Removing an Untagged Port from a VLAN
By default, all the ports on the switch belong to the default VLAN, VLAN1,
as untagged ports. When you assign a port to another VLAN as an
untagged port, the switch removes the untagged port from the original
VLAN and then assigns it to the new VLAN.
Caution
Modifying the VLAN membership of active ports may cause loss of
connectivity to the switch.
To remove an untagged port from the VLAN and leave the port not
belonging to any VLAN, do the following:
1. Hover the cursor over the Switching tab.
The Switching tab is displayed. See Figure 24 on page 65.
2. From the Switching tab drop-down menu, select VLANs .
The VLANs page is displayed. See Figure 51 on page 134.
3. From the VLANs page, click Edit next to the VLAN that the untagged
port you want to remove belongs to.
The Edit VLAN page is displayed. See Figure 53 on page 137.
4. Click a port number until the port is marked as “H” to check the port
with an “H” mark. An “H” indicates the port is removed from all VLANs
on the switch as an untagged port.
Note
When you remove a “U” mark from a port and leave no mark on the
port, and then click
Apply , the switch removes the port from the
VLAN and assigns it to the default VLAN as an untagged port. When
you check a port with an “H” mark, the switch removes the port from
the VLAN, but does not assign it to any VLAN. Even when a port
does not belong to any VLAN as an untagged port, the port can be a
member of a VLAN as a tagged port.
