1) Eliminate broadcast storms which severely degrade performance in a flat network.
2) Simplify network management for node changes/moves by remotely configuring
VLAN membership for any port, rather than having to manually change the network
connection.
3) Provide data security by restricting all traffic to the originating VLAN, except
where a connection has been configured between separate VLANs using a router
or Layer 3 switch.
VLAN Support
VLANs are collections of switching ports that comprise a single broadcast domain. Packets are
classified as belonging to a VLAN based on either the VLAN tag or based on a combination of
the ingress port and packet contents. Packets sharing common attributes can be grouped in
the same VLAN.
Port Based Virtual LANs (VLANs)
Port-based VLANs classify incoming packets to VLANs based on their ingress port.
For more information, see "Defining VLAN Ports Settings".
IEEE802.1V Protocol Based Virtual LANs (VLANs)
VLAN classification rules are defined on data-link layer (Layer 2) protocol identification.
Protocol based VLANs isolate Layer 2 traffic for differing Layer 3 protocols.
Full 802.1Q VLAN Tagging Compliance
IEEE 802.1Q defines an architecture for virtual bridged LANs, the services provided in VLANs
and the protocols and algorithms involved in the provision of these services. An important
requirement included in this standard is the ability to mark frames with a desired Class of
Service (CoS) tag value (0-7).
GVRP Support
GARP VLAN Registration Protocol (GVRP) provides IEEE 802.1Q-compliant VLAN pruning
and dynamic VLAN creation on 802.1Q trunk ports. When GVRP is enabled, the Ethernet
Switch Module registers and propagates VLAN membership on all ports that are part of the
active underlying
"Spanning Tree Protocol Features"
topology.
GMRP Protocol
GARP Multicast Registration Protocol (GMRP) is a Generic Attribute Registration Protocol
(GARP) application that provides a constrained multicast flooding facility similar to IGMP
snooping. GMRP and GARP are industry-standard protocols defined by the IEEE
802.1p.GMRP provides a mechanism that allows bridges and end stations to dynamically
register group membership information with the MAC bridges attached to the same LAN
segment and for that information to be disseminated across all bridges in the Bridged LAN that
supports extended filtering services. The operation of GMRP relies upon the services provided
by the GARP. GMRP software components run on both the switch and on the host. On the host,
GMRP is typically used with IGMP: the host GMRP software spawns Layer 2 GMRP versions
of the host's Layer 3 IGMP control packets. The switch receives both the Layer 2 GMRP and
the Layer 3 IGMP traffic from the host. The switch uses the received GMRP traffic to constrain
