Unable to Perform Debug Flow

[KayvanRomaezi]

Hello, have a PAN-5050 running 4.1.13, where I am trying to debug flow on.  Followed the steps necessary to turn on flow debugging but I am not seeing anything log to either of the dataplane pan_packet logs files. I've confirmed the settings are in place on both data planes but nothing is logged.  Anyone know of any issues with flow debugging on 4.1.13? 

debug dataplane packet-diag set filter on

debug dataplane packet-diag set filter match <match_criteria>

debug dataplane packet-diag set log feature flow basic

debug dataplane packet-diag set log on

Thanks!

KayvanRomaezi,

There are no reported issues with flow basic debugging being broken in 4.1.13.

If you are not capturing anything in your logs, try the following stesp:

1. Clear all debugging settings

    > debug dataplane packet-diag clear all

2. Set your filter as needed first

    > debug dataplane packet-diag set filter match <match_criteria>

3. Set the filter on

    > debug dataplane packet-diag set filter on

4. It's always helpful to turn off session offloading if your system's current condition can handle it. Check the packet rate on the device and turn session offloading on/off with the following commands:

    > show session info

    > set session offload yes | no

5. Aggregate all logs to a single file prior to running the flow basic

    > debug dataplane packet-diag set log log-option aggregate-to-single-file yes

6. Set flow basic logging on

    > debug dataplane packet-diag set log feature flow basic

    > debug dataplane packet-diag seg log on

As always, use the flow basic debugging tool sparingly as this is very CPU intensive.

Also, remember to turn session offloading back on after your troubleshooting session.

Hope this helps.
