Configuring Auto-Negotiation
Auto-negotiation is an optional feature of the Fast Ethernet
standard that allows two devices on a common segment to
communicate their capabilities, allowing the devices to
determine their highest common speed and best
communication parameters. The two devices involved in
auto-negotiation are the network card installed in your
computer and the IntraSwitch to which it is connected.
Communication between the two devices occurs when
both devices are powered on, the cable connection
between them is valid, and the network operating system
software is running.
Options Negotiated
❏ Ethernet type (100Base-TX Fast Ethernet or
10Base-T Ethernet)
❏ Duplex mode (half or full)

module for auto-negotiation:
▲ Important: Only the 10/100TX port and 10/
100 MII ports are capable of auto-negotiation.
