We have 10 switches in the datacenter but only have 5 connections back to our 6509 core switches running as a VSS pair. We purchased a couple of 4900M to bring 10G to the datacenter and provide dual uplink on every switch back to the core. I will have dual 10G links on each 4900 back to the 6509 and plan on using a 1G link on each 4900 to each switch. Right now the 6509 does all the VLAN routing.
My question is in the best practice configuration of the 4900. Do I configure this as just a layer 2 switch with every port set as a trunking port? Or should I be moving any layer 3 routing to this switch?
I'm thinking of using it just as a layer 2, but want to make sure I'm doing this right before putting in in production.
