX 4.1, 4.2, and 4.3.

For IBM NetView installation requirements and procedures, please refer to the appropriate documentation from IBM.

New Features and Enhancements in CWM Release 9.2.09

Cisco WAN Manager 9.2.09 has been enhanced to recognize the MGX 8230 and MGX 8250 model numbers, to support VISM Release 1.5 and Release 1.5.5, the RPM 400, and to support the BXME on Cisco BPX 8600 series and add CiscoView support for Cisco IGX 8400 series wide area switches running Release 8.5. The following CWM components have been enhanced:

• Recognize MGX 8230 and 8250 model numbers.

Discovery of the 8230/8250 operates the same as Release 1 8850 feeder discovery.

• Launch CiscoView for the IGX 8.5 switch

• New BXME card types

• RPM 400

• VISM 1.5.5

Refer to VISM 1.5 Database Tables, for a listing of the new tables added to the database structure to support VISM 1.5.5.

• VISM 1.5

Cisco WAN Manager 9.2.09 has been enhanced to support VISM 1.5 The following CWM components have been enhanced:

• Conn Proxy to support AUSM to VISM PVC provisioning

• Card Proxy and Port Proxy to support VISM-related SNMP objects

• Equipment Manager to support database population for VISM-related fields

• CiscoView to support VISM device management

• Database upgrade script

• Service agent MIB

• QBIN statistics enhancements for Cisco BPX 8600 series and Cisco IGX 8400 series wide area switches.

New Features and Enhancements in CWM Release 9.2.07

Cisco WAN Manager 9.2.07 has been enhanced to support the following features of switch software release 9.2.30:

• Multiple VSI Partitions

This feature provides the ability to configure multiple VSI partitions on a BPX. In this release, 2 partitions are supported (both PNNI and Label Switching controllers) on the same BPX.

• Frame Based Traffic Control with Policing on BXM

This feature enables the configuration of hardware to enable Frame Based Traffic Control with PPD policing for AAL5 traffic. Existing RCMP

• IGX Feeder Node over an UXM IMA Feeder Trunk

This feature allows an IGX to be a feeder node using an UXM IMA trunk. The routing node can be an IGX or a BPX using IMATM. Topology, Connection Manager and SCM are impacted, but there is no impact on WANCV.

• FRSM VHS Egress Queue Management

In Cisco MGX 8850 release 1.1.20, FRSM-VHS supports two egress-servicing algorithms. This feature is per board and can be selected by using egrQosFeature object. When it is enabled, four queue algorithms (weighted fair queueing) are used. When disabled, two queue-servicing algorithms are used. The two queue algorithm method is similar to that used in FRSM-8.

The egressQSelect object provides an option for you to assign the high- or low-priority egress queue to a connection. This option is implemented in FRSM-8. FRSM-VHS does not use this object as queues are assigned based upon channel service type. High priority and VBR-RT connections are assigned to high priority queue; and VBR-NRT, ABR, and UBR are assigned to low priority.

Table 5 lists the object mapping between the switch MIB and CWM 9.2.07 Service MIB.

New Connection Provisioning in CWM

CWM 9.2.09 supports the additional connection types listed in Table 6.

  • Port Provision for new card types; FRSM-VHS (T3, E3, HS2, 2CT3), CESM. (MGX)

  • The SRM Line Distribution feature is added in this release {MGX)

Features Not Supported

The following features are not supported in CWM 9.2.09:

• Voice connections using G729 and G729A are not supported from the Connection Manager and the Service Agent

• There is no support for Equipment Manager GUI for MGX 8220 4.0, 4.1, 5.0, and MGX 8850. CiscoView is used for equipment management of those nodes.

• MGX 8850 configuration save and restore is only supported through the Command Line Interface (CLI). MGX 8850 configuration save and restore is not supported in CWM 9.2.09.

• CWM 9.2.09 does not support the BERT feature of the MGX 8220 Release 5. You must use the MGX 8220 Command Line Interface to configure the BERT functions.

