4.4.8 RSTP
The switch supports IEEE 802.1D-2004 RSTP protocol, the RSTP protocol can backward
compatible to legacy Spanning Tree Protocol (STP) and 802.1w Rapid Spanning Tree
Protocol (RSTP).
 Force version:
STP and RSTP. Select the STP version you want to enabled.
 System Priority
This parameter configures the spanning tree priority globally for this switch. The device
with the highest priority becomes the STP root device. However, if all devices have the
same priority, the device with the lowest MAC address will then become the root device.
Number between 0 - 61440 in increments of 4096. Therefore, there are 16 distinct
values.
 Hello Time
Interval (in seconds) at which the root device transmits a configuration message
(BPDU frame). Number between 1-10 (default is 2).
 Max Age
The maximum time (in seconds) a device can wait without receiving a configuration
message before attempting to reconfigure. That also means the maximum life time for
a BPDU frame. Number between 6-40 (default is 20).
 Forward Delay
The maximum time (in seconds) the root device will wait before changing states (i.e.,
discarding to learning to forwarding). Number between 4–30 (default is 15)
