Chassis Aggregation

This topic is to discuss the following lesson:

Hi Rene
Does Chassis aggregation also combine Chassis supervisor together, Ex, Chassis Aggrgation CPU = chassis1 cpu + chassis 2 cpu ?

Hello Heng

Chassis aggregation will allow you to view two 6000 series switches as a single logical switch. If the supervisor goes down on one chassis, the supervisor of the other chassis will NOT take over. Each supervisor is responsible for supporting the cards on the local chassis. For this reason, we often have two supervisors per chassis in order to provide the necessary redundancy even in this case.

The major advantage of the chassis aggregation technology is, as Rene states,

β€œThe two core switches will act as a single switch to the outside world when it comes to control plane protocols like ARP, spanning-tree, EtherChannel and routing protocols. Information like MAC addresses in the MAC address table are synchronized between the two switches.”

I hope this has been helpful!
