Caveats

Application

----------------------------------------------------------------------------

IVR_FCIP

----------------------------------------------------------------------------

2. Back up the FCIP configuration and other applications from the running configuration on the

switch.

3. Disable the features in use by the license. This action is disruptive to any non-FCIP IVR traffic.

switch# no feature fcip

switch# no feature IVR

4. Copy the license files off the switch as follows:

switch# copy licenses bootflash:lic-backup.tar

switch# copy bootflash:lic-backup.tar tftp://xxx.xxx.xxx.xxx

5. Enter the clear license command to clear the license.

6. Reinstall the license files.

7. Enable FCIP and reconfigure the switch.

8. Enable IVR and reconfigure the switch.

• CSCtq88900

Symptom: In an SME or IOA deployment, if the number of H->T flows that are added exceeds 512,

then subsequent disruptive platform events can leave an FCR unable to process interprocess (MTS)

messages at a rate fast enough to support the scaled configuration. This situation can cause an

MTS-buffers full condition in the FCR, which can result in unpredictable behavior. Some of the

resulting errors may be unrecoverable, and may require a disruptive restart of the flows.

Workaround: Use CFS regions if a large number (greater than 512) of application flows need to be

configured. CFS regions segment the FCR peer topology into manageable proportions.

• CSCtr50223

Symptom: On the MDS 9513 switch, when an MSM-18/4 module boots up, it sends a request to the

supervisor module to mount the modflash on the MSM-18/4 module. If there is a timeout or error in

response, the following syslog message displays:

2011 Jul 14 01:18:13 sw-dc5-br2-12 %LC_MNT_MGR-SLOT3-2-LC_MNT_MGR_ERROR: SUP mount

failed. MTS receive timedout

2011 Jul 14 01:19:06 sw-dc5-br2-12 %PROC_MGR-SLOT3-2-ERR_MSG: ERROR: PID 1144

(lc_mnt_mgr) exited abnormally, exit status (0xa)

2011 Jul 14 01:19:06 sw-dc5-br2-12 %MODULE-2-MOD_MINORSWFAIL: Module 3 (serial:

JAE1141ZB43) reported a failure in service lc_mnt_mgr

This issue might be seen when the supervisor module is unusually busy and cannot process the

mount request from the MSM-18/4 module, or the actual mount command on the supervisor takes a

long time.

Workaround: Reload the MSM-18/4 module in the same slot/module where the modflash mount

failed. A request will be sent to the supervisor to mount the modflash.

• CSCtx41288

Symptom: The label for a smart card is not detected correctly.

Workaround: None.
