Nexus 5000 and nexus 2000 trunk connection

Hi,

I have a nexus 5000 with one 2232 and a 2248 connected as fex.

the 5K is doing layer 3. Do i need to enable some trunking to pass vlans across to 2232 and 2248 or will it work if fex is online and all vlans are there in the N5k.

thanks for all response.

Hello Suthomas,

When you connect the 5K, to the 2K's you "switchport mode fex-fabric". Once online, this essentially expands the 5k's port-density, the FEX's are part of the 5k. So you do not manually extend/pass vlans to the FEX's, as long as the vlans are on the 5k, you should be good to go .

As Gabriel also said, look at the 2ks as dumps switches. You don't configure them at all. They are just extended ports that happens to be in a different switch. Think of each fex as a blade for the 5k. The 5k also upgrade the code on 2ks, as long the 2ks are online
