Hi,
Wondering if anyone has com across this problem.
We have a 6513 which had 2x 8port (WS-X6708-10GE) 10GB modules one in slot 10 and another in slot 12. Between this two modules we created a 4 port trunk 40GB (2 ports in each module) between the 6513 and a Nexus 7018.
Yesterday we swopped one of the moduless for a 16 port 10GB (WS-X6716-10GE) and cannot trunk between the two cards. Only 2 ports work in either one or the other.
Seems because of the difference between them (DFC3CXL & DFC3C). Taking a look at the logging we noticed something to the fact of incompatability QOS feature between them.
This is what we have installed;
sh module

Never mind I found the solution.
And I meant "Cannot create etherchannel.." not trunk.

Hello Fernando,
as it may be useful to other people, may you post your solution to this issue?
Is it related to dedicated / oversubscribed mode in WS-6716 linecard?
This can give the whole story to forum readers
Best Regards

LOL.
I apologise. I am waiting to test first. Once our cabling team installs a new fibre to the core I will able to test but I´m pretty sure it has has to do with oversubscripotion mode.
The WS-X6716-10GE module has an ingress queue 1p7q2t (oversubscription mode ) whereas the WS-X6708-10GE has 8q4t.
Hence the reason for getting the following;
%EC-SP-5-CANNOT_BUNDLE2: TenGig10/1 is not compatible with TenGig12/1 and will be suspended (qos-card types of TenGig10/1 do not match TenGig12/1)
.
The solution will be to configure "no mls qos channel-consistency" in port-channel interface.
