Connecting a Cat 2950 to a Cat 6509 using a cross over cable. This comes up as trunk but I dont want it to.
When it was first connected, it led to some spanning tree errors as the port vlan at both ends were different. On the C2950, I had vlan 1 and on the C6509, I had Vlan 211. I change the port vlan to 1 on the C6509 and then this was ok but now it is trunking.
I dont want to trunk on these port. What I want it to create a connection as a normal access port in say vlan 211.
How do I do this?
And then after doing the above, will routers connected to the switch be able to talk to each other via vlan 211?
I am running CatOS on the 6509 and IOS on the 2950.
The C2950 is on a remote site. The remote site have said that they do not have any VTP configured as the C2950 is being used as just a hub, so thereby the will not be able to configure vlan 100 for example on the C2950.
This leaves me with why the link came up as a trunk when the links were connected even though on the C6509, it was never configured as a trunk. I feel as if their side forced the C6509 into trunking.
So if they cannot create any extra vlan on their C2950, how else can I configure this connection as an access port?
The 2950 has a default of dynamic desirable on its ports so unless trunking is specifically shutoff on the 6500 it will create a trunk . If the 6500 trunk port is "auto" (default) or desirable the trunk link will come up , just turn the trunk off on the 6500 and the link will not trunk . You can shut it off on the 2950 also by making it an access port also.
