I hope you're all doing well.
Whether it's possible to take PCAP from gateways, if possible, please let us know the procedure.
Gateway Model: X2020
Hi Jagadesh Kumar,
Thank you for the post, you can follow the below steps,
To record a pcap file with tcpdump:
Enable TCP dump: 1. tcpdump_on
2. run tcpdump as usual
Step 3 is very important, if it is not be done, the gateway performance might be affected until you will run this step (reboot will also stop it). Record a pcap file with tcpdump: Once you're logged in as the root user run the following command:
tcpdump -i ethX -s0 host 22.214.171.124 and port YYY -w /var/tmp/name.pcap
Here is an example: tcpdump -i eth2 host 10.10.10.1 and host 126.96.36.199 -w /var/tmp/case001.pcap
