hi ,

I have a cisco asa 5510 with security plus license in Live enviroment .

I need to add a secondary firewall .

I was planning to do in active /standby mode for failover .

But i have a doubt , when i do "show version " on live asa output says Active /active failover , does this means that i can only configure failover in active/active mode not in active/standby (which i want to do )?

please advice

sh ver

If you have active/active license, you can configure active/standby as well, but if you only have active/standby then you cannot configure active/active failover.

This is means it supports Active/Active Failover as well, So your Firewall now supports both Active/Standby and Active/Active Failover configuration.

Hi Amit,

active/active failover is done by creating contexts, you can check it by:

show failover

this output would show you if it is active/standby or active/active.

Read through this configuration docs as well, it would help:

Hope that helps,
