LTM address conflict detected
Hello we encountered an error on our LTM v11.6.0 HF4 active-stanby regarding address conflict which we're suspecting that's causing the unit to fail processing traffic from time to time. We encountered this error in the LTM logs:
address conflict detected for 10.81.17.75 (00:23:e9:8f:3e:02) on vlan 1701
10.81.17.75, as I found out is used for SNAT while vlan 1701 is the egress vlan. I do not know what's causing the conflict. Also noticed that the one of the standby unit's trunk is down even though all interfaces are up. Found a related SOL article(https://support.f5.com/kb/en-us/solutions/public/14000/100/sol14104.html)) but I doubt it is the problem since no conflict in device group setting. Would like to know how can this be fixed? Thinking about changing the SNAT IPs if it could solve the problem but we can not just change anything from the unit immediately unless we fully understand the issue and how to fix it.
