Related Documentation
–
A Registered State Change Notification (RSCN) is not sent to zoned members.
–
The device-mapping entry port world wide name (pWWN) associated to a device alias is not
displayed in the Dynamic Port VSAN Membership (DPVM) database.
–
The show running-configuration ivr command does not display the changes when a device
alias member in an Inter-VSAN routing zone (IVR zone) is renamed.
–
The port world wide name (pWWN) associated with the device alias is found dissociated in the
port security database.
–
A device alias member is not found in the port security database.
Condition: This situation occurs when all or one of the conditions is met:
–
A user attempts to perform a device-alias operation in batch, such as:
• Renaming an offline device alias to an existing online device alias or vice versa.
• Multiple commands are entered using the same device-alias name before a commit.
–
A device alias was renamed.
–
A device alias was deleted and an existing device alias is renamed to the deleted device alias in
the same commit.
–
A device alias, which is not configured, resides in the DPVM database and an online device is
renamed to the former.
–
The IVR distribute option is enabled and the device alias is in enhanced mode, and the changes
in a device alias is not updated to the IVR running configuration.
Workaround: Add the offline member to the device alias database, revert to the previous name if
you have renamed a device alias, and flap the ports that are connected to the affected zone member.
• CSCuh57761
Symptom: Multiple port security members that are mapped to a switch WWN (sWWN) logging
point are not fully distributed to the peer switches. The following error appears after an Cisco
In-Service Software Downgrade (ISSD), followed by entering the port-security commit command:
Internal CLI error: Timer expired
Condition: This situation occurs after an ISSD from Cisco MDS NX-OS Release 5.2(8b) to 5.2.(1).
After creating and committing port-security entries that map multiple port security members to the
same sWWN, all entries are not distributed to the peer switches.
Workaround: None.
• CSCue31727
Symptom: A user with the priv-14 role does not inherit rules from the priv-0 through priv-13 roles.
Condition: This situation occurs during a normal operation.
Workaround: Create users with roles from priv-0 to priv-13 and log in, or log in to the switch using
AAA authentication where users with certain user levels are identified.
