ACE failover working not assuming IP address

[networker99]

I have 2 ACE's configured in active/standby and the failover works, but the standby does not assume the IP address of the failed primary.. so all the webserver traffic stops working

That's expected. In a HA configuration, you may config an IP alias i.e.

interface vlan 536
  ip address 192.168.6.99 255.255.255.0
  alias 192.168.6.100 255.255.255.0
  peer ip address 192.168.6.98 255.255.255.0

so basically the active module will have ownership about the alias IP.

Indeeed in the example above, the .99 IP will remain only assigned to the local box, and the .98 to the peer box.

Have a look here if you wish:
