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.
MAX Age
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.
This is the time interval in seconds between BPDU (Bridge
Hello Time
Protocol Data Units) configuration message generations by the
root switch.
This is the maximum time (in seconds) the Switch will wait
before changing states. This delay is required because every
switch must receive information about topology changes
Forward Delay
before it starts to forward frames. In addition, each port needs
time to listen for conflicting information that would make it
return to a blocking state; otherwise, temporary data loops
might result.
Path cost is the cost of transmitting a frame on to a LAN
through that port. It is recommended to assign this value
Path Cost
according to the speed of the bridge. The slower the media,
the higher the cost.
This is the number of the port on the Switch through which this
Root Cost
Switch must communicate with the root of the Spanning Tree.
