10/100M Fast Ethernet Port Commands
The Ethernet subsystem allows you to configure and monitor the 10/100M fast Ethernet port that
connects to the backplane.
6.1
10/100M Auto-Sensing Ethernet Overview
The line card’s rear Ethernet port is auto-sensing and supports connections to a 10 or 100Mbps Ethernet. Connect
to the EEC’s Ethernet port in order to connect to the line card’s rear Ethernet port. There are two key factors in
connecting to a peer’s Ethernet port: speed and duplex mode. In a 10/100Mbps fast Ethernet, the speed can be
10Mbps or 100Mbps and the duplex mode can be half or full. Auto-negotiation allows one Ethernet port to
negotiate with a peer to obtain the optimal connection speed and duplex mode automatically.
When auto-negotiation is turned on, the line card negotiates with the peer’s Ethernet port automatically to
determine the optimal connection speed and duplex mode. If the peer’s Ethernet port does not support auto-
negotiation or turns off this feature, the line card determines the connection speed by detecting the signal on the
cable and using half-duplex mode. When the line card’s auto-negotiation is turned off, the Ethernet port uses the
pre-configured speed and duplex mode settings when making a connection, thus requiring you to check the
settings of the peer’s Ethernet port in order to connect.

Commands
6.2.1 Set
Auto
Command
Syntax:
192.168.1.1 ethernet> set auto <ON/OFF>
where
<ON/OFF> = on or off
This command sets the auto-negotiation of the Ethernet port either on or off.
6.2.2
Set Duplex Command
Syntax:
192.168.1.1 ethernet> set duplex <mode>
where
<mode> = full or half
This command sets the duplex mode used when auto-negotiation is turned off.
