4000 Router Series Layer 2 - LAN Switching Configuration Guide

Step Command Remarks

3. Configure the port priority.

• In STP/RSTP mode:

stp port priority priority

• In MSTP mode:

stp [ instance instance-list ] port priority

priority

The default setting is 128

for all ports.

NOTE:

hen the priority of a port chan

es, the system re-calculates the port role and initiates a state transition.

Configuring the port link type

A point-to-point link directly connects two devices. If two root ports or designated ports are connected

over a point-to-point link, they can rapidly transit to the forwarding state after a proposal-agreement

handshake process.

Configuration restrictions and guidelines

• You can configure the link type as point-to-point for a port that operates in full duplex mode. HP

recommends using the default setting and letting the device automatically detect the port link type.

• The stp point-to-point force-false or stp point-to-point force-true command configured on a port in

MSTP mode is effective on all MSTIs.

• If you configure a non-point-to-point link as a point-to-point link, the configuration might cause a

temporary loop.

Configuration procedure

To configure the link type of a port:

Step Command Remarks

1. Enter system view.

system-view N/A

2. Enter Layer 2 Ethernet

interface view.

interface interface-type

interface-number

N/A

3. Configure the port link type.

stp point-to-point { auto | force-false

| force-true }

By default, the link type is auto

where the port automatically

detects the link type.

Configuring the mode a port uses to recognize and

send MSTP packets

A port can receive and send MSTP packets in the following formats:

• dot1s—802.1s-compliant standard format
