ProLiant BL p-Class GbE Interconnect Switch Command Line Interface Reference Guide

Configuring the GbE Interconnect Switch using the Command Line Interface
Enabling STP
Spanning Tree Protocol (STP) can be enabled or disabled at the switch level. Only one
spanning tree domain per GbE Interconnect Switch is supported. You can configure ports to
participate in that spanning tree domain, by enabling or disabling the STP function on a per
port basis. Ports can also be configured in STP bypass mode (fast forward mode) that allows
the port to skip the initial STP states (listening and learning) before enabling it in the
forwarding state.
IMPORTANT: The GbE Interconnect Switch supports mono-Spanning Tree Protocol. Multiple spanning
tree domains are not supported. This means the Spanning Tree Algorithm makes calculations without
considering the VLAN domains to which the ports belong. All ports that have STP enabled fall under
one STP domain.
Use the following command to enable STP on the GbE Interconnect Switch, configure ports
to participate in the spanning tree domain, or to enable bypass on a port.
Command Description
stp enable
{
feature |
bypass <portlist> |
port <portlist>
}
Enables STP on the GbE Interconnect Switch,
enables bypass on a port or ports, or enables a
port or ports to participate in a single spanning
tree domain. Type one of the following in the
command:
• feature—Type feature to enable STP
globally for the GbE Interconnect Switch.
• bypass <portlist>—Type bypass and the
port number or numbers to enable bypass
on the specified ports.
• port <portlist>—Type port and the port
number or numbers to enable the port to
participate in the spanning tree domain.
