Need to capture VLAN traffic on/through vCMP guest LTM

If you want to see both sides of the traffic, you can use: tcpdump -i 0.0

0.0 captures on all VLANs and would show both sides of the traffic regardless of VLAN. Capturing to a file is also helpful, as you can then download and review in Wireshark. It will also capture traffic that may not be arriving as expected. On a production unit I would strongly suggest that you filter as narrowly as possible to avoid overwhelming the unit. You may wish to verify that you can get out from the guest to make sure that you don't have another device responding to the client.
