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!

I ran this command and the laptop connected to directly to port 48 on the MAINSWITCH still does not have internet access. Do I need to put a default ip on the VLAN?

Thank you for taking the time,

Ok, sounds like you have a lot more work to do. Here are a couple questions:

- were you told to use VLAN 30 as a test by someone who appropriately said VLAN 30 was usable. If you were, can you ask if the main switch is L3 or L2 to a router-on-a-stick or other L3 gateway?

- send the output of a "show cdp nei" command from the main switch

- send the output of a "show ip int br | ex unass" from the main switch

samador382 · ‎12-30-2015

Here is a little more info to better understand my environment.

That MAINSWITCH has a few VLANS on it already. The VLAN 30 was setup by a company that hosts some of our servers.

The VLAN 30 is what I want to use as a test environment. All other VLANS on this switch have internet access. When the guy setup the VLAN on that MAINSWITCH, he was supposed to ensure internet access was possible.

Unfortunately for me, this network has been inherited from a person who is no longer with the company, and the people who host some of our servers charge for everything. They charged us just to setup the VLAN in the first place. $100.

I should probably contact them and let them know it is not working. But they might want to charge since changes have been made to it. I will try anyway. However, for the sake of getting this running, I am pretty sure it is a Layer 2 Switch. Below is the show commands you asked for.

Looks like configurations are still missing from the 3560. Can you re-paste that 3560 configurations provided into the 3560 (not 2950 switch).

It appears that the 3560 rejected the "switchport encapsulation dot1q" command from the output you posted. A "show version" command output may help me understand why.

Ok, I see the issue. Sorry, typing commands form memeory. Paste the following into your 3560:

interface FastEthernet0/48

shut

switchport trunk encapsulation dot1q

switchport mode trunk

auto qos voip trust

no shut

end

wr mem

After done, check on that switch to see if that port is trunking and forwarding VLANs 1 and 30 via the "show interface trunk" command.

samador382 · ‎12-29-2015

OK. I pasted the configurations on both switches.
