Anybody has experience with packet capture on the Juniper srx240? I see that there is two ways to do it, cli vs j-web. It looks like jweb is easier. Any performance issue while running packet capture on the srx? Thanks

This is from KB above:
with the firewall filter, the amount of traffic to be capture can be restricted, and it is less CPU intensive, as compared without filters.

Depending what you define the filter it would be performance intensive.

Thank you.

All I want is to see what traffic is going through 1 interface on my srx. Do I need to do the cli way with firewall filter?

I use the packet capture feature with jweb. I downloaded the pcap file and I don't see the source and destination IP address. Any ideas? Thanks

Better to use pcap feature with cli as you get to configure filters and have more granual control.

The steps are listed in the JTAC KB link posted above.

Thank you.
