Nexus 7k and VPC to 3750X

                   I am creating vpc port channels from (2) nexus 7k to 3750x edge stacks.  It looks like I am limited to only 48 port channel ID per 3750x.  Does this mean if I have 100 stacks I will only be able to VPC 48 of them?  I am not limited on the nexus (4096).

Thanks,

Mark

Nexus 7000 with 5.2 code supports 528 portchannels and virtual portchannels

No.  Each switch (as a single unit) or a stack of switches can support UP TO 48 etherchannel.

So if you have 100 stacks of 3750X you can have a minimum of 1 etherchannel or a maximum of 48 etherchannel PER STACK.

Re: Nexus 7k and VPC to 3750X

Eg. If you have 5 switches in a stack with tengig uplink module you can conmect one 10gig port out of each switch connect them to nexus 7000. You can then bundle all these ports in a virtual port channel so each nexus 7000 has 5 member ports in a vpc. This only deducts 1 etherchannel out of 48 from 3750x stack. If you have 100 such 3750x stack you can create 100 vpc on nexus7000
