Releasing a port from a POD set

Once a port has been assigned to a Dynamic POD license port set, it remains licensed (or "reserved") until you remove the port from the port set. You remove a port from the port set by releasing the port with the dpod release command. Releasing a port removes it from the Dynamic POD license port set; the port appears as unassigned until it comes back online.

To prevent a port from coming back online and taking a POD assignment, disable the port and save the running configuration. This action will disable the port persistently.

A port POD assignment can only be released if the port is currently offline. Use the shutdown command to disable the port or use the chassis disable command to disable the switch if you plan to release multiple ports.

Enter the global configuration mode by issuing the configure terminal command.
Select the interface for the port that you wish to disable using the interface slot/port command.
Enter the shutdown command to take the port offline.
Enter the exit command to return to the global configuration mode before you release the port.
Enter the dpod release command to remove the port from the POD license.

Enter the exit command to return to the global configuration mode before you reserve another port.

device# configure terminal
Entering configuration mode terminal
device(config)# interface 0/15
device(conf-if-te-0/15)# shutdown
device(conf-if-te-0/15)# exit
device(config)# dpod 0/15 release
device(config-dpod-0/15)# exit

Enter exit to return to privileged EXEC mode.
Enter the show dpod command to verify that the port is no longer assigned to a POD set.
Enter the enable chassis command to bring the switch back online.
Save the configuration changes.
```
device# copy running-config startup-config
```
Note
Do not release a port unless you plan to disconnect the optical link or disable the port persistently. If you leave the link in a state where the port could be brought online, the POD mechanism will detect this unassigned port and attempt to reassign it to a port set.
