2.2.7.11 GVRP
The Generic Attribute Registration
Protocol (GARP) VlAN Registration
Protocol (GVRP) is an application
defined in the IEEE 802.1Q
standard that allows for the control
of VlANs. GVRP will run only on
802.1Q trunk ports and is used
primarily to prune traffic from
VlANs that doesn’t need to be
passed between trunking switches.
There are some parameters for
configuring GVRP on the GVRP
Mode screen; the second screen
option is GVRP Timer (shown
below):
GVRP Enable: By default, GVRP
is not enabled for the switch. You must first enable GVRP on the switch before you can
configure the 802.1Q ports for GVRP operation.
Port Mode: Enable/disable GVRP on the individual 802.1Q trunk port. GVRP must be configured
on both sides of the trunk to work correctly.
Registration: By default,
GVRP ports are in
normal registration
mode. These ports
use GVRP “join”
messages from
neighboring switches
to prune the VlANs
running across the
802.1Q trunk link. If
the device on the other
side is not capable of
sending GVRP
messages, or if you do
not want to allow the
switch to prune any of
the VlANs, use the
fixed mode. Fixed-
mode ports will forward for all VLANs that exist in the switch database. Ports in forbidden
mode forward only for VlAN 1.
2.2.7.12 QoS/CoS
Three screens are presented in QoS/CoS (Quality of Service/Class of Service): 802.1p Priority,
QoS Queue Mapping and QoS Bandwidth.
2.2.7.12.1 802.1p Priority
Each port has eight egress queues. These queues can either be configured with the Weighted
Round Robin (WRR) scheduling algorithm, or with one queue as a strict priority queue and the
other queues for WRR. The strict priority queue must be empty before the other queues are
