Usage Guidelines

Use this command to keep a port in an active role. It prevents a specified port from being elected to an alternate or backup role which puts the port in a blocking state.

The following describes the port role and state when RSTP stabilizes.

This feature can be enabled on only one STP port in the STP domain.

The restricted port role cannot be combined with this feature.

An active port role (root or designated) cannot be enabled with an edge port.

To disable this command, use the configure stpd ports active-role disable command.

To view the status of the active role, use the show stpd ports command.


The following command enables an active role on STDP s1, port 6:3:
