Port Status and Basic Configuration

Viewing Port Status and Configuring Port Parameters

Using the above ports:

If you connect a copper port using a straight-through cable to a port on another switch or hub that uses MDI-X ports, the switch port automati­ cally operates as an MDI port.

If you connect a copper port using a straight-through cable 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.

HP Auto-MDIX was developed for auto-negotiating devices, and was shared with the IEEE for the development of the IEEE 802.3ab standard. HP Auto- MDIX and the IEEE 802.3ab Auto MDI/MID-X feature are completely compat­ ible. Additionally, HP Auto-MDIX supports operation in forced speed and duplex modes.

If you want more information on this subject please refer to the IEEE 802.3ab Standard Reference.

For more information on MDI-X, refer to the appendix titled “Switch Ports and Network Cablesin the Installation and Getting Started Guide for your switch.

Manual Auto-MDIX Override on the Series 2600/2600-PWR and 2800 Switches

This feature is supported only on the Series 2600, 2600-PWR, and 2800 Switches. If you require control over the MDI/MDI-X feature you can set the switch to either of two non-default modes:

Manual MDI

Manual MDI-X

Table 10-1 shows the cabling requirements for the MDI/MDI-X settings.
