4.5.10 VLAN configuration
You can set up to 254 VLAN groups and show VLAN group in this page. VLAN1
is a default VLAN, which is created by system. It cannot be removed at all. This
feature prevents the switch from malfunctions. You can remove any existed
VLAN except the VLAN1.
You can assign the port to be a tagged port or an untagged port by toggling the
port button. There are three types of button in port selection panel:
“U” type: untagged port that will remove VLAN tags from the transmitted
packets.
“T” type: All packets transmitted from this port will be tagged.
“blank” type: This port is not a member of the VLAN group.
If one untagged port belongs to two or more VLAN groups at the same time, it
will confuse the switch and cause flooding traffics. To prevent it, the switch only
allows one untagged port belongs to one VLAN at the same time.
If you want to assign an untagged port from one VLAN to another, you have to
remove it from the original VLAN, or change it to be tagged in the original VLAN first.
VLAN ID: this field requires user to enter the VLAN ID when a new VLAN is
created
Name: this field requires user to assign a name for the VLAN
DHCP-Snooping: enable/disable DHCP-Snooping function for the VLAN
Click OK to save the configuration. To make the configuration effective, go to the
“Save Configuration” page, then click Save.
