ACE Context Deactivation

[Marvin Rhoads]

Hello Netpros,

I am migrating off of an ACE-20 module (running A2(1.6a)) with admin and three contexts in favor of another load balancing platform. (I need IPv6 now and Cisco isn't delivering it.)

So I want to shut down all of the load balancing VIPs in a given context and bring up that group of servers on the new platform. It appears the easiest way is to:

a. back up the current contexts each to a text file (checkpoints won't suffice as my next command would delete the checkpoints for a given context).
b. from admin context, configure "no context [context_name]"

In the event that a rollback is necessary, I just recreate the context (including any context mode commands) from configuration mode within admin context and then changeto the context and paste in the backed up configuration in one fell swoop.

Comments or suggestions?

Thanks in advance.

Hello ,

I might try :

- configure the new balancers with shut down interfaces

- login into the old balancer - admin context - changeto context that is migrated , shut down the interfaces

- no shutdown the interfaces of the new loadbalancers.

Rollback :

- shutdown interfaces of the new balancers

- no shutdown - via the same way = admin context -> changeto context that is rolledback , no shutdown of the interfaces

Thanks for the suggestion. I'm planning on the bit with the new load balancer already (preconfigured with non-management interfaces shut down).

I was not sure in the ACE if simply shutting down the VLAN interfaces on the contexts that serve up VIPs would suffice to remove all traces of the VIPs from the network. I suspected it would since those interfaces are the ones that either serve the VIP IP addresses themselves (on the outside) or poll the serverfarm hosts (on the inside).

Update - your suggestion worked fine, Dan. Rated your answer as "Correct". Thanks again.
