The switch license pool serves as a depository for all licenses installed on a switch. When a card needs
to use a license, it checks the license out of the depository and the license becomes unavailable to all
other cards while it is checked out. For example, if a standard ABR connection is provisioned on an
MPSM-8T1E1 card configured for Frame Relay services, a rate control license in the pool is checked
out or allocated to that card. If the ABR connection is removed and no other ports on the card have
provisioned standard ABR connections, the rate control feature license is checked back into the license
pool and becomes available for other cards.
There are three ways to add licenses to the license pool:
•
•
•
To explain these cases further, if a license is purchased at the same time as the MPSM card, the license
can be programmed on the MPSM card. When a license is programmed on an MPSM card, the license
is unavailable to that card and all other cards in the switch. To enable use of the license, it must be moved
to the switch license pool, which is a database on the PXM card. The MPSM movelic CLI command is
used to move programmed licenses from MPSM cards to the PXM license pool.
If you want to add licenses after receiving an MPSM card, you can purchase them using the Cisco.com
website. Licenses that are purchased on the web site can arrive in the form of an encrypted key in an
E-mail message or a file that contains an encrypted key. The PXM cnflic command is used with the
encrypted key or license file to add licenses to the PXM license pool.
When a license is checked out, the switch records the assignment of the feature to a card and enables the
feature on the card. The license remains in the license pool until explicitly removed. The only way to
safely remove a license from the pool is to explicitly transfer it to another switch.

The Switch License Pool
If the license is purchased with the MPSM card, use movlic to move the license(s) from the MPSM
card to the PXM license pool.
If the license is purchased alone—without the MPSM hardware, use cnflic to add the license(s) to
the PXM license pool.
If you want to move a license from one MGX node to another MGX node, you must transfer the
license.
