Known Affected Versions:

Opened: Dec 23, 2020

Severity: 4-Minor


The tmsh run /sys failiover standby device <device> command fails and returns an error if no traffic-group is specified: Syntax Error: There is no failover device with a name (/Common/bigip2.localhost).


You are required to specify all the traffic groups you want to failover to a peer.


Two or more BIG-IPs configured with high availability (HA)


For each traffic group that you want to failover to a peer run the tmsh run /sys failover standby. For example if you want to fail over both traffic groups traffic-group-1 and traffic-group-2 to failover to bigip2.localhost, run the following: tmsh run /sys failover standby device bigip2.localhost traffic-group traffic-group-1 tmsh run /sys failover standby device bigip2.localhost traffic-group traffic-group-2 If you want the device to be standby for all traffic groups but you don't care what device takes over as active, run the following command (note there is no traffic-group nor device): tmsh run /sys failover standby
