Modifying a Port-Based or Tagged VLAN
To modify a VLAN, perform the following procedure:
1. From the Home page, select Configuration.
2. From the Configuration menu, select Layer 2.
3. From the Layer 2 window, select the VLAN tab.
The VLAN menu in Figure 89 on page 279 is displayed.
4. Click the circle next to the name of the VLAN you want to modify.
5. Click Modify.
The configuration menu for the VLAN is displayed.
6. Modify the VLAN parameters by referring to Step 5 to Step 8 in the
previous procedure, Creating A New Port-Based or Tagged VLAN
on page 279.
When modifying a VLAN, observe the following guidelines:
❑ You cannot change the VID of a VLAN.
❑ You cannot change the name of the Default_VLAN.
❑ When changing a VLAN’s name or VID, be sure that the new name
or VID is unique on the switch.
7. After making the desired changes, click Apply.
Note
Untagged ports that are added to a VLAN are automatically
removed from their current VLAN assignment. Untagged ports that
are removed from a VLAN are returned to the Default_VLAN.
Removing an untagged port from the Default_VLAN without
assigning it to another VLAN will leave the port as an untagged
member of no VLAN.
The modified VLAN is now ready for network operations.
