Bridge Max Age: This value may be set to ensure that old
information does not endlessly circulate through redundant paths in
the network, preventing the effective propagation of the new
information. Set by the Root Bridge, this value will aid in determining
that the Switch has spanning tree configuration values consistent with
other devices on the bridged LAN. If the value ages out and a BPDU
has still not been received from the Root Bridge, the Switch will start
sending its own BPDU to all other switches for permission to become
the Root Bridge. If it turns out that the Switch has the lowest Bridge
Identifier, it will become the Root Bridge. A time interval may be
chosen between 6 and 40 seconds. The default value is 20.
Bridge Hello Time: The user may set the time interval between
transmissions of configuration messages by the root device, thus
stating that the Switch is still functioning. The default is 2 seconds.
Bridge Forward Delay: This sets the maximum amount of time that
the root device will wait before changing states. The default is 15
seconds.
Root Bridge: Displays the MAC address of the Root Bridge.
Root port: Displays the root port.
Root Path Cost: Shows the root path cost.
Path Cost: This defines a metric that indicates the relative cost of
forwarding packets to specified port list. The lower the number, the
greater the probability the port will be chosen to forward packets. The
default value is 19.
Path Priority: Select a value between 0 and 255 to specify the
priority for a specified port for forwarding packets: the lower the
value, the higher the priority. The default is 128.
