Hi,
Currently l have two ASA 5520's in a active/passive failover scenario. Currently the interfaces for the inside and outside are fixed at 100/FULL.
I want to repatch them into GigE ports setup as Auto Negotiate.
Is there anyway of keeping the connections through the firewall active in this type of scenrio or will l have downtime disconnecting and repatching ? or could l possibly disable failover and reconfigure each ?

Hello,
If they are on a failover cluster, I would do the changes to one unit first ( the secondary) and as soon as the secondary is up and running again I will set it as the active one and then I will make the same changes for the other unit ( the one that was previously the active one)
That should satisfy your needs.

Hey Julio,
How would l reconfigure the Secondary if it is in failover ? would l have to disable failover and then reconfigure the interfaces on the secondary to AUTO and then repatch into the gigE port ?

Hello,
That is correct, but your network will keep being up and running, so there is no downtime.
The problem would be when you come back because now that I analize it more, you will not be able to configure Failover as the interfaces are different. so that would be a problem.
You will have a little downtime, so it would be better to get a maintainance window for your network.

Cheers Julio
I will do the following :
re-patch secondary interfaces into new gigE Ports
reconfigure primary interfaces to AUTO and re-patch into gigE Ports..
As you have said l will experience a small outage window during the period reconfiguration of the Primary..
Thanks for your assistance..

actually could l do a "no failover" on the primary and then reconfigure the Secondary ASA's interfaces and repatch and then make the secondary the Primary "active" and re-enable failover inturn replicating the config to the old Primary ?

Hello,
That is what I though at the beggining, but when you will have on the secondary gigabit ethernet interfaces and on the primary fast ethernet so failover will not work.
