MPSM Licensing Information
Recovering Feature Licenses That are Not In Use
Feature licenses are automatically returned to the license pool when the card configuration no longer
requires them. The following actions can be used to remove the configuration for featured licenses:
• Use the CLI commands to remove the feature configuration. For example, if you delete all
channelized ports (delport) on a card, the channelized feature is no longer required and will be
returned to the license pool.
• Clear the entire configuration on the service module (clrsmcnf).
• Clear the entire configuration on the switch (clrallcnf).
• Delete a redundant card configuration. This action releases any licenses reserved for the secondary
card, provided that those licenses are no longer required for other primary cards.
When licenses are returned to the license pool, they are immediately available for use on other MPSM
cards.
Saving and Restoring the License Configuration
MPSM feature licenses are backed up and restored with the complete switch configuration as described
in the “Managing the Configuration Files” section in Chapter 9, “Switch Operating Procedures”.
Caution To avoid losing feature licenses, always save the switch configuration after you move, transfer, or add
licenses, by using the saveallcnf command.
Transferring Licenses between Switches
When you transfer licenses between switches, you are removing one or more licenses from one switch
for use on another switch. To transfer licenses between switches, you will need to get a transfer license
from Cisco.com. The general procedure is as follows:
1. Collect the source and destination switch information by running the CLI command dsplicnodeid
on these switches.
2. Using Cisco.com, enter the output generated by the dsplicnodeid command, specify the licenses to
transfer, and obtain a transfer license.
3. Move the transfer license to the source switch.
4. Apply the transfer license on the source switch to remove the desired licenses and obtain a new
license key and file that can be applied on the destination switch.
5. Transfer the new license to the destination switch.
6. Apply the new license on the destination switch.
The following procedure provides instructions for transferring licenses between switches.
Step 1 Establish a configuration session with the source and destination switches using a user name with
SERVICE_GP privileges or higher.
Step 2 To display the switch serial number used for licensing on the source switch, enter the dsplicnodeid
command.
