Hi there,
I have little experience with Cisco equipment. As of right now I am trying to connect (trunk I believe) two switches together. The main switch is a 3560 and the other is a catalyst 2950. Someone setup a VLAN on port 48 of the 3560. I want to connect a switch to that port so I can have multiple devices plugged in. First off, is this even possible? Secondly, if it is,how do I go about successfully connecting the two switches?
This is what I have done so far.
On switch 3560 (main switch) the VLAN is 30. (This was created by someone else)
I created VLAN 30 on the 2950 with the range of all ports (1-24) in that VLAN.
Then I set fa0/1 to trunk mode. When the line came back up I got this error.
21:34:39: %SPANTREE-2-RECV_PVID_ERR: Received BPDU with inconsistent peer vlan i d 30 on FastEthernet0/1 VLAN1.
21:34:39: %SPANTREE-2-BLOCK_PVID_PEER: Blocking FastEthernet0/1 on VLAN0030. Inc onsistent peer vlan.
21:34:39: %SPANTREE-2-BLOCK_PVID_LOCAL: Blocking FastEthernet0/1 on VLAN0001. In consistent local vlan.

Again, I have no clue what this is and I would really appreciate some help.
Thanks for looking!
