Cable Failover with a Lan failover

[myoucef]

Hi,

I know that a cable failover do the same things as a lan failover, and moreover a cable failover can detect a power failure (the lan failover can not do it).

Can we have in the same PIX a cable failover and a lan failover??

Thanks.

cable failover WILL NOT do stateful failover (AFAIK)

yes you can do both cable + lan, and have quick failover + stateful

cheers

I have PIXs with cable failover and an interface dedicated to a stateful failover, I think that the main difference between the cable failover and the lan failover is the distance between the PIX and its failover (the distance is limited with a cable failover).

[davecs]

cable only failover:

6 meters max (cable length)

no stateful failover (ie no tcp information syncronisation)

can detect poweroff from other unit immediately

lan failover:

can have any distance (upto max ethernet distance of course)

statefull failover

must wait ~45 seconds for 3 hello's to timeout before determining other unit is dead.

use both for the best of both worlds - unless you must have your pix's more than 6 meters apart.