• While CWM 9.2.09 manages networks running SWSW releases 9.2 or 9.1, it will not manage IPX nodes in a SWSW release 9.1 network.

Network Limits

The SWSW and MGX 8220 (4.04 onwards) have increased their limits to support network connections of up to twelve CWM stations. No changes were required in Cisco WAN Manager Release 9.2.09 software to support this increase.

CWM can manage up to 40 different disjoint networks running switch software releases 9.1 and 9.2, provided all the networks elements have unique network IP addresses and unique names across all the networks managed by CWM. Different networks may run different versions of switch software as long as the releases are those listed above. Disjoint networks containing up to 15 nodes in each network have been tested.

CWM 9.2.09 was only tested up to 250 nodes in the field for the statistics collection application.

CWM 9.2.09 Notes and Cautions

In CWM 9.2.09, the Connection Manager GUI performs the SCR range check based on the card family and takes the intersection of all individual ranges of each card type in the card family. Consequently, some SCR values might not be configurable from Connection Manager GUI. However, it is configurable from command line interface. This limitation will be fixed in CWM 10.

In this case, you will see following error message when you attempt to modify the SCR using unsupported value.

Field: SCR: The field you entered has a range of 10 to 1412830. Please re-enter the field. 
 

Due to the nature of asynchronous behavior of ILOG client and server interaction, it is likely to have CWM client requests made before the CWM server is ready. In this case, the following error messages will be displayed on the workstation screen:

Ilb Error: Synchronous request to <unidentified actor failed by timeout>. However, if the ILOG timeout situation persists for more than five minutes, the CWM station is not functioning normally, and a service call should be made.
 

The CWM network browser does not support the access restriction imposed by the CWM security manager. For example, the CWM administrator can create a user profile which restricts the access to cards. However, that user is still able to see all cards in the network browser application.

CWM network browser does not support the access restriction imposed by the CWM security manager. For example, the CWM administrator can create a user profile which restricts the access to cards. However, that user is still able to see all cards in the network browser application.

Known Limitations

RPMs using IOS version 12.0(4) have slot numbers in its ifDescr that are unlike those for IOS version 12.0(5). This invalidates the enhancement for IOS version 12.0(5) in CWM 9.2.09 and WAN CiscoView 2.0.9, and it makes RPMs using IOS version 12.0(4) unmanageable by CiscoView.

The workaround for this problem is to upgrade RPM using IOS version 12.0(4) to version 12.0(5).

Installation

The upgrade script has changed in Cisco WAN Manager Release 9.2.09.

Existing CWM configuration files are unconditionally overwritten with default values during the CWM 9.2 installation process. If you are installing CWM 9.2.09 over an earlier release of CWM 9.2.0x, save these files manually before beginning the installation process. The following files are affected:

• /usr/users/svplus/config.sv

• /usr/users/svplus/config/userInfo.sm

• /usr/users/svplus/config/profileInfo.sm

• /usr/users/svplus/statsmgrdir/parserconfig.stats

Make sure at least 900 MB of disk space in the /usr/users/svplus area can be allocated for CWM 9.2.09 installation. In the case of an upgrade, the disk space used by the existing CWM software plus free disk space should exceed 900 MB.

If you plan to use auto install and you intend to partition the disk during auto install, you have two choices for installing the WingZ application:

1. Install WingZ in /opt/Wingz before installing CWM and then execute IntegrateWingz.

2. Install WingZ in /usr/users/Wingz after installing CWM and then execute IntegrateWingz.

If you do not plan to partition the disk during auto install or if you are using manual install, you have two choices for installing WingZ:

1. Install WingZ either in /usr/users/Wingz or /opt/Wingz before installing CWM.

2. Install WingZ either in /usr/users/Wingz or /opt/Wingz after installing CWM and then execute IntegrateWingz.

You install WingZ software from the WingZ tape or CD. Note, WingZ version 2.5 should be installed for CWM release 9.2.09. After installing, contact WingZ for a runtime license and blend it with CWM 9.2.09. Failing to do so results in the "There is a problem with the registration information for this machine. Contact your system administrator" error message when you click on the CWM Report icon.

