Tcpdump commands not working on SN2410


I am following the following reference for using tcpdump on the SN2410 switch.
Mellanox Interconnect Community

The following command doesn’t work on the switch :

tcpdump -i eth1.0

Can you please tell me if this document is targeted for a particular switch or is it something wrong in my configuration?

Thank you,

The article was for L3 ports only.
In this case - you have a L2 port (in switchport mode)
Please try the below

tcpdump -i ethsl1p1
In any case the traffic you will see - will be only cpu ingress/egress traffic, not traffic forwarded by HW

and if it’s not working - please provide the switch software version:

It doesn’t work. Here are the details:

ualloc-mlnx2 [standalone: master] (config) # tcpdump -i ethsl1p1
tcpdump: ethsl1p1: No such device exists
(SIOCGIFHWADDR: No such device)
ualloc-mlnx2 [standalone: master] (config) # show version concise

Thank you,

This version is tool old.
Plrase try using 3.9.x or 3.10.x


Can you please provide me a link to the instructions to upgrade the version?
