Multiple VLANs over a Trunk

Hi,

I currently have 2 VLANS setup on 2 Cisco SG500 switches and I am trying to pass both VLANs traffic over my trunk.

My setup includes the following:

Switch 1

VLAN 5 ports 1-32

VLAN 8 ports 33-48

Trunk port 50

Switch 2

VLAN 5 ports 1-32

VLAN 8 ports 33-48

Trunk port 49

My current switch setup includes both switches being setup like the following:

interface gigabitethernet1/1/1 - 32

switchport mode access

switchport access vlan 5

interface gigabitethernet1/1/33 - 48

switchport mode access

switchport access vlan 8

interface gigabitethernet1/1/49 - 50

switchport trunk allowed vlan add 5, 8

I am unable to ping any computers over the trunk.

Any idea what i'm missing in my setup?

Thanks!

Re: Multiple VLANs over a Trunk

Hi Mike, you're missing the ability to communicate across the VLANS. You need something to route the VLANS, in your case, based off this output your router should be doing this.

If you want the switches to route the VLANS you may reference parts of this post to see how to make that happen-

Re: Multiple VLANs over a Trunk

Hi Tom,

I don't believe i'm acutally trying to route anything.  The VLAN traffic is not destinted for any other VLAN.  So switch 1, port 1 should be able to ping switch 2, port 1.

My main problem is setting up the VLANs and the connection between the two switches.  Perhaps I shouldn't be using a trunk for this?

Hi all,

Turns out I had an extra uplink running between my two switches (thanks co-workers) and this was causing STP to block the uplink I was trying to run my multiple VLANs across.  Rookie mistake, thanks for the input.