When Informix is installed on a disk array (typically the device name is /dev/vx/rdsk/rootdg/vol03) the ownership of the device and the group ownership of the device should be set to informix. The mode of the device should be 770. Otherwise, after rebooting the machine, the "Shared memory is not initialized" error message appears on the console.

When you are installing HP/OV 5.01 over an existing version, make sure the /etc/snmpd and /etc/snmpd.conf files are removed or re-named before carrying out the upgrade. If these files are not removed or renamed, it is likely you will see the following message when trying to re-start HP/OV:

object manager name: netmon
behavior:            OVs_WELL_BEHAVED
state:               NOT_RUNNING
PID:                 -
last message:        Can't talk to snmpd; see /usr/OV/log/netmon.trace for
info
exit status:         exit(1)
 

Information left in these files causes problems for the new version of HP/OV.

These files are not removed by the ovremove program.

CWM Upgrade

You can upgrade of CWM from 9.1.x to 9.2.09. The incomplete connections in the user_connection table in SV+ 9.1 may not show properly (count) on upgraded CWM 9.2.09. However, a complete user_connection table will be properly propagated to an upgraded CWM workstation.

CWM Configuration

The default CWM configuration supports most networks. Very large networks with a significant number of PVCs (100,000 or more) require a change to the default CWM configuration for better performance during cold or warm starts of CWM.

Modifying the emd.conf File

The /usr/users/svplus/config/emd.conf file provides nineteen configuration parameters that control the operation of the Equipment Manager Switch Daemon (EMSD). Each of the nineteen parameters is preceded by a comment statement that describes the parameter. To achieve better cold and warm start performance, complete the following steps:

Step 1 Search for Tftp Timeout, and change the value from 1 hour to 2 hours.

Step 2 Search for Attempt to resynchronize, then change the value from 10 times to
40 times.

Step 3 Change the next parameter, Upload TFTP file, from 4 times to 15 times.

Step 4 Search for next SNMP shelf config request, then change the value from Minimum 600 to Minimum 300 (seconds backoff).

Modifying the tftpmgr.conf File

The /usr/users/svplus/config/tftpmgr.conf file provides configuration parameters about the TFTP Request Manager. To achieve better cold and warm start performance, complete the following steps:

Step 1 Change the NumberOfRetries value to 40 from the default value of 20.

Step 2 Change the MaxTFTPSession value to 72 from the default value of 32.

CWM Dedicated IP Ports

CWM 9.2.09 to Cisco WAN switch (outgoing): ports used in the switch

• udp: 161, snmp get/set

• udp: 2500, rtm

• udp: 69, tftp server

• tcp: 23, telnet

• tcp: 13, daytime

Cisco WAN switch to CWM 9.2.09 (incoming): ports used in CWM 9.2.09

• udp: 162, snmp trap

• udp: 8161, snmpAgent

• tcp: 8888, HP OV topology daemon

• tcp: 9999, HP OV database daemon

Unique Node ID

To provide a unique node IDs across all CWM stations, you must copy the nodes.config file to all CWM stations. The CWM upgrade procedure creates the nodes.config file from the existing node table. This file is in the /usr/users/svplus/config directory.

Security Profiles

Default security profiles and those created by your site's system administrators are currently stored on local CWM disks in the /usr/users/svplus/config directory. This is designed to allow you to have different profiles on various CWM stations. If you want all users to have the same security profiles across all CWM stations, you must copy the files listed below to all CWM stations. Following files needs to be copied manually:

1. configinfo.sm

2. defaultAdmin.sm

3. defconfiginfo.sm

4. profileInfo.sm

5. userInfo.sm

To copy the security profiles from station1 to station2, complete the following steps (as user svplus or as a user with Admin privileges):

Step 1 On station1, change directory to /usr/users/svplus/config.

Step 2 Enter the remote copy command for each file, such as:

Step 3 Repeat the above step for all five security profile files.

