Is a primary and standby IP address required for EACH interface on the firewall for failover to work properly?
I have setup a pair without having a standby IP on all interface, and only having it on the stateful failover link, and failover seems to work fine, however SNMP graphing does not.
I am being told that failover requires a standby on each interface, but this is the first time I am hearing this, so wanted to see other users experience.
The only problem I am seeing is when a failover pair does not have a standby IP for each interface, that the graphing does not work.
Thanks for any comments.
