A question again !
I have two PIX 515-E, one with UR licence and the other with FO licence only.
Both serial cable (not really serial but you understand me) and ethernet cable are connected for the failover.
Why?? Both are near. When I do a sho faiover i see that ethernet is : N/A.
The guy who configured before me this device said me that it was cisco who told him to make this confiugration with both cable.
Can you explain me why? To maintain session??? I belived that it's only when you use serial cable that your session is saved.
Thank you a lot for your answer.
There are two parts to failover. One is required, the other is optional. Let me explain:
1) Serial vs. LAN failover (required)
2) Stateful failover (optional)
For #1, you must choose to use the serial cable or an ethernet interface to send the failover configuration information to the peer.
For #2, you can optionally enable stateful failover (which is an ethernet interface only) and this replicate the state of the connections/xlates/etc from the Active to the Standby (high recommended so that failovers do not have any impact on users).
If your PIXes are close by, I would suggest using Serial failover along with stateful failover (for state replication). This may be what you have configured. If you want to send the output of :
show run | inc failover
We can have a look.
Hope it helps,
