RSTP Port Settings
Port Displays the port number.
Participate Indicates the port is not participating in the
Spanning Tree.
Cost Displays the cost path between devices.
Priority Displays the priority value of the port.
Port Fast Indicates if the port has been designated as a
port fast port. If the port has been designated port fast,
the port immediately transitions to the forwarding state.
Force Point-to-Point Link Mode
Point Link Status.
Status Displays current state of this port within the
Spanning Tree:
Discarding
• Port receives STA configuration messages,
but does not forward packets.
Learning Port has transmitted configuration messages
•
for an interval set by the Forward Delay parameter
without receiving contradictory information. Port
address table is cleared, and the port begins learning
addresses.
Forwarding
• Port forwards packets, and continues
learning addresses.
Role Indicates the port role assigned by the STP algorithm
in order to provide to STP paths. The possible field values
are:
Root
• Provides the lowest cost path to forward packets
to root switch.
Designated Indicates the port via which the
•
designated switch is attached to the LAN.
• Alternate Provides an alternate path to the root
switch from the root interface.
Backup Provides a backup path to the designated
•
port path forward the Spanning Tree leaves. Backup
ports occur only when two ports are connected in a
loop by a point-to-point link. Backup ports also occur
when a LAN has two or more connections connected
to a shared segment.
Disabled
• Indicates the port is not participating in the
Spanning Tree.

Port Select the port range to configure.
Cost By default this value is set to Auto. When auto is
disabled, a value between 1 and 200,000,000 can be
entered. Cost is the contribution value of this port to
the patch cost of paths to the spanning tree root which
include this port.
Priority This is the value of the priority field contained in
the first octet of the port ID. The default value is 0. The
value can range from 0-240.
Port Fast To designate as port fast, click Yes from the
drop-down menu. If a port has been designated port fast,
the port immediately transitions to the forwarding state.
Force Point-to-Point Link Mode
to-point links are established, or permits the device to
establish a point-to-point link. The possible field values
are:
Yes Enables the device to establish a point-to-point
•
link. To establish communications over a point-to-
point link, the originating PPP first sends Link Control
Protocol (LCP) packets to configure and test the data
link. After a link is established and optional facilities
are negotiated as needed by the LCP, the originating
PPP sends Network Control Protocols (NCP) packets
to select and configure one or more network layer
protocols. When each of the chosen network layer
protocols has been configured, packets from each
network layer protocol can be sent over the link. The
link remains configured for communications until
explicit LCP or NCP packets close the link, or until some
external event occurs. This is actual switch port link
type. It may differ from the administrative state.
No Disables point-to-point link.
•
Auto Point-to-point links are automatically established

by the device.
