Port Channel question

[Mike Mott]

I have a 2960 stack with 2 WS-C2960S-48FPD-L distribution switches running c2960s-universalk9-mz.150-2.SE2.bin.

I then have three stand alone 2960S-48 access switches running the same code.

I will have two ten Gig uplinks in a port-channel back to a 6500. I have this config. however 

I would like to have port-channel between each of the distribution switches in the stack and each of the stand alone access switches.

So as an example:

distribution switches port 1/0/48 and 2/0/48 in port channel 1

access switches 1/0/51 and 1/0/52 in channel-group 1 active

I am looking at doing this for aggregation as well as redundency.

Does this sound practical?

Mike,

YES,

Etherchannels (Port Channels) are by nature aggregators.

So basically  you are getting double bandwidth as a channel.

If you run them without channelling then 1 link will be

blocked by spannining tree resulting in redundancy  like active/standby
