The information in this Release Notes for Cisco WAN Service Administrator 1.1.1 supersedes all information in the Cisco WAN Service Administrator (WSA) documentation set.
The information in this release note is organized into the following sections:
The WSA documentation set includes the following manuals:
There is a correction to Cisco WAN Service Administrator Installation and Control System Configuration, Release 1.1, on page 4-6. The first time that the destination directory is chosen, the Browse button must be used to set to c:\informix.
This section describes the minimum system requirements needed to install WSA.
The categories of the system requirements are as follows:
The following are the minimum UNIX system requirements:
The following are the minimum PC client system requirements:
Informix 7.2.3 is the required version of the Informix database engine. This version is distributed on the WSA CD-ROM.
A requirement to use WSA is that any 9.1.xx release of Cisco StrataView Plus (SV+) version 9.1.06 and later must be installed properly and tested.
The SV+ Solaris server must also have libresolv.so.2 in /usr/lib.
 | Warning Cisco WSA and Cisco SV+ can not reside on the same machine. Do not attempt to install Cisco WSA on a system that already has Cisco SV+ installed. |
WSA supports the same switch versions as supported by any 9.1.xx release of SV+ version 9.1.06 and later.
The following switch software versions have been tested with WSA:
The WSA back-end Control Processor module talks to the SV+ SNMP Proxy Agent. For more information about the SV+ Proxy Agent, refer to Cisco StrataView Plus SNMP Proxy Agent.
The following caveats are applicable to WSA 1.1.1:

In the case of any data contention error messages, refer to the section Known Problems in Cisco WSA 1.1.1, CSCdm27551 and CSCdm27561.
Problem: When BXM cards configured as TRUNK-ATM to a non-AXIS node are loaded into the database, the GUI displays them as ATM, instead of as TRUNK-ATM.
Resolution: WSA_Probe and WSA_Loader now appropriately recognize BXM cards in ATM or TRUNK-ATM mode.
Problem: The wsamain database is shipped with a number of unlinked templates, associated parameters, and connection subtype defaults for service levels that no longer exist. When new service levels are created, this data can become relinked. This can lead to confusion, because data not created by the user suddenly appears.
Resolution: The wsamain database does not have unlinked templates in WSA 1.1.1.
Problem: When you invoke the Template Editor from the WSA Administration Tools bar, select the type as connection, and right click to create a New template with a newly created Service Level, the GUI automatically generates extra templates.
Resolution: WSA 1.1.1 does not automatically create extra templates.
Problem: When the NNI connection is ceased, only one PVC is deleted.
Resolution: In WSA 1.1.1 all PVC segments are deleted when an NNI connection is ceased.
Problem: Once created, nodes cannot be relocated to a different network or site, though they can be allocated to a different administrative region.
Workaround: None.
Problem: Listing ports in the Network or Location view under a node may take a long time.
Workaround: Listing time for ports is proportional to the number of ports under a node.
Problem: Starting DS0 number other than 1 for provisioning connections on non-channelized FRSM cards causes SV+ to fail.
Workaround: Always use starting DS0 to be 1 while provisioning connections with SV+ Proxy Agent for non-channelized FRSM cards.
Problem: When the connection to the server is broken while the Administrator or Explorer is running, an SQL error followed by a run time error is generated.
Workaround: When connectivity to the Informix server is broken, restart WSA applications.
Problem: The Loader assigns only some ports to Audit customer.
Workaround: The Probe discovers nodes, cards, ports, trunks, and connections using an SV+ database. The Loader loads those based upon information returned by SV+.
Problem: When you try to change the live/cease times by manually typing digits in the Add Connection Wizard, the numbers are not correctly displayed.
Workaround: Use the increment/decrement buttons to select the times.
Problem: The loader sometimes loads an incorrect trunk speed.
Workaround: None.
Problem: WSA can only support one slot type per slot, even though, in some cases, switches support multiple slot types per slot.
Workaround: Mixing slot types is not supported. Do not mix slot types on a single slot.
Problem: The Loader fails to report some IGX-ended FR-FR connections. For the ones it does report, the GUI does not correctly show the DLCI at the IGX end.
Workaround: Delete the unreported connection and manually insert a new connection through the Add Connection Wizard.
Problem: WSA cannot support channelized and non-channelized ports on the same card.
Workaround: Be sure to understand the predefined setting of channelized or non-channelized for each specific card. The following cards are set as channelized:
Problem: Database contention errors and SQL error messages occur upon refreshing a task list or within the Add Connection Wizard in the WSA Administration and Explorer GUIs, respectively.
Workaround: Do not refresh the task list during heavy traffic for WSA Control Processes, when many tasks are in WAIT/PROGRESS states. Also, create connection records in advance, using the Add Connection Wizard, during light traffic for WSA Control Processes when only a few or no tasks are in WAIT/PROGRESS states. This eliminates the database resource contention error messages and SQL error messages with codes 243, 400, and other SQL errors.
Problem: The WSA Control Processes WSA_Scheduler and WSA_WatchDog run into a database resource contention issue depending upon their command line option values.
Workaround: The default values for the Control Server options are (Korn shell syntax shown):
$ WSA_Scheduler -i -s +sched1 -c 15 -m 1 -r 30
$ WSA_WatchDog -u -l -v -i 120 -z 45
The Scheduler updates the status of the tasks every 15 seconds, based on the -c flag setting. The WatchDog updates the status of the connections every 45 seconds, based on the -z flag setting. Also, the WatchDog generates new tasks every 120 seconds, based on the -i flag setting. Based upon the installed network environment and provisioning traffic, these flags must be specified to describe the accuracy/interval with which the WSA Control Processes execute. This helps minimize or eliminate database resource contentions and SQL errors 244, 271, and other SQL errors.
Table 5, "Recommended Configuration Parameters for Provisioning Activity", presents a recommended guideline set of configuration parameters for the WSA Control Processes for provisioning activity.
| Platform | Tasks (PVCs) Relating to Customer Connection Requests | WSA_Scheduler Configuration | WSA_WatchDog Configuration |
|---|---|---|---|
Sun Ultra 10 | 20 (1 network) | -c 59 -m 1 -r 10 | -i 360 -z 35 |
Sun Ultra 10 | 40 (2 networks/1 NNI) | -c 90 -m 1 -r 10 | -i 360 -z 60 |
Sun Ultra 10 | 60 (3 networks/2 NNIs) | -c 90 -m 2 -r 5 | -i 360 -z 60 |
The numbers in this table do not guarantee 100% accuracy due to network conditions that might exist. The values are guidelines and should be adjusted to meet network conditions. | |||
