Hi,

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?

Here are the details of my ethernet port:
Eth1/1:
Admin state : Enabled

Last change in operational status: 1d and 15:33:40 ago (7 oper change)
Boot delay time : 0 sec

Mac address : ec:0d:9a:5f:d8:3c
MTU : 1500 bytes (Maximum packet size 1522 bytes)

Actual speed : 10 Gbps
Auto-negotiation : Disabled
Width reduction mode : Unknown
Switchport mode : hybrid
MAC learning mode : Enabled
Forwarding mode : inherited cut-through

Telemetry sampling: Disabled TCs: N\A

Thank you,

Hi
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:
