Dell PowerConnect 3524 User Manual

Spanning-Tree Commands 363
Command Mode
Interface Configuration (Ethernet, port-channel) mode.
User Guidelines
There are no user guidelines for this command.
Example
The following example configures the spanning priority on Ethernet port 1/e15 to 96.
spanning-tree portfast
The spanning-tree portfast Interface Configuration mode command enables PortFast mode. In PortFast
mode, the interface is immediately put into the forwarding state upon linkup without waiting for the
standard forward time delay. Use the no form of this command to disable PortFast mode.
Syntax
• spanning-tree portfast [auto]
• no spanning-tree portfast
• auto — Specifies that the software waits for 3 seconds (With no BPDUs received on the interface)
before putting the interface into the PortFast mode.
Default Configuration
PortFast mode is disabled.
Command Mode
Interface Configuration (Ethernet, port-channel) mode.
User Guidelines
This feature should be used only with interfaces connected to end stations. Otherwise, an accidental
topology loop could cause a data packet loop and disrupt device and network operations.
Example
The following example enables PortFast on Ethernet port 1/e15.
Console(config)# interface ethernet 1/e15
Console(config-if)# spanning-tree port-priority 96
Console(config)# interface ethernet 1/e15
Console(config-if)# spanning-tree portfast
