Configuring The Current Device As The Root Bridge Of A Specific Spanning Tree; Configuring The Current Device As A Secondary Root Bridge Of A Specific Spanning Tree; Configuring The Device Priority - HP 6125G Configuration Manual

Configuring the current device as the root bridge of a specific
spanning tree
Step
1. Enter system view.
2. Configure the current device
as the root bridge.
Configuring the current device as a secondary root bridge of a
specific spanning tree
Step
1. Enter system view.
2. Configure the current
device as a secondary root
bridge.

Configuring the device priority

CAUTION:
You cannot change the priority of a device after it is configured as the root bridge or as a secondary root
bridge.
Device priority is a factor in spanning tree calculation. The priority of a device determines whether the
device can be elected as the root bridge of a spanning tree. A lower numeric value indicates a higher
priority. You can set the priority of a device to a low value to specify the device as the root bridge of the
spanning tree. During root bridge selection, if all devices in a spanning tree have the same priority, the
one with the lowest MAC address will be selected as the root bridge of the spanning tree. A spanning
tree device can have different priorities in different MSTIs.
To configure the priority of a device in a specified MSTI:
Step
1. Enter system view.
