L2 Etherchannel Port Suspended issue

dc-csa-blr
Level 1
Level 1

Hi All,

 

We're using 2 P2P link from different providers ( one 30 Mb and second 20 Mb) from Main POP to Remote POP.

We required load balance between both the P2P links with failover, but one of the port in suspended mode while channel-group apply.

Please advise me to fix the issue and we are able to achieve and use with load-balance via etherchannel.

 

Thanks in ADV,

Here are the questions:

1- Does the link comes up individually when connected? If yes

2- Shut down the ports both the end.

3- Configure the port-channel first then configure the ports accordingly and then do no shut on the physical ports.

 

Kindly revert back with the update after this.

Hi Inayath,

 

Thanks a ton,

 

Now it's working
