Command Attributes
•Extended Multicast Filtering Services – This switch does not
support the filtering of individual multicast addresses based on
GMRP (GARP Multicast Registration Protocol).
•Traffic Classes – This switch provides mapping of user
priorities to multiple traffic classes. (Refer to “Class of Service
Configuration” on page 2-77.)
•Static Entry Individual Port – This switch allows static
filtering for unicast and multicast addresses. (Refer to “Setting
Static Addresses” on page 2-39.)
•VLAN Learning – This switch uses Shared VLAN Learning
(SVL), where each port shares a common filtering database.
•Configurable PVID Tagging – This switch allows you to
override the default Port VLAN ID (PVID used in frame tags)
and egress status (VLAN-Tagged or Untagged) on each port.
(Refer to “VLAN Configuration” on page 2-52.)
•Local VLAN Capable – This switch does not support multiple
local bridges; i.e., multiple Spanning Trees.
•GMRP – GARP Multicast Registration Protocol (GMRP) allows
network devices to register endstations with multicast groups.
This switch does not support GMRP; it uses the Internet Group
Management Protocol (IGMP) to provide automatic multicast
filtering.
•GVRP – GARP VLAN Registration Protocol (GVRP) defines a
way for switches to exchange VLAN information in order to
register necessary VLAN members on ports across the network.
This function should be enabled to permit VLANs groups which
extend beyond the local switch. (Defau lt: Enabled)