Window Manager

The Window Manager may occasionally crash while running CWM. This is a known problem and you need to re-login to the workstation.

In Figure 1 and Figure 2, F1 and F2 are feeder shelves, and S1 and S2 - routing nodes. If S1 becomes unreachable after receiving add request from CWM, but before sending the response back, 'middle segment' will be added on S1, between S1 and S2. However, this connection segment details will not be there in CWM database. Once S1 becomes reachable configuration changes will be sent to CWM and CWM database will be updated with the middle segment details. User can delete the incomplete connection at this time, using CWM.

However, if F1 (or F2) is an MGX 8220 shelf and it becomes unreachable after receiving add connection segment request, CWM doesn't get updated with the end segment details, even if the node becomes reachable. The database update happens whenever the next periodic Node Resync by CWM happens with that shelf.

• Similar DB inconsistency can happen in case of delete connection operation. In this case, while a multi-segment PVC is being deleted, if a node receives connection delete request, but doesn't respond to CWM, CWM doesn't delete this segment information from the database. This results in a dangling connection segment in CWM DB, which doesn't exist on the node. However, this connection segment will be deleted from CWM database eventually. The time taken for this database synch-up once the node become reachable, depends on the type of the node.

In the above two examples, if S1 becomes unreachable after receiving delete request from CWM, but before sending the response back, 'middle segment' will be deleted on S1, between S1 and S2. However, this connection segment details will not be deleted from CWM database. Once S1 becomes reachable configuration changes will be sent to CWM and CWM database will be updated accordingly.

However, if F1 (or F2) is MGX 8220 shelf and it becomes unreachable after receiving delete connection segment request, CWM doesn't delete the end segment details from the DB, even if the node becomes reachable. The database update happens whenever the next periodic Node Resync by CWM happens with that shelf.

Network Configuration

Any node with IP address 192.0.0.0 or 0.0.0.0 will not be displayed or stored in CWM database. In order to configure the correct network IP address use cnfnwip command on the switch.

Each IPX/BPX/IGX/MGX 8220/MGX 8800 node to be managed by WAN Manager must be configured with an IP Relay IP Address (cnfnwip). The gateway node must be configured with both LAN and IP Relay IP Addresses.

The IPX/BPX routing and IPX/AF feeder modes must be configured with read and write SNMP community names. The SNMP community names "public" and "private" are configured in CWM for GET and SET respectively as defaults.

The directly attached node (Gateway node) must be configured with IP Relay IP address before starting WAN Manager.

Node names, IP Addresses and NWIP addresses of the nodes in a network and across networks in multiple networks scenarios, should be uniquely configured.

Robust message updates must be enabled.

The gateway node name has to be the same as the node name specified in the config.sv file.

The maximal number of nodes can be added through the Network Configurator is 2000. Currently, there is no error message to alert you to this situation. This is a limitation of the CWM 9.2.09 back end processes.

In the case of managing standalone MGX 8850 nodes and a tiered AutoRoute network with automatic discovery enabled, the addition of standalone nodes using the Network Configurator can't take place while the CWM is synchronizing with the network.

A trap will be generated when the network synchronization is done. You can activate the standalone network configurator by running the tool: /usr/users/svplus/bin/configurator.

Service Agent

For adding a connection the connectionIndex must be 0 (for example, there is no need to do a GET on connAvailIndex). The actual index is internally generated by the connection service agent itself.

Connection Manager

In CWM 9.2.09, the Connection Template (another set of user data) is not getting propagated to other CWM workstations.

CWM 9.2.09 does not use the 'Service Rate' parameter applicable to FRSM channels, while adding FRSM channels, using the CIR instead. If you add FRSM PVCs through the command line interface (CLI) using 'Service Rate', you will unable to display all parameters of the PVC and unable to modify the PVC.

For DAS connections, deleting an end point from a segment and later adding it to another segment at a very fast rate may result in a database inconsistency.

