Create simple Port base VLAN in Powerconnect 2848 Switch

Question

Hi,

Just bought Powerconnect 2848 Switch.

I wish to create 2 diferent VLANs that share 1 port for the internet router.

first vlan is for the department A, second vlan is for department B

computer on vlan1 will not have access to computers on vlan2 and oposite, but both virtual networks will have access to port 1 that is connected to the internet router

VLAN1: 1, 2-24

VLAN2: 1, 25-48

I had before Netgear switch and it was very simple to implement, but did't manage to create it in this switch.

Please help

Here are the definitions that I pulled from page 126 of the User Guide:

T -- The interface is a member of a VLAN. All packets forwarded by the interface are tagged. The packets contain VLAN information.

U -- The interface is a VLAN member. Packets forwarded by the interface are untagged.

F -- The interface is denied membership to a VLAN.

Blank -- The interface is not a VLAN member. Packets associated with the interface are not forwarded.

If you are wanting port 1 to be a “Trunk” and have both VLANs move across the connection. Then you will want port 1 to have a “T” when you view the page with VLAN 2 displayed in the drop down and also when VLAN 3 is displayed. On the port settings page for port 1 you will have the PVID set as VLAN 1

On the port settings page you will want to enter each port and set the PVID to the desired VLAN 2 or 3. This will tag the traffic coming into the port from a VLAN unaware device. Like you would use a switchport access command in the CLI.

So for ports 2-5 you will have VLAN 2 set as U on the VLAN membership table. Then on the port settings page they will have the PVID set as VLAN 2.

For ports 6-8 you have VLAN 3 set as U on the VLAN membership table. Then on the port settings page they will have the PVID set as VLAN 3.

Here is an example of the VLAN port table.

Ports: 1 2 3 4 5 6 7 8

VLAN 1: U B B B B B B B

VLAN 2: T U U U U B B B

VLAN 3: T B B B B U U U

You will need to put the switch into 'Managed Mode.'  This will allow you to configure advanced features like VLAN segmentation. You can enter the Managed Mode by pressing the Manage Mode button on the front of the chassis.  If you need help with the initial Set up Wizard page 44 of the User Guide walks you thru the process. ftp://ftp.dell.com/Manuals/all-products/esuprt_ser_stor_net/esuprt_powerconnect/powerconnect-2808_user%27s%20guide_en-us.pdf The VLAN Port Settings page contains fields for managing ports that are part of a VLAN. The port default VLAN ID (PVID) is configured on the VLAN Port Settings page. All untagged packets arriving to the device are tagged by the ports PVID. To open the VLAN Port Settings page, click Switch / VLAN / Port Settings in the tree view.  Page 124 of the User Guide starts the discussion about VLANs on the 2800 series switch. You will want to enter this page.  Then for ports 25-48 change the PVID to 2.  If you click on the show all it will give you a table that is a little easier to configure multiple ports.

All you said here is - I already know. and its not answering my question. Please look at my question.

I would suggest creating another VLAN and leaving VLAN 1 as the native VLAN (untagged).

From the page shown below you can use the drop down (green circle) to select VLAN 2. Then move down to the table (red circle). There you can toggle between T, F, U and blank. You will want to set that as "T" for tagged. Apply settings.

Then the process will need to be completed for the second VLAN.

This will allow tagged traffic from the specified VLANs to traverse over the connection on port 1. I would still keep the PVID on the Home/Switch/VLAN/Port Settings page as VLAN 1. This will ensure that any untagged traffic will traverse and be in the native VLAN 1.

are you sure it does what I need?

I didn't understand excacty your answer, shout I do it this way (b= blank):

assuming this:

8 ports, port one is shared

vlan 2 use port 2-5

vlan 3 use port 6-8

Ports: 1 2 3 4 5 6 7 8

VLAN 1: U U U U U U U U

VLAN 2: T T T T T B B B

VLAN 3: T B B B T T T T
