as the above post incines I think you are pirated by Tuam Phan at http://www.4salesbyself.com

in fact everything on http://www.4salesbyself.com seem to originate from other sources on internet.

Cheers and good luck!

Just to follow up on the mixing and matching of dual and single connected FEX's. You most certainly can intermix them. We just went through this with trying to create a VPC down to our Isilon nodes while dual connected. The 5010's only have 6 FEX's currently configured and we have opt'd to single connect (odd numbered fex on one 5010, evens on the other). Works fine.

Actually, we will be going through a migration to single connect all the FEX's.

I don't think my post has anything about ONLY doing 1g or 2g from the 5k to the 2k's - in fact, it assumes that all the links from the 5k to the 2k are 10g. It should be for links from the host to the 2k. The issue has to do with the port-channel options available with a 2148t in a dual homed vs. single homed down to the host - not upstream to the 5k. I'll read it again to see if I mis-stated something or if I can clarify, it has been a bit since I posted this one.

Obvisously you as missing something here.
Why would you take a 5k and connect it to a 2148 with only 1g or 2g at that. Remember the 2k's are essentially 6748's in a box using the Fabric extender protocol to act as a backplane to the 5k (Supervisor) in a box. This is why it is only recommended to use the 10g uplinks, and I know the 10g ports can be channeled. Look at it this way if your using a 2148T you are over subscribed 48:1, now this is something I don't want to explain when packets start disappearing.
