VLAN C
ONFIGURATION

CLI – This example adds Port 3 to VLAN 1 as a tagged port.
Configuring VLAN Behavior for Interfaces
You can configure VLAN behavior for specific interfaces, inclu ding
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 datarate.
These values should not be changed unless you are
experiencing difficulties with GVRP registration/deregistration.
Command Attributes
•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. (Default:
Disabled)
- Ingress filtering only affects tagged frames.
- If ingress filtering is disabled, the interface will accept any
VLAN-tagged frame if the tag matches a VLAN known to the
switch (except for those VLANs explicitly forbidden on this
port).
