Ping times out on ASA Active/Standby Stateful Failover Config

I have two ASA5510 configured in Active/Standby stateful failover. I noticed that when I connect via VPN and ping a server on the corporate LAN and disconnects one of the Active ASA Inside or Outside Interface, the ping times out for about a second. This happens when the ASA is switching from Active to Standby.

Find below my failover config:


interface Ethernet0/0

nameif outside

security-level 0

ip address PIX-OUTSIDE standby 62.x.x.205


interface Ethernet0/1

nameif inside

security-level 100

ip address PIX-INSIDE standby 192.168.x.253


interface Ethernet0/2

description LAN Failover Interface


interface Ethernet0/3

description STATE Failover Interface


interface Management0/0

nameif management

security-level 100

ip address




failover lan unit primary

failover lan interface failover Ethernet0/2

failover key cisco

failover link state Ethernet0/3

failover interface ip failover standby

failover interface ip state standby

no monitor-interface management

Is there any timer I can adjust on the ASA to prevent VoIP calls from dropping when the ASA switches from Active to Standby?

Telnet to active device and then initiate a failover , your session should not be disconnected.

I dont think that u need to adjust the timer for voip becoz secondry is gathering all sessions.

however you can give priority to voip in ASA.
