The collector VM must be reachable from F5. If the collector VM is unreachable from F5, you must create a route entry for the collector.

To check if the collector VM is reachable from F5, you must run the following command: ping <collector-ip> -I <virtual interface> from the Command Line Interface (CLI). If the collector is unreachable form F5, you must create a route entry for the collector.

For example, 
admin@(localhost)(cfg-sync Standalone)(Active)(/Common)(tmos)# ping 10.153.191.116 -I VLAN301
PING 10.153.191.116 (10.153.191.116) from 10.115.30.50 VLAN301: 56(84) bytes of data.
From 10.115.30.50 icmp_seq=1 Destination Host Unreachable
From 10.115.30.50 icmp_seq=2 Destination Host Unreachable

Procedure

  1. In the F5 console, click Main > Network > Routes > Add.
    The New Route screen appears.
  2. In the Properties section, configure the route entries to send the flow records from F5 to the VMware Aria Operations for Networks collector through the virtual server.
