port channels across slots on a 6500

[sandevsingh]

Hi experts,

we have 2 x 6509-E chassis NOT doing VSS, having a 10g module ( WS-X6708-10GE ) in each chassis. We plan to get another 10g module (same as existing) for each chassis. I was planning to move some ports from the existing module to the new module. 

Question - Is a port channel supported across 2 modules on the same switch? 

thnx

Hey,

Cross module etherchannel is supported as long as physical characteristics of ports match. Do check the QoS properties as well.

Also check the restrictions section as well:

HTH.

Thanks guys, I have exactly two same modules in the chassis, so qos should not be an issue among them.

It is recommended to channel ports on blades with the same queue types.

This behavior can be bypassed  by command.
