CSS active-active stateful failover

[wmmak]

Dear All,

May I confirm if CSS can do active-active stateful failover? If so, is it any restriction? and any Cisco URL I can refer to?

Thanks a lot.

what do you call active-active ?

There different ways to achieve active-active.

What we can do is 1 vip active on 1 CSS-A and standby on CSS-B and a 2nd VIP active on CSS-B and standby on CSS-A.

But do you really need this ?

CSS can handle quite a huge amount of traffic so I never saw the need for active-active.

The failover can be statefull with CSS115xx not with CSS110xx or CSS118xx or CSS111xx.

Here is a sample config for one-armed mode but you can also have multiple vlans.
