no spanning-tree externalcost
Parameters
57-17 spanning-tree portfast
This command is used to enable fast forwarding mode where the interface is immediately put into the forwarding state
upon linkup without waiting for the timer to expire.
spanning-tree portfast [disabled]
Parameters
COST
Specifies the external cost of interface. Valid values are from 0 to 200000000 and 0
means auto.
Default
The default port cost is calculated by port speed.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 8
Usage Guideline
This command is used to configure the path cost between MST regions from the
transmitting Bridge to the CIST Root Bridge.
Example
This example shows how to configure the external path cost.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#interface tenGigabitEthernet 1/0/1
DXS-3600-32S(config-if)#spanning-tree externalcost 22
Success
DXS-3600-32S(config-if)#
disabled
Specifies to disable the portfast on the interface.
Default
The default vaule is disabled.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 8
Usage Guideline
You should use this command only with interfaces that connect to end stations;
otherwise, an accidental topology loop could cause a data-packet loop and disrupt
the switch and network operation.
An interface with portfast mode enabled is moved directly to the spanning-tree
forwarding state when linkup occurs without waiting for the standard forward-time
delay.
Example
This example shows how to configure the portfast state.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#interface tenGigabitEthernet 1/0/1
DXS-3600-32S(config-if)#spanning-tree portfast
Success
DXS-3600-32S(config-if)#
