No more CMP on Nexus 7000 next-generation supervisor modules Sup2 and Sup2E

Connectivity Management Processor (CMP) is like an embedded terminal server dedicated for a single Nexus 7000 data center switch. I personally like this feature because we do not have to prepare another set of terminal server just to monitor the console output while we reboot the switch.

However, starting from Supervisor 2 (Sup2) and Supervisor 2 Enhanced Module (Sup2E), CMP hardware is removed from supervisor module itself.

I am not sure whether this feature will come back in the future or not. For the time being, we will have to prepare terminal servers or reserve asynchronous serial ports for Nexus 7000 switches administration.
