4.2.28 VLANs->VLAN Config->Create/Modify 802.1Q Trunk
IEEE 802.1Q is the standard for encapsulating packets and marking them with VLAN information
before sending them across a link between two switches. Use the Create/Modify 802.1Q Trunk
screen to modify the encapsulation behavior on a port-by-port basis rather than on a VLAN-by-VLAN
basis. It can also be used to control VLAN membership on a port-by-port basis. When a port number
is selected, the information for that port is displayed. Frame Type Acceptance: Admit All or Tagged
Only. If Tagged Only, incoming packets which are not tagged with 802.1Q VLAN information are
dropped. If Admit All, all packets are admitted. GVRP: Enabled or Disabled. If Enabled, the switch
allows and responds to dynamic VLAN invitations which it receives over this port in GVRP format. If
Disabled, these packets are dropped. All current VLANs on the switch are displayed in table format.
The check boxes to the right indicate which VLANs this port is currently a member of.
To configure VLAN membership by port:
1. Select a Port from the Port Number menu.
2. Add or remove VLANs as tagged members.
3. Change the Frame Type Acceptance or GVRP settings if desired.
4. Click Apply to implement the changes and display the configuration.
