VLAN Trunking: Cisco vs. Dell

In a recent battle at work I put a Cisco 2960G up against a Dell PowerConnect 5424. The PowerConnects aren’t bad… They’re cheap, gigabit, and Layer-2. Anyway, I quickly found out that unless you use GVRP, the Dell cannot learn what VLANs are out there. You have to specify allowed VLANS specifically on both ends of a trunk.

The Cisco 2960G doesn’t support GVRP, and VTP is proprietary, so I was forced to use this method.

On the Cisco:

switchport mode trunk
switchport trunk allowed vlan add 2,100,101
switchport nonegotiate

On the Dell:

switchport mode trunk
switchport trunk allowed vlan add 2,100,101

I’m not creative enough for this, and you can’t help me.
