Standby Status Provider Shows "Listen" state for some non-Active members

Technote (FAQ)


Question

Why does the Standby Control status show a non-Active group member as being in the Listen state on IBM WebSphere DataPower SOA Appliances Version 5.0+?

Cause

If the interface is in the Listen state, it is listening to Hello messages, but is not sending any Hello messages.

It is neither the Active or Standby member of the group, but is monitoring in case a failover is needed.

Prior to 5.0 Firmware, the Standby Control status provider would show all non-Active members as being in "Standby" state.

Answer

In the 5.0 Firmware Standby Control status provider, there should be exactly 1 Active member and exactly 1 Standby member, with any additional group members showing the "Listen" state.

The actual underlying states have not changed across releases, only the status provider has been enhanced to be more specific.
