NXA-ENET8POE Gigabit PoE Ethernet Switch

RSTP

RSTP is a protocol that prevents loops in the network and dynamically reconfigures which physical links in the

NXA-ENET8POE should forward frames.

Settings

This page enables you to setup the configuration of RSTP.

RSTP System Configuration:

System Priority:

This parameter configures the spanning tree priority globally for this switch.

The device with the highest priority becomes the STA 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).

Force Version:

Set and show the RSTP protocol to use.

• Normal - use RSTP

• Compatible - compatible with STP.
