Enabling or Disabling Port GVRP
■
Setting the GVRP Registration Type
■
When you configure GVRP, you need to enable it globally and for each port
participating in GVRP. Similarly, the GVRP registration type can take effect only
after you configure port GVRP. In addition, you must configure GVRP on the trunk
port.
Enabling or Disabling Global GVRP
Use the following commands to enable or disable global GVRP.
Perform the following configurations in system view.
Table 13 Enabling/Disabling Global GVRP
Operation
Enable global GVRP
Disable global GVRP
By default, GVRP is disabled on a port.
Enabling or Disabling Port GVRP
Use the following commands to enable or disable GVRP on a port.
Perform the following configurations in Ethernet port view.
Table 14 Enabling/Disabling Port GVRP
Operation
Enable port GVRP
Disable port GVRP
You should enable GVRP globally before you enable it on the port. GVRP can only
be enabled or disabled on a trunk port.
By default, global GVRP is disabled.
Setting the GVRP Registration Type
The GVRP includes normal, fixed, and forbidden registration types (see IEEE
802.1Q).
When an Ethernet port registration type is set to normal, the dynamic and
■
manual creation, registration, and logout of VLAN are allowed on this port.
When one trunk port registration type is set to fixed, the system adds the port
■
to the VLAN if a static VLAN is created on the switch and the trunk port allows
the VLAN passing. GVRP also adds this VLAN item to the local GVRP database,
one link table for GVRP maintenance. However, GVRP cannot learn dynamic
VLAN through this port. The learned dynamic VLAN from other ports of the
local switch will not be able to send statements to the outside through this
port.
