8Gig Port Channel between two 6509s

Hey all,

I have two 6509s that I'm trying to configure an 8 Gig trunk/port channel. I have an 8 port fiber module in slot 3 on both switches. When I use the following command: "set port channel 3/1-8" on it seems to take the command, but if I do "show port channel" it shows two groups:

3/1-4

3/5-8

Is there a limit as to how many gigs a port channel can be? If not, why does it split it like this?

I should also note I'm using dot1q for the trunks using Auto mode on one switch and Desirable on the other.

Thanks,

Scott

There used to be a limit on the cards . But i thought they had gotten around that on the 6500 series. Do a "show port capabilities 3/1 and then 3/6 and see if there is restrictions on channeling on your cards.

I did a show port cap on the interfaces and I didn't see any sort of restriction. I decided to run the command again 'set port channel 3/1-8 on' and for some reason it seemed to work this time. Not sure what changed, but it's working now.

Thanks for your help!
