RSTP/MSTP. When correctly set for each port, it improves the operation
of protocol. 'True' indicates that the port will be treated as if it is
connected to a point-to-point LAN segment, regardless of any information
to the contrary that the switch receives. 'False' indicates that
the port will be treated as if it is connected to a non-point-to-point
LAN segment, regardless of any information to the contrary that the
switch receives. Set 'False' on any port that is known to be
connected to a hub, bridge, or another switch. 'Auto' value indicates
that the administrator requires the point-to-point status of the MAC
to be determined in accordance with the speciîš¿c MAC procedures.
o priority <0-15> (default: 8 ) - Another value used by spanning tree
to select the forwarding ports. The port with the lowest number has
the highest priority. The range of 0-240 is divided into 16 steps. These
steps are numbered from 0 to 15. The number entered is multiplied to 16
to calculate the priority value to use by the protocol if protocol
version is other than standard STP (802.1D).
o hello-time <<1-10>|global> (default: global) - Time (in seconds)
between message transmissions when the switch is root. Available for
the per-port conîš¿guration in MSTP mode only. The value 'global' means
to use globally conîš¿gured hello-time for the port.
Next Available Options:
â– mode < Norm | Fast | Uplink > -- Set spanning tree operation mode.(p. 645)
â– path-cost -- Set port's path cost value.(p. 646)
â– priority < 0 to 255 > -- Set port priority (the value is in range of 0-240 divided into steps of 16
that are numbered from 0 to 15, default is step 8).(p. 652)
â– spanning-tree instance ist [ETHERNET] PORT-LIST
Usage: spanning-tree ist [ethernet] PORT-LIST ...
Description: Conîš¿gure internal spanning tree (IST) instance ports parameters.
Follow the PORT-LIST with the '?' to get the list of all
possible options.
Next Available Option:
â– path-cost -- Set the internal port pathcost for the IST (default is 'auto').(p. 646)
â– spanning-tree instance < 1 to 16 > [ETHERNET] PORT-LIST
Usage: spanning-tree instance <1-16> [ethernet] PORT-LIST ...
Description: Conîš¿gure MST instance ports parameters. Follow the PORT-LIST
with the '?' to get the list of all possible options.
Next Available Options:
â– path-cost -- Set the port pathcost for the instance (default is 'auto').(p. 646)
â– priority < 0 to 15 > -- Set the port priority for the instance (the value is in range of 0-240 divided
into steps of 16 that are numbered from 0 to 15, default is step 8).(p. 652)
ports
â– spanning-tree clear-debug-counters instance < 0 to 16 > ports [ETHERNET] PORT-LIST
