Spanning Tree; Stp Bridge Settings - EverFocus ES0812-31 User Manual

4.8 Spanning Tree

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).

4.8.1 STP Bridge Settings

The Table allows you to configure STP Mode and the system time settings.
 STP Mode: Disable, STP and RSTP. Select the STP version you want to enabled.
 Bridge 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
