Traffic Group Failover when Trunk Fails

Hello,   I have a pair of F5 LTMs running as Active-Standby in a traffic group. Both the LTMs have trunks configured from a switch.   What will happen when all the interface in the trunk fails ...

    Hi

     

    You should setup HA-GROUP if you track trunk interface.

     

    HA-GROUP setup should be on each of your device(Active and Standby)

     

    HA-GROUP configuration isn`t syncable feature.

     

    please refer to it.

Hi,

 

Without HA GROUP, the only solution to check if interface is enabled is vlan fail safe or gateway fail safe!

 

Both fail safe features make traffic group to become standby if one interface fails, even if the other appliance can’t become active.

 

HA GROUP allow to manage priority to always have one member up!

 

So in some deployment, I configured trunk with only one interface to enable HA GROUP.
