port-channel problem with WiSM

bbxie · ‎01-25-2008

Has anybody met following similar problem:

I put WiSM into slot 3(also tried slot 6) of 6506(sup720-3B, s72033-adventerprisek9_wan-mz.122-33.SXH.bin), using following command to setup the port-channel:

interface Port-channel1

switchport

switchport trunk encapsulation dot1q

switchport trunk native vlan 5

switchport trunk allowed vlan 1-1000

switchport mode trunk

!

int range g3/1-4

switchport

switchport trunk encapsulation dot1q

switchport trunk native vlan 5

switchport trunk allowed vlan 1-1000

switchport mode trunk

channel-group 1 mode on

!

I can use "session slot 3 pro 1" to login to the WiSM, but can't ping WiSM's management IP address from 6506, then I find the port-channel has problem, only G3/1 is up and included in the channel, G3/2-4 are up but line protocol is down, then I found from the log that: "AESUT: %EC-SP-5-CANNOT_BUNDLE2: Gi3/2 is not compatible with Gi3/1 and will be suspended (qos-card type unavailable for Gi3/2 or Gi3/1)". It says those GE port are not compatible for qos-card type, but I checked the configuration, all GE using the same configuration. Don't know why, maybe a bug? Appreciate for any feedback

This seems to be a possible negotiation issue. Try to change the mode of the port (i.e from trunk try to place into access then back to trunk). If this also doesn't works try nonegotiate.

I have the same problem, but it has something to do with QoS. When you disable "mls qos" on the switch, the port-channel will function normal again.

It doesn't help when you configure "mls qos trust dscp" on the port-channel!!!!!

this is a cisco bug:CSCsk43058. you can upgrade IOS or disable mls qos.
