Spanning-Tree Commands
Intel® Blade Server Ethernet Switch Modules SBCEGBESW1 and SBCEGBESW10 CLI Guide 267
Command Modes
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 15.
spanning-tree link-type
The spanning-tree link-type Interface Configuration mode command overrides the
default link-type setting determined by the duplex mode of the port and enables Rapid
Spanning Tree Protocol (RSTP) transitions to the forwarding state. To restore the default
configuration, use the
no form of this command.
Syntax
spanning-tree link-type {point-to-point | shared}
no spanning-tree spanning-tree link-type
Parameters
• point-to-point —Indicates that the port link type is point-to-point.
• shared — Indicates that the port link type is shared.
Default Configuration
The device derives the port link type from the duplex mode. A full-duplex port is
considered a point-to-point link and a half-duplex port is considered a shared link.
Command Modes
Interface Configuration (Ethernet, port-channel) mode
Console(config)# interface ethernet ext.15
Console(config-if)# spanning-tree portfast
