567
57-18 spanning-tree autoedge
This command is used to enable auto-edge on the interface. Use the disabled option of this command to disable auto-
edge on the interface.
spanning-tree autoedge [disabled]
Parameters
57-19 spanning-tree guard root
This command is used to the guard mode. To return to the default settings, use the no form of this command.
spanning-tree guard root
no spanning-tree guard root
disabled Specifies to disable the auto-edge on the interface.
Default
By default, this option is enabled.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 8
Usage Guideline
In auto mode, the bridge will delay for a period to become edge port if no bridge
BPDU is received
Example
This example shows how to configure auto-edge.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#interface tenGigabitEthernet 1/0/1
DXS-3600-32S(config-if)#spanning-tree autoedge
Success
DXS-3600-32S(config-if)#
Parameters
None.
Default
By default, this option is disabled.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 8
Usage Guideline
BPDU guard prevents a port from being a root port BPDUs. Typically, this feature is
used in a service-provider environment where the network administrator wants to
prevent a low speed port being a root for the local bridge networks. This
configuration will take effect on all the spanning-tree versions.
A Boolean value set by management. If TRUE causes the Port not to be selected as
Root Port for the CIST or any MSTI, even it has the best spanning tree priority
vector. Such a Port will be selected as an Alternate Port after the Root Port has been
selected. This parameter should be FALSE by default. If set, it can cause lack of
spanning tree connectivity. It is set by a network administrator to prevent bridges
external to a core region of the network influencing the spanning tree active topology,
possibly because those bridges are not under the full control of the administrator.
