session offfload and flow basic

 

When we do session offload then PCAP can not capture the session offload traffic .

if i am also doing flow basic on that then flow basic will not be impacted by session offload?

Hey @MP18

 

Correct. A flow basic will not be able to capture any traffic if it has been offloaded so if you're wanting to do a flow basic for any SSL traffic, for example, then it is important to disable session offloading for the duration of your capture/testing.

 

Disabling session offloading is a global setting and will add some additional overhead processing to the dataplane so it is important to remember not to run a flow basic if the dataplane CPU is high.  The traffic itself will not be impacted by session offloading being disabled. Other important factors to remember are:

 

- Always apply filters when doing any sort of traffic capturing

- Do not attempt to modify the filters whilst logging is enabled; first, disable logging then modify your filters.

Great reply!

One last thing if i enable PCAP filters and do session  offload will it offload only sessions filterd in pcap 

 

or it will offload all the traffic?

Hey @MP18


Session offloading is a global setting meaning it will take effect on all traffic.
