DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide
568
57-20 spanning-tree link-type
This command is used to configure the link type of the interface. Use the no form of the command to restore the
configuration to the default value.
spanning-tree link-type [point-to-point | shared]
no spanning-tree link-type
Parameters
57-21 spanning-tree tc-guard
This command is used to enable the Topology Change guard at the specific interface. Use no form of this command to
disable TCN filtering.
spanning-tree tc-guard
no spanning-tree tc-guard
Example
This example shows how to prevent a interface to being a root port.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#interface tenGigabitEthernet 1/0/1
DXS-3600-32S(config-if)#spanning-tree guard root
Success
DXS-3600-32S(config-if)#
point-to-point Specifies to set the link type of the interface to point-to-point.
shared Specifies to forcibly set the link type of the interface to shared.
Default
For a full-duplex interface, its link type is set to a point-to-point link. For a half-duplex
interface, its link type is set to shared.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 8
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 the forwarding state rapidly by setting the link type to shared-media. Hence, the
auto-determination of link-type by the STP module is recommended.
This configuration will take effect on all the spanning-tree modes.
Example
This example shows how to configure link type.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#interface tenGigabitEthernet 1/0/1
DXS-3600-32S(config-if)#spanning-tree link-type point-to-point
Success
DXS-3600-32S(config-if)#
Parameters
None.
Default
By default, this option is disabled.
Command Mode
Interface Configuration Mode.
