Description
This is the MAC address of the root bridge.
Root refers to the base of the spanning tree (the root bridge). This field
displays the root bridge's priority. This Switch may also be the root
bridge.
This is the maximum time (in seconds) the Switch can wait without
receiving a configuration message before attempting to reconfigure.
This is the time interval (in seconds) at which the root switch transmits
a configuration message. The root bridge determines Hello Time, Max
Age and Forwarding Delay.
This is the time (in seconds) the root switch will wait before changing
states.
This is the MAC address of the current bridge.
Priority is used in determining the root switch, root port and designated
port. The switch with the highest priority (lowest numeric value)
becomes the STP root switch. If all switches have the same priority, the
switch with the lowest MAC address will then become the root switch.
Priority determines the root bridge, which in turn determines the Root
Hello Time, Root Maximum Age and Root Forwarding Delay.
This is the maximum time (in seconds) the Switch can wait without
receiving a BPDU before attempting to reconfigure. All Switch ports
(except for designated ports) should receive BPDUs at regular intervals.
Any port that age out STP information (provided in the last BPDU)
becomes the designated port for the attached LAN. If it is a root port, a
new root port is selected from among the Switch ports attached to the
network.
