UDP Virtual server (port 162) not working on version 14.1.0.1 Build 0.0.7 Point Release 1

Hi I have set up a UDP standard Virtual Server with 1 member, listening to port UDP 162. The purpose of this VS is to balance SNMP traps to the pool members.

The VS is not working. Traps sent to the VS are not sent to the members. I have done a very similar set up with another F5 deployment running an older version. So I'm not sure what the problem is.

Is anybody aware of a bug in the software?

This is my VS config: ltm virtual PDC-GGRDR-SNMP-VS { creation-time 2019-04-09:15:51:34 destination 10.51.1.200:snmptrap ip-protocol udp last-modified-time 2019-04-10:07:37:34 mask 255.255.255.255 pool GGRDR-SNMP-Pool profiles { udp { } } source 0.0.0.0/0 translate-address disabled translate-port disabled vlans { vlan511 } vlans-enabled vs-index 4 }

Pool: ltm pool GGRDR-SNMP-Pool { members { SILV-GenGET-Reader:snmptrap { address 10.100.0.18 session monitor-enabled state up } } monitor gateway_icmp }

Thanks! Mick
