debug packet capture not working

Anonymous — Mon, 11 Sep 2017 18:54:00 GMT

Hi,

Just trying to run a debug packet capture on the following:

Stack of 4 x X450G2-48P-10G4, running version 22.2.1.5-patch1-4

As per the following GTAC articles:

https://extremeportal.force.com/ExtrArticleDetail?an=000079573 (This article is slightly wrong in that I had to use 'ports' not 'port' as shown.

https://extremeportal.force.com/ExtrArticleDetail?an=000082238

Have tried the following commands:

debug packet capture ports 1:21 on vlan B20_23-L-GND-Voice cmd-args "-c 1000"
debug packet capture ports 1:21 on count 1000

These both take OK but the only file produced in the /usr/local/tmp is a file called capture.log

When I look at that file capture.log it contains the following:

tcpdump: can't add port 10015 on packet socket: Protocol not available

Maybe there is some restriction, perhaps on a stack, model or version that is causing that issue that I've missed?

Appreciate any help in advance.

Many thanks

Hi Martin,

This appears to be related to the "CR xos0066839 : When debug packet capture is enabled for a port, pcap file is not created in internal-memory". This CR has been fixed in EXOS 22.3.1.4.
Please let us know if you have any other questions.
Thank you.

Best regards,
Andrew