Test Connection and Test Delay do not work for connections routed through a Cisco virtual trunk cloud when the connection originates from an MGX 8220 or BPX midpoint.

Connection Manager 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.

In the Connection Manager GUI, you must enter both the end points (node, shelf, slot, port) in the Add Connection window before entering any connection or midpoint parameters.

For an FRSM - ASI PVC connection, the error message "Remote SCR value out of range" generated by the remote BPX, indicates that the CIR value of the Frame Relay side is below the acceptable limit (cell rate) of the trunk between the MGX 8220 shelf and its routing node. To correct the problem, one can increase the value of CIR. E.g., if the trunk between the MGX 8220 shelf and the routing node is a BXM trunk, the CIR value should be at least 19.2 kbps (50 cell/sec).

ABR.FS connections cannot be added with default values for ATM-FR SIW connection. The
'ICR TO' value has to be changed.

Certain types of connections, such as VBR.1 or CBR, with policing parameters can't be modified by CWM if the default was changed using the switch command line interface.

While adding three segment frame relay connections where one routing node is IGX and another is BPX, connections must be mastered on feeders connected to BPX. Attempting to master connections on feeders attached to IGX hub will generate an "Internal error" error message, and the connection will not be added.

Three segment voice and data connections can only be added when both routing nodes are IGXs.This is due to a switch software limitation.

While adding connections originating and terminating on same feeder nodes, CWM will treat these connections as three segment connections and will add three segments (two on the same feeder node, one on the routing node) to realize this connection.

Switch software supports only ATFR and ATFST type of connections for UXM on a feeder node. CWM does not support ATFR or ATFST for ATM to ATM connection (on Connection manager GUI select Configure->New ATM-TM connection->VBR.3) the connection type on switch CLI will show as ATFR for all three segments. If you select ABR.FS connection type for ATM to ATM connection (on connection manager GUI select Configure->New ATM-ATM connection->ABR.FS) the connection type on CLI will be ATFST for all 3 segments. For all other limitations of connection type supported for UXM on feeder node please refer to the switch software release notes for release 9.2.03.

ATM-FR connections with FR endpoint on IGX/IPX running 8.4.x switch software can not be set with channel type SIW (Service InterWorking) transparent or SIW translate. This feature is not supported by IGX/IPX running 8.4.X SWSW. The connections set using 9.2.09 Connection Manager would fail.

The default values provided by the Connection Manager GUI for the Frame Relay end point parameters Ingress/Egress ECN Threshold and DE Threshold are not the same as those provided by the connection service agent.

The Connection Manager GUI uses percentage notation for both the ECN Threshold and DE Threshold. However, the service agent MIB uses the absolute value for those MIB variables. If the defaults were used for GUI and service agent, following values would be setup for the PVC:

Parameter	GUI Default Values	Service Agent
Ingress ECN Threshold	10% of Ingress VC Q Depth -> 6554	6553
Ingress DE Threshold	50% of Ingress VC Q Depth -> 32768	32767
Egress ECN Threshold	10% of Egress VC Q Depth -> 6554	6553
Egress DE Threshold	50% of EGress VC Q Depth -> 32768	32767

The switch generates error message Failure validating remote endpoint description when the PVC was modified or deleted using CWM. The problem occurs when CWM is managing a mix release network and the node mastering the pvc has an older release than the remote end, and the remote end point is in a newer card which was introduced after the older release. This is switch software limitation. The pvc can be deleted using the switch CLI.

Connection manager doesn't check for the SVC VPI/VCI partitioning range, if VPI value is ZERO and if SVC Hi VPI and Low VPI are set to ZERO on the switch. Because of this, VPI 0 can be used for provisioning. However, if you reserve only 0 for SVC range, Connection manager will not block the PVC provisioning.

