The following table describes the labels for the RSTP Port Setting screen.
Label Description
Port The switch port number of the logical RSTP port
Enabled Controls whether RSTP is enabled on this switch port.
Path Cost
The Auto setting will set the path cost as appropriate by the physical link
speed, using the 802.1D 2004 recommended values.
By using the
Specific setting, a user-defined value can be entered. The path
cost is used when establishing the active topology of the network. Lower path
cost ports are chosen as forwarding ports in favor of higher path cost ports.
Valid values are in the range 1 to 200000000.
Priority
Enter which port should be blocked by setting the priority on the LAN. Enter
a number between 0 and 240. The value of priority must be a multiple of 16.
Admin Edge
Admin Edge is the port which is directly connected to end stations. It cannot
create a bridging loop on the network. To configure the port as an edge port,
set the port to
Edge . The other option is Non-Edge .
Auto Edge
Controls whether the bridge enables automatic edge detection on the Bridge
port. This allows operEdge to be derived from whether BPDU's are received
on the port or not.
Admin P2P
Controls whether the port connects to a point-to-point LAN rather than to a
shared medium. This can be automatically determined
— when Auto option
is selected, or Forced True or Forced False . Transition to the forwarding
state is faster for point-to-point LANs than for shared media.
Save Click Save to apply the configurations.
Reset
Click Reset to undo any changes made locally and revert to previously
saved values.
Bridge Status
This page provides detailed information on a single RSTP Bridge instance.
This is the screen with RSTP disabled.

The following table describes the labels for the RSTP Bridge Status screen.
Label Description
Auto-refresh Check this box to enable an automatic refresh of the page at regular intervals.
Refresh Click Refresh to refresh the page immediately.
Root Bridge ID The Bridge ID of this Bridge instance.
Root Port The switch port currently assigned to the Root Port role.
Path Cost
This is the Root Path Cost. For the Root Bridge , this is zero. For all other Bridges,
it is the sum of the Port Path Costs on the least cost path to the Root Bridge.
Max Age The maximum age of information defined in this device.
Hello Time The time that the Control Switch sends out the BPDU (Bridge Protocol Data Unit).
Forward Delay
The delay used by STP Bridges to transit Root and Designated Ports to Forwarding
(used in STP compatible mode).
