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
