Active-Active link

infarakesh — Mon, 04 Feb 2013 18:37:24 GMT

Hi,

we would like to achieve active-active link using a single 10G link each from the 2 flex-10 modules to get 20GB (which goes to 2 different Nexus 5K switches)

Is this possible and if yes, how can we do it?

I am hearing about some DIP switch on the VC moduels too. where can we set that?

Thanks!

It's not possible, your two uplinks need to come from the same Flex-10 interconnect. It seems I heard that that may change with a firmware update, but I was just looking at some info on 4.0 and didn't see anything on it.

I believe with vPC setup you can go from one interconnect to two 5k's.

It is possible. You just need to set up an Active-Active configuration on the Virtual Connect, as described in the cookbook. What you can't do is have the two uplinks joined in a single virtual portchannel (vPC) on the Nexus switches, as the Virtual Connect systems will not allow you to bind the two uplinks into a single aggregated link, since they are on two different interconnect modules.