In CWM 9.2.09, the FRSM-VHS card supports four separate QoS queues (versus two for legacy FRSM). The selection of QoS queue (or channel service type) on the FRSM-VHS channel has restriction on service type of the ATM routing segment. For High Priority class of connection (High Priority Queue, Q1), CWM 9.2.07 will pick CBR service type for the routing segment. For VBR-rt (real-time VBR, Q2), VBR service type is selected. For VBR-nrt (non-real time VBR, Q3), ATFR service type is selected. For ABR-FS (Available Bit Rate, Q4) or UBR (Unspecified Bit Rate, Q4), ATFS is selected.

ForeSight connections are not supported in PXM UNI ports. In other words, you are not able to create abr.fs service type connections with end points on a PXM UNI port.

Statistics Collection Manager

Cisco recommends that you use the default number of three (3) SCM children specified by CWM 9.2.09.

When you start a stand-alone SCM, the following message is not an error message: Cannot communicate with CWM, either CWM is not active or another GUI is running presently.

You should select a routing node for the SCM time sync node.

For a group of selected nodes from which stats files are to be collected by a stand-alone SCM, the collection period should be set to the same value for all nodes.

If stats files are being saved, the SCM does not purge these files even if the disk is full.

The SCM supports 3100 nodes maximum in stand-alone mode.

Whenever you perform a create_db operation, the statshistory.stats file must be manually deleted.

The following rules are used when you configure peak interval through CWM. Violating these rules will cause TFTP error 22 displayed in the SCM.

• The peak interval cannot be zero.

• The peak interval must be a multiple of the polling interval

• The peak interval must be a factor of the polling interval

• The peak interval CAN be the same as the bucket interval

The switch needs some processing time to parse the stats.enable file. Depending on the number of stats and the number of objects this time can be very large. Currently SCM has a finite value for time-out (maximum 420 seconds) to wait for the switch response. Hence there might be cases where SCM will time-out waiting for switch to finish parsing the stats.enable file. If there are excessive time-outs, try one of the following

1. Cut down on number of stats enabled and be able to get the status of stats-enabling from SCM

2. Keep the number of stats but lose the status of stats-enabling from the SCM

You can use CLI commands such as dspstatparms, dspchstatcnf, dsptrkstatcnf, dspportstatcnf and dsplnstatcnf to make sure their desired stats are enabled. Note that there can be occasional time-outs if a node is busy for that period of time, but this case at the best is intermittent and should go away once loading on the node stabilizes Following is the formula to calculate the time to enable statistics on the switch:

		time = (stats / cnt) * delay
	where
		stats = (conns * stats_per_con) +
		          (CLNs * stats_per_cln) +
	       	          (trks * stats_per_trk) +
		          (ports * stats_per_port)

		cnt = number of stats configured in one group before giving up CPU, a configurable 		parameter on the switch.
		delay = a delay time between each group of stats get enabled, this is also a configurable parameter on switch.
 

This is captured in CR CSCdj39737.

Platform

While CWM is running, if the X server crashes for any reason, then CWM should be stopped and restarted.

While CWM is running, if remote display is killed without properly shutting down the CWM Desktop, then reopening it remotely may not succeed.

CWM must be started from a CDE environment.

Reports

The Wingz "Add Comment" option is not supported for virtual trunk and ATM connections. Wingz occasionally does not scroll up the list box properly.

Topology

It may occasionally take two to three minutes to display new nodes after addition of virtual trunks. This is due to the time required to setup link0 and link1 subscriptions.

Software/Firmware Image Download

Always use the CWM ImageDownload program to do a SW/FW download. Since CWM does not make any assumptions on the filename, it requires you to tell the SW the filename and the path to download, avoiding any inconsistencies resulting from the file naming assumptions made by the getfwrev and loadfwrev commands. If the CWM ImageDownload program does not work, then there is some problem with the file transfer or the image.

SNMP Traps

• All SNMP traps now match with the MIB. In earlier releases, some of the trap enterprise Object Information Descriptor (OID) had different enterprise OIDs in previous releases. Due to this correction, old traps with incorrect enterprise OIDs from trapd.log file will not be shown in the Event Browser.

• All the CWM traps will go to CWM Events category instead of StrataView Events.

