Type Shows port type as:
100TX : 10BASE-T / 100BASE-TX
100FX : 100BASE-FX
1000SX/LX : 1000BASE-SX/X (multimode/ single mode)
1000T : 1000BASE-T
Status Displays current state of this port within the Spanning Tree:
Disabled No link has been established on this port. Otherwise, the
port has been disabled by the user or has failed
diagnostics.
Blocking Port receives STA configuration messages, but does not
forward packets.
Listening Port will leave blocking state due to a topology change,
start transmitting configuration messages, but does not
yet forward packets.
Learning Port has transmitted configuration messages. For an
interval set by the Forward Delay Parameter without
receiving contradictory information. Port address table is
cleared, and the port begins learning addresses.
Forwarding The port forwards packets, and continues learning
addresses.
The rules defining port status are:
• A port on a network segment with no other STA-compliant bridging
device is always forwarding.
• If two ports of a switch are connected to the same segment and
there is no other STA device attached to this segment, the port
with the smaller ID forwards packets and the other is blocked.
•
A
ll ports are blocked when the switch is booted, then some of them
change state to listening, to learning, and then to forwarding.
Designated
Cost
The cost for a packet to travel from this port to the root in the current
Spanning Tree configuration. The slower the media, the higher the
cost.
Designated
Bridge (ID)
The priority and MAC address of the device through which this port
must communicate to reach the root of the Spanning Tree.
Designated Port
(ID)
The priority and number of the port on the designated bridging device
through which this switch must communicate with the root of the
Spanning Tree.
2.6.4.Displaying VLAN Information
These menus display information on the ports that have been automatically learned via
GVRP, and all the ports that have been configured by dynamic or static means to
forward VLAN traffic.
