etherchannel / port channel issue

[pgyogeshkumar]

I have configured a Layer 3 etherchannel with just single port configured at both ends. Although the port channel and the physical interface at both ends are up. I am unable to ping the far end.

Ip route says its locally connected.. and the traceroute doesnt even goes to next hop.

Can you please suggest what could be causing the issue ?

Hi,

An EtherChannel should definitely work even with a single physical link active. Is it possible to post the configuration of the Port-channel interface and the related physical interface from both switches?

Best regards,
Peter

Hi Peter I will try with the points Vinit mentioned and if it still doesnt work I will post the config here.

Apologies for bit late reply

What device is it between which you are forming the port-channel. Could you please share the interface and port-channel configuration from both devices.

Also, could you please perform the following test and share the output from both the switches below:

SW1------SW2

++ On SW1, capture show ip traffic | in echo command multiple times and verify if the echo counters are stable or not

++ If the echo counters are stable, then from SW2, ping SW1 IP. 

++ After the ping is done on SW2, go back on SW1 and verify the show ip traffic | in echo command again. Verify if the echo received counters have incremented and if echo-reply sent counters have incremented or not. 

This will help isolate the direction of the problem.

Regards
