vlan problems on an SF 300-24P

Unanswered Question

I have a stack of SGE2010P switches with 3 vlans (1, 10 and 255) on it. Connected to it via a trunk port, I have a SF300-24P.

On the trunk ports, I have vlan 1 untagged, vlans 10 and 255 tagged (on both sides, obviously).

On the SGE2010 stack, I can set a ports primary vlan id to vlan 10, and workstations work correctly.

On the SF300, if I set a port to type general, and the ports default vlan to 10  (on the port to vlan page), I cannot get any communication to work.

This is my first time with a non-CLI switch, and am having real problems figuring out how to troubleshoot this problem.

Any pointers would be appreciated.

Hi mike

With the SF300 switch, why not leave the switch port in trunk  mode .

step 1.  verify and if needed upgrade to firmware version as of yesterday,.  but will give you CLI

step 2. put the ports back into trunk mode, the default setting.

Step 3, you have already created the vlan, but i went through the process below..


Step 4.  The ports are all in the default TRUNK  mode allowing one untagged vlan and multiple tagged vlans per port.


Step 5.  I selected VLAN 10  from the drop down and then clicked Go.


step 6. Below I selected ports 5 to 7 as untagged in vlan 10  and my trunk port 28 tagged in vlan 10 then clicked apply.

(port 28 will now transmit untagged ethernet frames belonging to the default vlan and also tagged frames for vlan 10.)


In the following screen capture,  I verified that ports 5 to 7  were now excluded from the default vlan.


That's it. hopefully pretty easy to duplicate.

Below is the CLI created via the GUI, but to access the CLI interface  via the  telnet,  you must  first enable telnet service  as seen by the following screen capture.
