There is a fault with an LTM device load balanced trading application that resides on directly connected VLAN vlan-301. The application virtual server is
10.0.0.1:80 with trading application backend servers on subnet 192.168.0.0/25. The LTM Specialist wants to save a packet capture with complete payload for external analysis.
Which command should the LTM Specialist execute on the LTM device command line interface?
To save a packet capture with complete payload for analysis, the command must include the '-s 0' flag to capture the entire packet. The '-nni vlan-301' flag specifies the interface and captures traffic without resolving names, which is necessary since the application resides on VLAN vlan-301. The complete command is 'tcpdump -vvv -s 0 -nni vlan-301 -w /var/tmp/trace.cap 'net 192.168.0.0/25'' which ensures that all relevant traffic on the specified subnet is captured in full detail for analysis.
D - Correct. -s flag specifies size of packet to capture, setting the 0 will capture entire packet. -i flag specifies interface/vlan https://my.f5.com/manage/s/article/K411
