unable to configure stateful failover in Cisco ASA

[ahmad82pkn]

Hi, i was trying to configure Cisco ASA pair in Stateful Failover Active/Standby.

When i try to configure Stateful link i get below error, What to do ?

i want to share Failver link and Stateful Failover on same single Ethernet link

Current config:

failover
failover lan unit primary
failover lan interface FOC Ethernet0/2
failover interface ip FOC 10.10.10.1 255.255.255.252 standby 10.10.10.2

When i try 
Configuring Stateful failover:

ASA1(config)# 
ASA1(config)# failover link STATEFUL
Please specify the interface/vlan when not sharing the failover lan interface.
ASA1(config)# failover link STATEFUL e0/2
ERROR: interface already in use as failover interface
ASA1(config)#

Hi.

the problem you are having is that you specified two different names for the same interface.  If you keep the stateful name the same as the failover interface, it should work.

for example:

Current config:

failover
failover lan unit primary
failover lan interface FOC Ethernet0/2
failover interface ip FOC 10.10.10.1 255.255.255.252 standby 10.10.10.2

then add:

failover link FOC

the message you got earlier was because you named it stateful and that implies its using a different int.
