–
Auto
— Fast Link mode is enabled a few seconds after the interface becomes active.
•
Port Status
— Indicates the RSTP status on the specific port. The possible field values are:
–
Disabled
— Indicates that STP is currently disabled on the port. The port forwards traffic
while learning MAC addresses.
–
Blocking
— Indicates that the port is currently blocked and cannot forward traffic or
learn MAC addresses.
–
Listening
— Indicates that the port is in Listening mode. The port cannot forward traffic
nor can it learn MAC addresses.
–
Learning
— Indicates that the port is in Learning mode. The port cannot forward traffic,
however it can learn new MAC addresses.
–
Forwarding
— Indicates that the port is in Forwarding mode. The port can forward
traffic and learn new MAC addresses.
•
Point-to-Point Admin Status
— Indicates if a point-to-point links is established, or permits
the device to establish a point-to-point link. The possible field values 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.
•
Point-to-Point Operational Status
— Indicates the Point-to-Point operating state.
•
Activate Protocol Migration Test
— Enables a Protocol Migration Test.The test identifies the
STP mode of the interface connected to the selected interface. The possible field values are
:
–
Checked
— Protocol Migration is enabled.
–
Unchecked
— Protocol Migration is disabled.
