Adding Static Members to VLANs - CLI

This example adds Port 3 to VLAN 1 as a tagged port, and removes Port3 from VLAN 2.

Configuring VLAN Behavior for Interfaces

You can configure VLAN behavior for specific interfaces, including the default VLAN identifier (PVID),

accepted frame types, ingress filtering, GVRP status, and GARP timers.

Command Usage

GVRP – GARP VLAN Registration Protocol defines a way for switches to exchange VLAN

information in order to automatically register VLAN members on interfaces across the network.

GARP – Group Address Registration Protocol is used by GVRP and GMRP to register or

deregister client attributes for client services within a bridged LAN. The default values for the

GARP timers are independent of the media access method or data rate. These values should not be

changed unless you are experiencing difficulties with GMRP or GVRP registration/deregistration.

Command Attributes
• PVI:
VLAN ID assigned to untagged frames received on the interface.
• Default: 1
• If an interface is not a member of VLAN 1 and you assign its PVID to this VLAN, the
interface will automatically be added to VLAN 1 as an untagged member. For all
other VLANs, an interface must first be configured as an untagged member before
you can assign its PVID to that group.
• Acceptable Frame
Type:
Sets the interface to accept all frame types, including tagged or untagged frames, or
only tagged frames.
When set to receive all frame types, any received frames that are untagged are
assigned to the default VLAN.
• Option: All, Tagged
• Default: All
• Ingress Filtering: If ingress filtering is enabled, incoming frames for VLANs which do not include this
ingress port in their member set will be discarded at the ingress port. However, they
do affect VLAN dependent BPDU frames, such as GMRP.(Default: Disabled)
• Ingress filtering only affects tagged frames.
• If ingress filtering is disabled and a port receives frames tagged for VLANs for which
it is not a member, these frames will be flooded to all other ports (except for those
VLANs explicitly forbidden on this port).
• If ingress filtering is enabled and a port receives frames tagged for VLANs for which
it is not a member, these frames will be discarded.
•
Ingress filtering does not affect VLAN independent BPDU frames, such as GVRP
or
STP. However, they do affect VLAN dependent BPDU frames, such as GMRP.
•GVRP Status: Enables/disables GVRP for the interface. GVRP must be globally enabled for the
switch before this setting can take effect. (See the Displaying Bridge Extension
Capabilitiessection on page 27.)
When disabled, any GVRP packets received on this port will be discarded and no
GVRP registrations will be propagated from other ports.
• Default: Disabled
• GARP Join Timer: The interval between transmitting requests/queries to participate in a VLAN group.
• Range: 20-1000 centiseconds
• Default: 20
• Timer settings must follow this rule: 2 x (join timer) < leave timer < leaveAll timer
