Hello Time
The hello time. See “Hello Time and Bridge Protocol Data Units
(BPDU)” on page 148. This parameter affects only the root bridge.
Maximum Age
The maximum amount of time that BPDUs are stored before being
deleted on the root bridge.
Forward Delay
The time interval between generating and sending configuration
messages by the root bridge.
The bottom section of the web page provides information about the
bridge. The following parameters appear in the bottom third of the web
page:
Bridge ID
The Bridge ID is the MAC address of the bridge. The bridge identifier is
used as a tie breaker in the selection of the root bridge when two or
more bridges have the same bridge priority. You cannot change this
setting.
Bridge Priority
The priority number for the bridge, in hexadecimal format. This number
is used to determine the root bridge for RSTP. The bridge with the
lowest priority number is selected as the root bridge. If two or more
bridges have the same priority value, that is, the lowest value of all the
other bridges, then the bridge with the numerically lowest MAC
address becomes the root bridge. When a root bridge goes offline, the
bridge with the lowest priority number automatically takes over as the
root bridge. This parameter can be from 0X0000 to 0XF000, with
0XF000 being the highest priority.
Bridge Hello Time
This is the time interval between generating and sending configuration
messages by the bridge. This parameter is active only when the switch
is the root bridge.
Bridge Maximum Age
The length of time after which stored bridge protocol data units
(BPDUs) are deleted by the bridge.
Bridge Forward Delay
This is the time interval between generating and sending configuration
messages by the bridge.
