How do you dumb down a small business SF300 to a transparent bridge?

How do you dumb down a small business SF300 to a transparent bridge?

Postby Guest » Fri Jan 07, 2005 9:03 pm

I am using the Cisco SF302 switches as a connection to some wireless devices that will link two buildings together.

 

In this configuration: Cisco 3570 in building 1 >> Cisco SF302 >> building 1 wireless bridge >> building 2 wireless bridge >> Cisco SF302 >> Cisco 3560 in building 2.

 

It seems that by default the SF302s are not acting as transparent bridges and just letting all my 802.1Q traffic through.

 

How do I dumb them down so that all 802.1Q traffic is dealt with by the 3570 and 3560 with the SF302s just acting as part of the bridge letting my 802.1Q pass through unimpeded?

 

Thanks.

By default, VLANs are not automatically added to trunk ports. You have to create them and assign them to the trunk ports.This has been done for security reasons.

Yea, what you want to do can be done.

 

What you need to do is configure two trunk ports for each side, configure all of the VLANs manually or via GVRP, and then the switch will let the tagged frames through.

Thanks Jesse - I sort of worked that out in the end. I added the VLANs manually AND activated GVRP AND put the trunk mode to General - and now it is working but whether I needed all three changes in place I am not so sure.

 

When I activated GVRP I expected VLANs to automatically be created on the SF300 - but that did not happen - so the manual creation of the VLANs was necessary and that worked just fine.
