Layer 3 Management 24-Port 10/100 + 2-Port Gigabit Ethernet Switch
•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 received STA configuration messages, but
does not forward packets.
Listening Port will leave blocking state due to a topology
change. It starts transmitting configuration mes-
sages, but does not yet forward packets.
Learning Port has transmitted configuration messages for an
interval set by the Forward Delay parameter with
out receiving contradictory information. Port
address is cleared, and the port begins learning
addresses.
Forwarding The port forwards packets, and continues learning
addresses.
•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 des-
ignated bridging device through which this Switch must communicate with
the root of the Spanning Tree.
•Root Cost - The path cost from the root port on this Switch to the root
device.

•Root Cost - The path cost from the root port on this Switch to the root
device.
•Root Port - The number of the port on this Switch that is closest to the
root. This Switch communicates with the root device through this port. If
there is no root port, then this Switch has been accepted as the root
device of the Spanning Tree network.
•Configuration Changes - The number of times the Spanning Tree has
been reconfigured.
•Topology Up Time - The time since the Spanning Tree was last recon-
figured.
