Solved: Dual Uplinks

JustinGayheart · ‎08-31-2023

Hi Everyone,

I'd like to start getting dual uplinks to my IDFs as I upgrade them.

I have 2 9372 Cisco switches that form a VPC.

Right now I just one uplink into my MS120, I would like to add the 2nd.

I have them already setup for a VPC between the 2 ports.

When i do this, I just need to aggregate the uplinks?

I have attached a pic of what I would like to do.

Nothing needed here. The LAG will only form if the other side is also ready.

With VPCs, the Nexus pair behaves as one switch in the perspective of aggregate links. On the MS you can just build an aggregate, and you are fine.

Is there any trick to do before I aggregate the 2 ports on the MS?

unplug them both, aggregate, plug back in at the same time?
