VLAN Tagging across from firewall to 2 SG-300 52 Switchs

[jcejka]

I need some assistance in setting up VLAN's (802.1Q) accross two switchs, I want the same 2 vlan's on both switchs, how do i configure them to be connected and pass both vlan's traffic.

My setup

Internet - Firewall - Switch1 - Switch2

VLANs from firewall are tagged at 3 and 8.Single port out from the firewall

The first switch is simple enough, port is connect at port 52 and configured from both vlan's then the individual ports are either on one or the other.  The question is how do i connect the second switch so that it can also do both vlans.  Assume I connect switch1 at port 51 to switch 2 port 52.  Do I configure both ports to be on the same VLAN's. or do i setup LAG's. All too confusing.

You have already done the confusing part, sounds like you got the hang of it rather quickly. Now all you need to do is set the individual ports which you will be using to connect the switches. Since you only have 2 VLANs then I will guess that VLAN 1 is one of the two, which leaves you with the only ability of tagging the other VLAN.

So, switch1 interface 51 switchport trunk allow vlan 1 vlan 2 --- tag vlan 2

Then, switch 2 interface 52 switchport trunk allow vlan 1 vlan 2 -- tag vlan 2

Note that we are not tagging VLAN 1 which by default is the native VLAN.

Good Luck!

I am a little familar with Catalyst SSH, but since these are Small Business Switchs Im not getting a command prompt.  The window for SSH looks identical to Telnet.

Its pretty much

Oh!!! no I did not mean the lines to imply cli commands (as they are mostly wrong) just meant to show how the ports should be configured. You can do it easily via the Web UI. If you still get stuck on what to configure take a look in this forum for some assistance. About a week ago or so Dave Hornstein posted a real nice step by step for configuring trunk ports using the SG300s.