• All the nodes in the NetView topology map will appear under CWM root instead of StrataView root.

• After installation, you must run /usr/users/svplus/bin/clearOVDb.s before running ovw because the nodes under StrataView root will still be there and may result in database corruption.

• The trap.conf file in /etc/opt/OV/share/conf/C directory will be removed and replaced by default trap.conf and then merged with StrataTrapd.conf file. If you have modified the trapd.conf file, those changes will be lost. To save these changes, save the trapd.conf file (perhaps to /tmp), and merge it back.

RPM

CWM 9.2.09 supports only ATM connection type and vbr.3 service type for endpoints terminated on the RPM card.

For a RPM VCCON, the ONLY VPI value allowed is 0. To add a VPCON, an asterisk (*) should be specified as the VCI value.

If a VPI, VCI value is used to establish a RPM channel on one subinterface, the SAME VPI, VCI pair cannot be used with another subinterface. This is due to a RPM limitation. If such action is attempted, CWM 9.2.09 will emit the error 'Local/Remote end point already exists'.

CWM 9.2.09 does not support provisioning of RPM channels for subinterface values over 32767.

For a PVC involving RPM, CWM 9.2.09 supports ATM Service Type VBR only (VBR.3 for ATM-ATM and ATM-FR for ATM to FR PVCs). The UBR Service Type is NOT supported for RPM by CWM 9.2.09.

CWM 9.2.09 provisions the RPM end of a 'End to End' PVC by using the IOS command 'atm pvc..' followed by the 'addcon' command. A RPM end point added using the 'atm pvc' command CANNOT be modified/deleted using the (newer) 'pvc add' command and vice-versa.

To establish a 'channel' on RPM, two IOS commands are required:

1. atm pvc command, to add the RPM 'leg' of the channel.

2. addcon command, to add the PXM 'leg' of the channel.

If the RPM leg gets deleted (new configuration restored on RPM), CWM 9.2.09 cannot detect the condition. However, if necessary, CWM 9.2.09 can be used to delete and re-add the entire channel by reprovisioning the 'End to End' PVC.

If the PXM leg gets deleted (for example, clrallcn' on MGX 8850), CWM 9.2.09 cannot provision the channel until the RPM leg is manually deleted. To do that, you must login to the RPM card and perform the following IOS commands:

1. 'no atm pvc' command, to delete the RPM 'leg' of the channel.

2. 'no addcon' command, to delete the PXM 'leg' of the channel.

The peak and average values for a feeder PVC involving RPM is limited by the bandwidth of the MGX 8850 feeder trunk. As per 'strata' MIB, the value of average (expressed in cells/sec below) is limited for each trunk type as:

ASI/BNI

T3 : 0-96000

E3 : 0-80000

OC3 : 0-353208

BXM/UXM

T3 : 6-96000

While one CWM 9.2.09 station is used to provision connections on a specific RPM card, attempts to provision on the same card in another CWM 9.2.09 station can result in failure in provisioning of RPM connections.

Provisioning of RPM can take up to 25 seconds on average. On rare occasions, the Connection Manager GUI may time out before IOSMGR returns. The returned IOS messages are eventually updated in Result Pane on Connection Manager GUI.

The followings are the typical causes of the error message "atm pvc missing":

• A PVC already exist on a point-to-point subinterface

• A PVC with same vpi/vci already exist on different subinterface.

The typical cause of the error "add connection to PXM failed" is that the resource partition is not configured.

If one of the following error message is encountered:

• atm pvc missing

• dd connection to PXM failed

Complete the following steps:

Step 1 telnet to MGX 8850 and login to RPM card (in enable mode).

Step 2 Enter the command show log and hit <CR> to go to the end.

For other error messages returned by IOSMGR, complete the following steps:

Step 1 vi ~svplus/log/iosmgr.log

Step 2 Go to the end of the file ($G) and check the command and arguments used for expect script. Check the tracefile as shown at the end of the command.

Step 3 Open the tracefile and go to the end of the file. Examine the log of expect session.

