Managing the Module 2-83
The Device View
IVL — Independent VLAN Learning
SVL — Shared VLAN Learning
IVL/SVL — Both Independent and Shared VLAN Learning
Configurable PVID Tagging
Devices that implement this functionality have the ability to override the default PVID
setting and the egress state (Tagged or Untagged) on each port.
Local VLAN Capable
Devices that implement this functionality can support multiple local bridges, outside of
the scope of 802.1Q defined VLANs.
Traffic Classes
The Current and Desired fields display whether Traffic Classes (queues) are currently
enabled or disabled on the device and allow you to change the setting. When Traffic
Classes are enabled, the device can map user priority to specific traffic queues.
GMRP
The Current and Desired fields display whether GMRP (GARP Multicast Registration
Protocol) is currently enabled or disabled on the device and allow you to change the
setting. GMRP is a protocol used to register multicast addresses on ports to control
flooding of multicast frames.
GVRP
The Current and Desired fields display whether GVRP (GARP VLAN Registration
Protocol) is currently enabled or disabled on the device and allow you to change the
setting. GVRP is a protocol used to dynamically add VLANs to port egress lists across a
domain.
The Bridge Port Capability table lists the ports on the device and whether they
implement certain IEEE 802.1D and 802.1Q functionality:
Port
Displays the number that identifies the port.
VLAN Tagging
Ports that implement this functionality support 802.1Q VLAN tagging of frames and
GVRP (GARP VLAN Registration Protocol).
Configure Frame Types
Ports that implement this functionality allow you to configure the port's Acceptable Frame
Types. This setting specifies whether a port will accept both tagged and untagged frames,
or only tagged frames.
Ingress Filtering
Ports that implement this functionality support the discarding of any frame received on a
port whose VLAN classification is not on that port's egress list.
