Configuring the Switch 61

General Configuration Information

Your switch has predefined features and setup configuration.

Auto-negotiation allows a device to advertise modes of operation and share information with

another device that shares a point-to-point link segment. This automatically configures both

devices to take maximum advantage of their abilities.

Auto-negotiation is performed completely within the physical layers during link initiation, without

any additional overhead to either the MAC or higher protocol layers. Auto-negotiation allows the

ports to do the following:

• Advertise their abilities

• Acknowledge receipt and understanding of common modes of operation that both devices

• Reject the use of operational modes that are not shared by both devices

• Configure each port for the highest-level operational mode that both ports can support

If connecting a port of the switch to the network interface card (NIC) of a workstation or server

that does not support auto-negotiation or is not set to auto-negotiation, both the switching port

and the NIC must be manuallyet with the Web browser interface or CLI commands to the same

speed and duplex mode.

NOTICE: If the station on the other side of the link attempts to auto-negotiate with a port that is

manually configured to full duplex, the auto-negotiation results in the station attempting to operate in half

duplex. The resulting mismatch may lead to significant frame loss. This is inherent in the auto-negotiation

standard.

The following table describes the switch port default settings.
