Caveats Send documentation comments to [email protected] • CSCsq70353 Symptom: The QOS component on a standby Supervisor module looses a small amount of memory during every port flap. This loss increases over time and may result in the QOS component restarting on the standby Supervisor module. This affects standby Supervisor modules on MDS 9500 series switches only. This does not affect active Supervisor modules on MDS 9500 series switches or active Supervisor modules on fabric switches. Workaround : This issue is resolved. • CSCsc67248 Symptom: The SSH key information is not consistent between the CLI and SNMP agent. Workaround: This issue is resolvled. • CSCsq24999 Symptom: The FCIP link flaps. This issue can be identified by connecting to the associated module and issuing the show port-config internal link-events command as shown below. module-2# show port-config internal link-events Port Config Link Events Log ---- ------ Time PortNo ---- ------ Apr 30 14:21:36 2008 00223659 fcip102 Apr 30 14:21:34 2008 00474730 fcip102 Speed Event Reason 1G UP --- DOWN Loss Of Signal Alternatively, look at the eth-trace-logs for the associated Gigabit Ethernet port. On the switch issue the show ips internal eth-trace-logs gigabitethernet command as shown below.

The current interop matrix supports only TSM backup application on STK 9xxx family of drives and this application does not suffer from this issue. Workaround: This issue is resolved. • CSCsq32228 Symptom: The scheduler process fails when configured with a job configuration which generates more than 5 MB of output (for example, the show tech-support detail command which generates about 20 MB of output). If the scheduler process fails more than 3 times, then the scheduler process may not function properly and issuing the copy run start command will fail. Workaround: This issue is resolved.
