Cisco Access Point - Debug, PCAP

RS19 — Mon, 05 Jul 2021 19:55:56 GMT

I am having Cisco AP model AIR-AP1852I-Q-K9

I am going to run debug & capture the logs as per the below manual.

https://www.cisco.com/c/en/us/support/docs/wireless/catalyst-9120ax-series-access-points/215413-configure-internal-wired-packet-capture.pdf

According to the manual, the below file is going to be created.

# debug traffic wired ip capture % Writing packets to "/tmp/pcap/2802_capture.pcap0" #reading
from file /dev/click_wired_log, link-type EN10MB (Ethernet)

Question is how can i check the file in /tmp
Is there any way i can access the path /tmp ?

If so how to access it ?

Once you SSH into AP, then you should be able to see those directory / file paths.

"show flash" should tell the file system in flash.

Once you issue that "debug traffic wired ip capture" it should automatically write it to /temp/pcap/xxx path. Then you should be able copy it to external TFTP

copy pcap AP70DB.98E1.3DEC_capture.pcap0 tftp 192.168.1.100

Did you try it as instructed?

Thanks,

how can I browse the below path in the AP

/temp/pcap/xxx

I want to go to /temp/pcap and want to check the files stored in the below location.

How can I do that.

Also is there time limit the debug files are stored in the below location.

When I tried to retrieve the file after 3 days, it says the file does not exists.

So wanted to check what is the limit the file exists in the AP.

Will the file gets removed when the AP reboots ?
