•
Status
: Indicates whether STP or RSTP is enabled.
•
Bridge Hello Time
: When the switch is the root device, this is the time between
messages being transmitted. The value is from 1 to 10 seconds, with a default of 2.
•
Bridge Forward Delay
: Indicates the time duration the switch will wait from listening
to learning states and from learning to forwarding states. The value ranges from 4 to
30 seconds, with a default of 15.
•
Bridge Max Age
: This is the maximum time a message with STP information is allowed
by the switch before the switch discards the information and updates the address
table again. The value ranges from 6 to 40 seconds with a default 20.
•
Hold Time
: This is the minimum time period to elapse between the transmissions of
configuration BPDUs through a given LAN Port. At most one configuration BPDU shall
be transmitted in any hold time period. This parameter is a fixed parameter, with
values as specified in RSTP standard (3 seconds).
•
Topology Change
: A counter indicating the number of times topology has changed.
•
Time since TC
: Indicates time that has elapsed since the last topology change. Use
this in conjunction with uptime on the graphical display (screen shown after a
successful login) to find the frequency of the topology changes.
