• Backup — This port provides a backup path to the designated
port. 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 — This port is not participating in the Spanning Tree.
–
Mode — Displays if RSTP is enabled.
–
Fast Link Operational Status — Displays if Fast Link is enabled or
disabled for the port or LAG. If Fast Link is enabled for an interface,
the interface is automatically placed in the forwarding state. The
possible options are:
• Enable — Fast Link is enabled.
•
Disable — Fast Link is disabled.
•
Auto — Fast Link mode is enabled a few seconds after the
interface becomes active.
–
Point-to-Point Admin Status — Select if a point-to-point links is
established, or permits the device to establish a point-to-point link.
The possible options are:
•
Enable — Enables the device to establish a point-to-point link, or
specifies for the device to automatically 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 the actual switch port link type. It
may differ from the administrative state.
• Disable — Disables point-to-point link.
•
Auto — The device automatically establishes a point-to-point
link.
