Hello Time
Time (in seconds) that the root waits between sending configuration messages. This
time is advertised by the root and used by all devices and switches in the active
topology of the spanning-tree network.
Max Message Age
Time at which the configuration message used by the spanning tree algorithm
should be discarded. This time is advertised by the root and used by all devices and
switches in the active topology of the spanning tree network.
Forward Delay
Time the root waits between transitions from listening to learning, and from
learning to forwarding. This time is advertised by the root and used by all devices
and switches in the active topology of the spanning tree network.
Port
Port number.
PId (Port ID)
Port ID that is used to determine the role of the port in the spanning tree. The port
ID is expressed in the form
port priority.port number.
PCst (Port Cost)
Cost associated with each port. Lower numbers are generally assigned to ports
attached to faster media (such as FDX or CrossLink), and higher numbers are
generally assigned to ports attached to slower media (such as 2400-baud modem
links).
PSts (Port Status)
Current status of this port within the spanning tree. Possible values are:
•
DIS (Disabled)
•
BLK (Blocked)
•
LSN (Listening)
•
LRN (Learning)
•
FWD (Forwarding)
•
DWN (Down)
DCst (Designated Cost)
Cost for a packet to travel from this port to the root in the current spanning tree
configuration. Found by adding all path cost to the root when using the designated port.
