4. Highlight APPLY and press Enter.
5. To enter the change into non-volatile RAM, highlight Save Changes from the Main Menu and
press Enter.
To configure the member ports of an 802.1Q VLAN
1. From the Main Menu, select VLAN Configurations | IEEE 802.1Q Port Settings and press
Enter.
2. Highlight the Configure Port field and enter the range of port numbers you want to configure.
To configure a single port, enter that port number in both the to and from field.
3. Configure these fields.
4. Highlight APPLY and press Enter.
VLAN Type
Specifies the type of VLAN. Use the spacebar to toggle the type to 1Q
VLAN.
VID Specifies an identifier for the VLAN. Enter a number from 2—4094.
Membership
Specifies the status of the port. You can enter the status indicators of
individual ports directly from the keyboard or you can use the spacebar to
toggle between U, T, F, and - .
• U (Untagged)—Designates the port as an untagged member of the
VLAN. When an untagged packet is transmitted by the port, the packet
header remains unchanged. When a tagged packet exits the port, the
tag is stripped and the packet is changed to an untagged packet. If the
port is attached to a device that is not IEEE 802.1Q VLAN compliant
(VLAN-tag unaware), then the port should be set to U - Untagged.
• T (Tagged)—Designates the port as a tagged member of the VLAN.
When an untagged packet is transmitted by the port, the packet header
is changed to include the 32-bit tag associated with the PVID (Port
VLAN Identifier). When a tagged packet with a different VID exits the
port, the packet header is unchanged. If the port is attached to a device
that is IEEE 802.1Q VLAN compliant, (VLAN-tag aware), then the port
can be set to T - Tagged.
• F (Forbidden)—Designates the port as not being a member of the
VLAN and prevents packets tagged with the VLAN’s VID from entering
the port.
• - (non-member)—Designates the port as not being a member of the
VLAN.
Field Description
Field Description
Ingress Checking
Enables or disables ingress filter checking. Ingress Filtering allows the port
to compare the VID tag of an incoming packet with the PVID number
assigned to the port. If the two are different, the port filters (drops) the
packet. Use the spacebar to toggle between On and Off.
GVRP
Enables or disables GVRP (Group VLAN Registration Protocol). This allows
the switch to share VLAN information with other switches so that a VLAN
can span multiple switches.
