VLANs Spanning Multiple 802.1Q Tagged Switches - 450's

[jimbo01]

I am having a problem adding a standalone 450 switch to a stack of 450's.

The Stack is configured with various port-based VLANS. Two of which are VLAN's 80 and 90.

On the new 450, VLAN's 80 and 90 are going to be configured. So VLAN 80 on the standalone switch needs to have access to VLAN 80 on the stack and same for VLAN 90.

I am having difficulty configuring the new switch to connect to the stack.

Can anyone give me any pointers, and tell me what has to be configured for this to work.

Thanks.

I am assuming you are not just making the stack larger, this is a switch that attaches via ethernet. SInce we will change the connectivity of the new switch, I am assuming we are using the console cable, not telnet or JDM.

In the new switch, pick the port to connect to the stack (often 24) in Vlan Configuration make port 24 part of VLAN 80 (you may wish to make 80 be the management VLAN, if it's IP number is in VLAN 80) Then in Port configuration Make it have a PVID of 80 and be a trunk in Tagging. Now go back to VLAN configuration and add port 24 to VLAN 90

Now in the stack pick a port (unit 1 port 24 as an example) to be the trunk to the standalone switch. In VLAN configuraton make it part of VLAN 80, then in VLAN Port configuration give it a PVID of 80 and Tag it as a Trunk. Now go back to VLAN configuration and add the Port to VLAN 90

I tried to remain child-like, all I acheived was childish.

Thanks for the feedback. How do i add port 24 to VLAN 90 ?

Once It is tagged, it can be part of more than one VLAN, in the text mode you can go to VLAN Configuration, choose VLAN 90 and use that odd tab, space bar, return selection interface

tab repeatedly til you are over the port to change hit space bar to change a port, then return ( or enter) to record the change.

Or if you have it installed with VLAN 80 you can use JDM and its odd click on the right edge of the VLAN interface. Clicking on the right edge of the existing ports brings up a popup to add more ports

There is no need to worry about the PVID once it is tagged
