Failover IP Address

Why do the Failover IP Addresses in a cluster use include the management IP addresses and the High Availability addresses. Woudlnt it make more sense to listen only on the HA since it is directly connected and doesnt have to traverse the management network?

 

Also, since it is listening on two vlans (networks) is there a precedent to which one it listens on? In the gui it's lists the management above the HA? Thanks.

    "F5 recommends that you configure network failover to communicate over the management network, in addition to a TMM network. Configuring network failover in this way creates a reliable failover communication channel while the system initializes, and before the TMM network connectivity channels are fully established."

     

    I don't think there is a precedence here, just rather redundancy of the failover mechanism.

    On a more practical note, it doesn't really matter how long you set the wait to go active timer. If you don't have the management interface listed, then you will probably go active on reboot every time... (Before the connection table syncs).

     

    Oh.. For v11, you can struggle to get the device group to sync if the management interfaces are not listed as well... The errors can be very frustrating there... And it's not consistent.
