Hi all,
I have a quick question...
I enabled trunking for all vsans and created a port-channel. I want to use this port-channel for all my vsans.
Does it matter in which vsan I add my port-channel?
If it doesn't matter why can I assign a port-channel to a vsan?
Cheers,
Mike

Mike,
It should be the same configuration on both sides for the port-channel to come up. The reason why you can assign a port-channel to a VSAN is that if you are using an E port then it depends on the matching port-channel VSAN to come up.
TE Port functionality is specific to MDS for enhanced ISL capabilities. E ports can be used for non-cisco switches to make the trunk work seamlessly as an E port.
You can refer to the following for more info:

Hope this helps.

There are 2 schools of thought on this.
One: leave the port-channel in the default vsan number 1. If you have devices also in VSAN 1, you may want to the next option.
Two: create a unique VSAN that only contains the port-channels and TE ports. This VSAN should have no end devices in it.
There really is no technical difference. Some folks like the management aspect of keeping the port-channels and TE ports in separate VSANs so that you can view all the ISL ports by looking at a specific VSAN.
Hope this helps,
Mike