The existing RPM connections will not be removed from the CWM database when the RPM card is pulled out of MGX 8850 shelf.

Cisco WAN Manager SNMP Agent Notes

CWM SNMP Agent Configuration Notes

The SNMP master agent is configured to use 8161 as a default port id for agent communication. The configuration file SNMPAgent.conf for the master agent is located in /usr/users/svplus/config. If you are running another Network Manager which uses port number 8161, this UDP port can be configured to some other port number in this file as follows:

Syntax:

TRANSPORT special SNMP

OVER UDP SOCKET

AT PORT 8161

The Service MIB (Connection Service MIB and Port Service MIB) uses community strings for authentication. The Connection Service Agent and Port Service Agent processes use /usr/users/svplus/config/SNMPProxy.conf file as a configuration file. The SNMP community name strings can be configured in this file as follows:

Syntax:

GET_COMMUNITY public

SET_COMMUNITY private

The SNMP community names "public" and "private" are configured in this file for GET and SET respectively as defaults.

WANCV 2.09 Notes and Cautions

Installation

• You must install the CiscoView engine CD first, then install CWM 9.2.09 CD. In the CWM 9.2.09 installation process, the WANCV 2.09 device packages will be installed automatically.

• If CiscoView is already installed, you may install additional device packages or upgrade them with the cvinstall command found in /opt/CSCOcv/bin. When upgrading packages, an old package may need to be removed with uninstallpkg before installing the new one. A good practice is to use the same revision of all WANCV device packages, and to uninstall all the previous revisions first. The installation of CWM 9.2.09 will do this automatically if CiscoView is installed before CWM.

Following are examples to install WANCV device packages:

• /opt/CSCOcv/bin/cvinstall ~svplus/wancv/AXIS.pkg

• /opt/CSCOcv/bin/cvinstall ~svplus/wancv/MGX88.pkg

• /opt/CSCOcv/bin/cvinstall ~svplus/wancv/BPX.pkg

• /opt/CSCOcv/bin/cvinstall ~svplus/wancv/IGX.pkg

Following are examples to de-install WANCV device packages:

• /opt/CSCOcv/bin/uninstallpkg AXIS

• /opt/CSCOcv/bin/uninstallpkg MGX88

• /opt/CSCOcv/bin/uninstallpkg BPX

• /opt/CSCOcv/bin/uninstallpkg IGX

• For general CiscoView information including installation, see:

http://www.cisco.com/univ-src/ccden/data/doc/cview.htm

Caution A "timeout" or "too big" error response for an SNMP get-request may produce undesired results with CiscoView 4.1 or the initial release of CiscoView 4.2.

• Use of CiscoView 4.2 with Software Module Updates available from CCO is recommended.

A typical SMU installation example (CiscoView on AIX, using C shell):

# su root

# cd /var/tmp

# mkdir nmpath; cd nmpath

# ftp 192.31.7.130

# uncompress cview-01-sol-hpov-cv42.tar.Z

# tar -xvf cview-01-sol-hpov-cv42.tar

# source $NMSROOT/etc/install.cshrc

# ./install-smu

Performance

The various timers and retry counter should be configured from the "options->properties" menu. For a typical installation, Polling and Monitoring should be about 60 seconds and Timeout should be at least 15 seconds. Faster Polling and Monitoring can be configured if conditions permit.

Network Configuration

Each BPX 8600, IGX 8400, MGX 8220, or MGX 8800 node to be managed by Cisco WAN Manager must be configured with an IP Relay IP Address (cnfnwip). The gateway node must be configured with both LAN and IP Relay IP Addresses.

The BPX routing and AF feeder modes must be configured with read and write SNMP community names. The SNMP community names "public" and "private" are configured in CWM for GET and SET respectively as defaults.

The directly attached node (Gateway node) must be configured with IP Relay IP address before starting WAN Manager.

Node names, IP Addresses and NWIP addresses of the nodes in a network and across networks in multiple networks scenarios, should be uniquely configured.
