LABEL DESCRIPTION
STP Status Click STP Status to display the SAM1316-22’s STP status (see
Section 23.2 on page 170 ).
Active Select this check box to turn on RSTP.
Note: It is recommended that you only use STP when you use the
SAM1316-22 in standalone mode with a network topology
that has loops.
Bridge Priority 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. The allowed range is 0 to 61440.
The lower the numeric value you assign, the higher the priority for
this bridge.
Bridge Priority determines the root bridge, which in turn determines
Hello Time, Max Age and Forwarding Delay.
Hello Time This is the time interval in seconds between BPDU (Bridge Protocol
Data Units) configuration message generations by the root switch.
The allowed range is 1 to 10 seconds.
