Creating a port-based VLAN
The 1424T supports port-based VLANs. A port-based VLAN is a VLAN in which the ports are explicitly configured to be in the VLAN. When creating a port-based VLAN on a switch, you assign a VLAN identification number (VLAN ID) and specify which ports belong to the VLAN. The VLAN ID is used to coordinate VLANs across multiple switches.
To create a port-based VLAN:
- From the Device Manager menu bar, choose VLAN > VLANs.
| The VLANs dialog box opens with the Basic tab displayed. |
The table that follows describes the fields in the Basic tab.
|
Id
|
The VLAN ID used for the VLAN.
|
Name
|
The name of the VLAN.
|
PortMembers
|
The ports belonging to this VLAN. Note that a port belonging to the PortMembers field cannot belong to ForbiddenPorts in the same VLAN.
|
ForbiddenPorts
|
The ports that are not allowed to become members of this VLAN.
|
UntaggedPorts
|
The set of ports belonging to this VLAN which transmit the frame as untagged. Untagged ports are part of the PortMembers in that VLAN.
If a port is an UntaggedPort in one VLAN, it cannot act as an UntaggedPort for another VLAN. In such cases, you need to remove the port from the first VLAN before assigning it to the second VLAN as an UntaggedPort.
|
- Click Insert.
| The VLAN, Insert Basic dialog box opens. |
- In the ID field, type the VLAN ID.
| Assign a value from 1 to 4094, as long as it is not already in use. (The default VLAN has a VLAN ID of 1.) |
- In the Name field, type the VLAN name (optional).
| If no name is entered, a default is created. |
- Specify the port membership by clicking the PortMembers ellipsis button.
| The dot1QVlanStaticEgressPorts dialog box opens. |
| For port-based VLANs, you specify whether ports are always members by selecting the member ports. These ports display depressed, while the nonselected ports display not depressed. Port numbers that display in gray indicate ports that cannot be selected to belong to the VLAN. (For example, you cannot select ports that do not have the same spanning tree group ID as that of the new VLAN.) |
- Specify the forbidden ports by clicking the ForbiddenPorts ellipsis button.
| The dot1QVlanForbiddenEgressPorts dialog box opens. |
- Specify the untagged ports by clicking the UntaggedPorts ellipsis button.
| The dot1QVlanStaticUntaggedPorts dialog box opens. |
| For example, for steps 5 thru 7: |
- Assign ports 1-4 to PortMembers.
- Assign ports 5-6 to ForbiddenPorts.
- Assign port 1 to UntaggedPorts since port 1 belongs to the PortMember set.
- If port 1 is an UntaggedPort in another VLAN, remove it from that VLAN.
- Then, add it to this VLAN's UntaggedPorts set.
- On the VLAN, Insert Basic dialog box, click Insert.
