On a Cisco 4507 with Redundant Supervisor Engine IV. Can the Interfaces/GBIC on the standby Supervisor be used or can you only use interfaces on the current active supervisor. I cant find any documentation on this.
The first module on both Supervisor engine would be active. The second module on both Supervisor engines will not be accesible.
