AdminEdge: Allows you to set whether the Port is connected directly to an Edge Device. This allows Transition to
the Forwarding State Faster for Edge Ports than non-Edge Ports. The value of this flag is based on the AdminEdge and
AutoEdge settings. When set to Edge it is displayed as Edge in Monitor>Spanning Tree>Port Status.
X
Edge: The Port has been set as an Edge Port and will Transition to Forwarding state faster.
X
Non-Edge: The Port is not set as an Edge Port and will follow normal Transition timing. This is the default value.
X
AutoEdge: Allows you to set whether the Switch should attempt Edge Port detection. This allows the AdminEdge
state to be derived from whether BPDU’s are received on the Port or not.
Restricted Role: Allows you to Restrict the Port so it will not to be selected as Root Port for the CIST or any MSTI, even
if it has the best Spanning Tree Priority. The Port will be selected as a Backup after the Root Port has been selected.
Restricted Role can be set by the Network Administrator to prevent bridges external to a core region of the Network
from influencing the Spanning Tree Active Topology. This feature is also known as Root Guard.
w Warning: This setting can cause lack of Spanning Tree connectivity.
Restricted TCN: Allows you to Restrict the Port so it will not Propagate Received Topology Change Notifications and
Topology Changes to other Ports. Restricted TCN can be set by the Network Administrator to prevent bridges external
to a core region of the Network from causing Address flushing within that region. An example of use would be when the
Physical Link State of an attached LAN(s) Transitions frequently.
n NOTE: This setting can cause temporary loss of connectivity after changes to a Spanning Tree Active Topology as a result of
incorrect learned station location information.
BPDU Guard: Allows you to set the Port to Disable itself upon receiving valid BPDU’s. Port Edge status will not affect
this setting. A Port that has entered error-Disabled State due to this setting is subject to the bridge Port Error Recovery
setting as well.
Point to Point: Allows you to set whether the Port connects to a Point-to-Point LAN rather than to a Shared Medium.
X
Auto: Point-to-Point status is Automatically detected. This is the default setting.
X
Forced True: Allows you to Force the Switch into the Point-to-Point configuration.
X
Forced False: Allows you to Force the Switch to Disable the Point-to-Point configuration.
n NOTE: Transition to the Forwarding State is faster for Point-to-Point LANs than for Shared Media.

X Reset: Click to cancel any unsaved changes and revert to previously-saved values. Not available once changes are saved.
