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 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
GVRP registration/deregistration.
Command Attributes
• PVID –
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. (Options: All, Tagged; Default: All)
• Ingress Filtering – Determines how to process frames tagged for
VLANs for which the ingress port is not a member. (Default:
Disabled)
- Ingress filtering only affects tagged frames.
