D-Link DXS-1210-12TC Reference Manual page 317

Usage Guideline
A full-duplex port is considered to have a point-to-point connection; on the opposite, a half-duplex port
is considered to have a shared connection .The port can't transit into forwarding state rapidly by
setting link type to shared-media. Hence, auto-determined of link-type by the STP module is
recommended.
This configuration will take effect for all the spanning-tree modes.
Example
This example shows how to configure the link type to point-to-point for port eth1/0/7.
Switch# configure terminal
Switch(config)#interface eth 1/0/7
Switch(config-if)# spanning-tree link-type point-to-point
Switch(config-if)#
39-11
This command is used to configure the STP mode. Use the no form of this command to revert to the
default setting.
spanning-tree mode {mstp | rstp |stp}
no spanning-tree mode
Parameters
mstp
rstp
stp
Default
By default, this mode isrstp.
Command Mode
Global Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
If the mode is configured as STP or RSTP, all currently running MSTP instances will be cancelled
automatically. If the newly configured mode is changed from the previous one, the spanning-tree state
machine will restart again, therefore all of the stable spanning-tree port states will transit into
discarding states.
Example
This example shows how to configure the running version of the STP module to RSTP.
Switch# configure terminal
Switch(config)#spanning-tree mode rstp
Switch(config)#
