packet capture on LTM with different partition

Please note that partitions on the BIG-IP platform are used for administrative seperation only. Route domains however can be used to isolate network traffic. When using tcpdump to capture traffic in a non-default route domain, F5 recommends that you run the tcpdump command from the default route domain (route domain 0), and specify interface 0.0.

For example, the following command captures traffic from all VLANs in all route domains when invoked from the default route domain:

tcpdump -ni 0.0
