ACE in Bridge mode

ssh · ‎01-30-2007

I am going to get ACE blades in a week time frame. Currently I run CSMs in bridge mode with inter chassis failover. What is Cisco's recommendation regarding ACE and layer 2 mode? Also is there anything I need to carefully consider especially layer 2 and spanning tree wise when ACEs are running Inter-chassis Active/Standy mode?

Any tips/URls are welcome.

thanks,

Use the arp learned-mode enable command in configuration mode

By default, the ACE learns MAC addresses from host responses. To enable the ACE to learn MAC addresses on all traffic, use the arp learned-mode enable command in configuration mode. You configure this command per context. For bridged interfaces, this command allows them to learn ARP information from ARP packets; normally the ACE forwards at Layer 2 without learning any ARP information.

The syntax for this command is:

arp learned-mode enable
