tcpdump of UDP traffic

If the traffic is traversing the LTM, even via a forwarding virtual server, it can be captured by tcpdump. If you look at the tcpdump man page (man tcpdump from the cli) you get a list of all the possibilities. For starters, you can look at the rtsp traffic (assumed default port) on the physical interface, or on a vlan interface:

 

 

tcpdump -i 1.1 udp port 554 -s0

 

tcpdump -i Internal udp port 554 -s0

 

 

If you want to capture udp port 554 even on the internal loopbacks, you can use interface 0.0. Any broadcast traffic in a vlan that the LTM participates will also be viewable via tcpdump.
