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:
ip address PIX-OUTSIDE 255.255.255.240 standby 62.x.x.205
ip address PIX-INSIDE 255.255.255.0 standby 192.168.x.253
description LAN Failover Interface
description STATE Failover Interface
ip address 192.168.111.1 255.255.255.0
failover lan unit primary
failover lan interface failover Ethernet0/2
failover key cisco
failover link state Ethernet0/3
failover interface ip failover 192.168.200.1 255.255.255.252 standby 192.168.200.2
failover interface ip state 192.168.200.5 255.255.255.252 standby 192.168.200.6
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?
