Configuring Bridge MIB Extensions
The Bridge MIB includes extensions for managed devices that support 
Traffic Classes, Multicast Filtering and Virtual LANs. To configure these 
extensions, use the Extended Bridge Configuration screen as shown 
below:
Bridge Capability
Figure 3-18.  Bridge Capability
FastForwarding
ENABLED
This parameter is used to enable/disabled the 
Fast Spanning Tree mode for the port. In this 
mode, ports skip the Blocked, Listening and 
Learning states and proceed straight to 
Forwarding.
FastForwarding enables end-node workstations 
and servers to overcome time-out problems when 
the Spanning Tree Algorithm is implemented in a 
network. Therefore, FastForwarding should only 
be enabled for ports that are connected to an end-
node device.
Parameter
Description
Extended Multicast 
Filtering Services
Indicates that the switch does not support the filtering of 
individual multicast addresses based on GMRP (GARP 
Multicast Registration Protocol). Note that this function is not 
implemented in the current firmware release. 
Traffic Classes
Indicates that the switch provides mapping of user priorities to 
multiple traffic classes. (Refer to the Priority menu on page 28.)
Static Entry 
Individual Port
Indicates that the switch allows the static filtering of unicast and 
multicast addresses. (Refer to the Address Table Configuration 
on page 19.)
Configurable 
PVID Tagging
Indicates that the switch allows you to override the default PVID 
setting (Port VLAN ID used in frame tags) and its egress status 
(VLAN-Tagged or Untagged) on each port. (Refer to VLAN Port 
Configuration on page 36.)
Local VLAN 
Capable
This switch does not support multiple local bridges (that is, 
multiple Spanning Trees).
