Symptom

When using a NetFlow monitor and record configured with L4 port matching, UDP port numbers aren't sent to the collector. Additionally, UDP port numbers don't appear in "show flow monitor NAME cache module NUMBER".

Conditions

Nexus 1000v, L4 port matching configured

Workaround

There aren't any at this time. NetFlow can continue to capture other useful information about UDP flows and the port numbers of TCP flows.
