Revoke a License

Revoke a license on the switch if you need to transfer the license to a different switch.

You can permanently remove a license, which allows you to transfer the license to another switch. This should only be done when preparing to return a defective switch for a replacement switch (RMA).

About this task

The no license command invalidates the feature license and generates a revocation certificate, which is the first step to releasing the license entitlement back to the license entitlement manager (LEM). The revocation certificate is contained in a file where the first part of the file name is the switch serial number and the file extension is .rvk.

Procedure

Enter Global Configuration mode:

enable

configure terminal
Revoke a license:

no license <10G WORD<1-64> | macsec | premier>

Note
Beginning with Fabric Engine 9.0, 5320 Series switches no longer require a license to operate SFP+ ports at full 10 Gbps. Use the 10G WORD<1-64> parameter to revoke a previously installed license.

Example

Revoke the Premier license.

Switch:1>enable
Switch:1#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Switch:1(config)#no license premier
