Now Active:

This field shows which communication protocol is being used—Turbo Ring, RSTP, or neither.

Root/Not Root

This field appears only for RSTP mode. It indicates whether or not this PT-7728 is the Root of the Spanning Tree (the root is determined automatically).

At the bottom of this page, the user can configure the Settings for the selected protocol. For RSTP, you can configure:

Protocol of Redundancy

Setting	Description	Factory Default
Turbo Ring	This selects the Turbo Ring protocol.	None
RSTP (IEEE 802.1W/1D)	This selects the RSTP protocol.	None
Bridge Priority
Setting	Description	Factory Default
Numerical value selected	This specifies the PT-7728's bridge priority. A	32768
by user	lower number means a higher priority, which
	means a greater chance of being established as
	the root of the Spanning Tree topology.
