Error description

  • v3.9-GA, FP1 & FP2 -Platform independent

Two issues:
1) When a duplicate IPAddress with same lingertime seen by the
Poller, it stops polling either IP.

2) Upon hitting above scenario, if the lingertime changes for
one of the entity (say InterfaceA with LingerTime 2 and
InterfaceB with LingerTime 3) as a result of discovery, poller
should resume polling, but it isn't.

Local fix

  • To workaround problem #2  there are two options:
1) Unmanage and remanage that interface with higher ligertime.
OR
2) Disable and Enable poll policy that is polling those
interfaces.
