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

Configuring the GbE Interconnect Switch using the Command Line Interface
Disabling STP
Use the following command to disable STP on the GbE Interconnect Switch, disable ports
from participating in the spanning tree domain, or to disable bypass on a port:
Command Description
stp disable
{
feature |
bypass <portlist> |
port <portlist>
}
Disables STP on the GbE Interconnect Switch,
disables a port or ports from participating in a
single spanning tree domain, or disables bypass
on a port or ports
Type one of the following in the command:
• feature—Type feature to disable STP
globally for the GbE Interconnect Switch.
• bypass <portlist>—Type bypass and the
port number or numbers to disable bypass
on the specified ports.
• port <portlist>—Type port and the port
number or numbers to disable the port from
participating in the spanning tree domain.
Setting Global and Per Port STP Parameters
The following STP settings can be configured globally on the GbE Interconnect Switch:
• Bridging—Sets the following bridging options:
— Forward delay—Forward delay is the time any port on the GbE Interconnect Switch
spends in the listening state while moving from the blocking state to the forwarding
state. Forward delay values range from 4 to 30 seconds.
— Hello time—Hello time is the interval between two transmissions of Bridge Protocol
Data Units (BPDU) packets sent by the root bridge to tell all other switches that it is
the root bridge. If you set a hello time for the GbE Interconnect Switch, and it is not
the root bridge, the set hello time will be used if and when your GbE Interconnect
Switch becomes the root bridge. The hello time cannot be longer than the maximum
age, otherwise, a configuration error will occur. Hello time values range from 1 to 10
seconds.
— Max age—At the expiration of the maximum age, if a Bridge Protocol Data Unit
(BPDU) has still not been received from the root bridge, the GbE Interconnect
Switch will start sending its own BPDU to all other switches for permission to
become the root bridge. If the GbE Interconnect Switch has the lowest bridge
identifier, it will become the root bridge. Maximum values range from 6 to 40
seconds.
— Priority—The priority number is used in the voting process between switches on the
network to determine which switch will be the root switch. A low number indicates a
high priority, and a higher probability that this GbE Interconnect Switch will be
elected as the root switch. Priority values range from 0 to 65,535. Zero (0) indicates
the highest priority.
