LACP portchannel between 6500 and CRS isn't working

Hi,

We have some 6500, 7600 and CRSs in our network. Now, we are setting LACP etherchannel  CRS <--> 7600 and CRS <--> 6500. The first type are working ok but the second type (CRS <--> 6500) isn't working. The configuration is the same as the first type but the 6500 says:

*May  7 16:41:52.715: %EC-SP-5-L3DONTBNDL2: Te4/1 suspended: LACP currently not enabled on the remote port.

*May  7 16:41:53.127: %EC-SP-5-L3DONTBNDL2: Te4/2 suspended: LACP currently not enabled on the remote port.

This is the config of both equipments:

++++++++++CRS+++++++++++++

interface Bundle-Ether200

interface TenGigE0/1/0/2

bundle id 200 mode active

!

interface TenGigE0/1/0/3

bundle id 200 mode active

+++++++6500++++++++++++++

interface Port-channel200

interface TenGigabitEthernet4/1

channel-protocol lacp

channel-group 200 mode active

!

interface TenGigabitEthernet4/2

channel-protocol lacp

channel-group 200 mode active

Looks like the 6500 can't see the LACP packets from CRS.

I appreciate the help you can give me!!

Hi Diego,

Check cable, tranceivers, turn on UDLD. See if you have any layer 1 issue.

Hi Lei,  Thanks for the reply. We already checked layer 1. The links works fine if they are outside the port channel.

as per the logs, it looks like the 6500 is not recieving any LACP  packets from the other end / there is some issues in local end and the  LACP packets are not processed. well..

can you lemme know what is the running image version and the Sup model?

Hi Furose, Thanks for the reply,  we have sup720 3bxl with 12.2.33SXJ5

what about swapping the cable nd if possible the link itself? can you connect the working link CRS<---->7600 to CRS<----->cat6k adn vice versa?

this way we can eliminate L1 issue.

Hi Furose,

Thanks for your reply. We tested and discarded the link and another L1 elements. Then, we changed the ES+2TG3CXL (where the links was configured)  by WS-X6704-10GE module and the eterchannel works fine with the same config.

Hey Diego,

Nice to know that its working fine now. Mind running diagnostics tests on the module by configuring the boot diag level to complete? could be a hardware issue. or probably the moduel reset could have fixed as well ;-)
