Port Status and Configuration

Viewing Port Status and Configuring Port Parameters

Syntax:

show running-config

Displays the running-config file. The broadcast limit setting

appears here if enabled. If the setting is not also saved to the

startup-config file, rebooting the switch returns broadcast

limit to the setting currently in the startup-config file.

For example, the following command enables broadcast limiting of 1 percent

of the traffic rate on the selected port on the switch:

ProCurve(int B1)# broadcast-limit 1

For a one Gbps port this results in a broadcast traffic rate of ten Mbps.

Configuring ProCurve Auto-MDIX

Copper ports on the switch can automatically detect the type of cable config-

uration (MDI or MDI-X) on a connected device and adjust to operate appro-

priately.

This means you can use a “straight-through” twisted-pair cable or a “cross-

over” twisted-pair cable for any of the connections—the port makes the

necessary adjustments to accommodate either one for correct operation. The

following port types on your switch support the IEEE 802.3ab standard, which

includes the “Auto MDI/MDI-X” feature:

■ 10/100-TX xl module ports

■ 100/1000-T xl module ports

■ 10/100/1000-T xl module ports

Using the above ports:

■ If you connect a copper port using a straight-through cable on a switch to

a port on another switch or hub that uses MDI-X ports, the switch port

automatically operates as an MDI port.

■ If you connect a copper port using a straight-through cable on a switch to

a port on an end node, such as a server or PC, that uses MDI ports, the

switch port automatically operates as an MDI-X port.

ProCurve Auto-MDIX was developed for auto-negotiating devices, and was

shared with the IEEE for the development of the IEEE 802.3ab standard.

ProCurve Auto-MDIX and the IEEE 802.3ab Auto MDI/MID-X feature are

completely compatible. Additionally, ProCurve Auto-MDIX supports opera-

tion in forced speed and duplex modes.
