Configuring Optional Interface Features - Cisco Catalyst 4500 Series Software Configuration Manual

This feature is only available when a DOM capable transceiver is present and configured for monitoring.
Note
The frequency at which the sensor information is refreshed depends on default values configured in the
transceiver SEEPROM (Serial Electrically Erasable Programmable Read Only Memory).
Note For details on transceiver module compatibility, refer to this URL:

Speed and Duplex Mode Configuration Guidelines
You do not configure the client device for autonegotiation. Instead, you configure the switch with the
Note
speed, or range of speeds, that you want to autonegotiate.
You can configure the interface speed and duplex mode parameters to auto and allow the Catalyst 4500 series switch to
negotiate the interface speed and duplex mode between interfaces. If you decide to configure the interface speed and duplex
commands manually, consider the following:
• If you enter the no speed command, the switch automatically configures both interface speed and duplex to auto.
• When you set the interface speed to 1000 (Mbps) or auto 1000, the duplex mode is full duplex. You cannot change the
duplex mode.
• If the interface speed is set to 10 or 100, the duplex mode is set to half duplex by default unless you explicitly configure it.
