Re: CSS11503 service failover for server with 2 NICS
I think this will be an adjustment on the Server and not on the CSS. The Server Admin must configure the DUAL NIC in MULTIPATH (Active-Standby Mode).
Both NIC's will be bonded to a single IP Address and single MAC-Address.
When Primary NIC is enable, it will be the one to do the ARP. CSS will detect the Primary NIC's IP/MAC address on the it's receiving interface. When Primary NIC goes down, CSS detects a link failure and removes the ARP entries on the interface. At this time, the Standby NIC will do the ARP to let CSS know of the correct interface.
On the other hand, if you want to make it harder for yourself, you need to configure
4 services for your web service
server161 - server1 pri NIC
server164 - server2 pri nic
server261 - server1 b/u nic
server264 - server2 b/u nic
With the keepalive on the each services, server161 and server261 services will be
detected (alive) while standby NIC is in down state. The Content rule only forwards the data to the services in Alive State.
NOTE: Just ensure that the B/U NIC doesn't ARP while in Standby Mode. (do a "sh arp" to verify).
