Object Description
•
Extended Multicast
Filtering Services
This Managed Switch does not support the filtering of individual multicast
addresses based on GMRP (GARP Multicast Registration Protocol) .
•
Traffic Classes This Managed Switch provides mapping of user priorities to multiple traffic
classes. (Refer to “ Class of Service Configuration ”)
•
VLAN Learning
This Managed Switch uses Independent VLAN Learning (IVL) , where each port
maintains its own filtering database.
•
Configurable PVID
Tagging
This Managed 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 ”.)
•
Local VLAN Capable This Managed Switch does not support multiple local bridges outside of the
scope of 802.1Q defined VLANs.
•
GMRP GARP Multicast Registration Protocol (GMRP) allows network devices to
register endstations with multicast groups. This Managed Switch does not
support GMRP; it uses the Internet Group Management Protocol (IGMP) to
provide automatic multicast filtering.
