Chapter 8 VLAN 8.2 Automatic VLAN Registration GARP and GVRP are the protocols used to automatically register VLAN membership across switches. 8.2.1 GARP GARP (Generic Attribute Registration Protocol) allows network switches to register and deregister attribute values with other GARP participants within a bridged LAN. GARP is a protocol that provides a generic mechanism for protocols that serve a more specific application, for example, GVRP. 8.2.1.1 GARP Timers Switches join VLANs by making a declaration. A declaration is made by issuing a Join message using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All message terminates all registrations. GARP timers set declaration timeout values. 8.2.2 GVRP GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a way for switches to register necessary VLAN members on ports across the network. Enable this function to permit VLAN groups beyond the local Switch. Please refer to the following table for common IEEE 802.1Q VLAN terminology. Table 14 IEEE 802.1Q VLAN Terminology VLAN PARAMETER TERM DESCRIPTION VLAN Type Permanent VLAN This is a static VLAN created manually. Dynamic VLAN This is a VLAN configured by a GVRP registration/ deregistration process. VLAN Administrative Registration Fixed Fixed registration ports are permanent VLAN members. Control Registration Forbidden Ports with registration forbidden are forbidden to join the specified VLAN. Normal Registration Ports dynamically join a VLAN using GVRP. VLAN Tag Control Tagged Ports belonging to the specified VLAN tag all outgoing frames transmitted. Untagged Ports belonging to the specified VLAN don't tag all outgoing frames transmitted. VLAN Port Port VID This is the VLAN ID assigned to untagged frames that this port received. Acceptable Frame Type You may choose to accept both tagged and untagged incoming frames, just tagged incoming frames or just untagged incoming frames on a port. Ingress filtering If set, the Switch discards incoming frames for VLANs that do not have this port as a member 80 ES-3124 Series User's Guide

8.2
Automatic VLAN Registration
GARP and GVRP are the protocols used to automatically register VLAN membership across
switches.
8.2.1
GARP
GARP (Generic Attribute Registration Protocol) allows network switches to register and de-
register attribute values with other GARP participants within a bridged LAN. GARP is a
protocol that provides a generic mechanism for protocols that serve a more specific
application, for example, GVRP
.
8.2.1.1
GARP Timers
Switches join VLANs by making a declaration. A declaration is made by issuing a Join
message using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All
message terminates all registrations. GARP timers set declaration timeout values.
8.2.2
GVRP
GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a way for
switches to register necessary VLAN members on ports across the network. Enable this
function to permit VLAN groups beyond the local Switch.
Please refer to the following table for common IEEE 802.1Q VLAN terminology.
Table 14
IEEE 802.1Q VLAN Terminology
VLAN PARAMETER
TERM
DESCRIPTION
VLAN Type
Permanent VLAN
This is a static VLAN created manually.
Dynamic VLAN
This is a VLAN configured by a GVRP registration/
deregistration process.
VLAN Administrative
Control
Registration Fixed
Fixed registration ports are permanent VLAN members.
Registration
Forbidden
Ports with registration forbidden are forbidden to join the
specified VLAN.
Normal Registration
Ports dynamically join a VLAN using GVRP.
VLAN Tag Control
Tagged
Ports belonging to the specified VLAN tag all outgoing
frames transmitted.
Untagged
Ports belonging to the specified VLAN don't tag all
outgoing frames transmitted.
VLAN Port
Port VID
This is the VLAN ID assigned to untagged frames that
this port received.
Acceptable Frame
Type
You may choose to accept both tagged and untagged
incoming frames, just tagged incoming frames or just
untagged incoming frames on a port.
Ingress filtering
If set, the Switch discards incoming frames for VLANs
that do not have this port as a member
