Port Fast
Defines the port contribution to the root path cost. When Default Path Cost is
disabled, you can configure it; when Default Path Cost is enabled, you can
not configure it , and the possible field values are:
65535: Indicates Path Cost Default Values is short. This is the default
value.
200000000: Indicates Path Cost Default Value is long.
Defines the priority value of the port. The priority value influences the port
choice when a bridge has two ports connected in a loop. The priority value is
between 0-240. The default is 128.
Specifies whether a Point-to-Point link is established, or if the switch is
permitted to establish a Point-to-Point link. The possible field values are:
No Change: Retains the current port status.
Auto: Enables the switch to establish automatically Point-to-Point link.
This is the default value.
Point to Point: Indicates if a Point-to-Point link is currently established on
the port. Ports set to Full Duplex modes are considered Point-to-Point
port links.
Shared: Enables the switch to establish a shared link.
Indicates if STP is enabled on the port. The possible field values are:
Enabled: Indicates that STP is enabled on the port.
Disabled: Indicates that STP is disabled on the port.
Indicates if Fast Link is enabled on the port. If Fast Link mode is enabled for
a port, the port is automatically placed in the Forwarding state when the port
link is up. Fast Link optimizes the STP protocol convergence. STP
convergence takes 30 seconds and is not dependent on the number of
switches in the network.
