MPSM Licensing Information
Caution To avoid losing licenses during a configuration restoration, save the switch configuration at the source
and destination switches by using the saveallcnf command.
MPSM License Alarms
MPSM feature license alarms can occur at the node level or the slot level of the switch. The following
sections describe these alarms:
• Node License Alarm
• Slot License Alarms
Node License Alarm
Node license alarms occur under the following conditions:
• A switch configuration that was saved before licenses were added or transferred to and from the
PXM license pool has been restored. Any mismatch between the actual license sequence number and
the restored license sequence number generates a minor node license alarm. To prevent this type of
alarm, always save the switch configuration (saveallcnf) after you move, transfer, or add licenses.
• The switch configuration is restored on a different node, or the Cisco MGX chassis is replaced with
another chassis. Because licenses are authorized for a specific backplane serial number, such
conditions will cause a mismatch between the physical backplane serial number and serial number
recorded in the database.
When a node license alarm is raised, all cards that are using feature licenses go into the slot license alarm
state. If no licenses are in use by the cards, no slot license alarms will be raised.
On PXM45 and PXM1E platforms, use the PXM dspndalms command to troubleshoot the node license
alarm. As shown in the following example on the PXM45 platform, the output of this command will
indicate if the switch is in the node license alarm state:

Node license alarms are cleared by validating licenses in the license pool. This is done by applying the
special Rekey feature license to the node using the cnflic command. When the pool licenses are
validated, any existing slot license alarms are also cleared and normal operation is restored. For the
procedure to rekey feature licenses, see “Rekeying Feature Licenses”.
Note If the switch is in node license alarm, you must rekey the PXM license pool before proceeding with any
other license management tasks.
