10/100M Fast Ethernet Port Commands 8-1
The Ethernet subsystem allows you to configure and monitor the 10/100M fast Ethernet port.
8.1 10/100M Auto-Sensing Ethernet
The IES-1000 supports 10/100Mbps auto-negotiating Ethernet. There are two factors related to the connection of
two Ethernet ports: speed and duplex mode. In a 10/100Mbps fast Ethernet, the speed can be 10Mbps or 100Mbps
and the duplex mode can be half duplex or full duplex. The auto-negotiation capability makes one Ethernet port
able to negotiate with a peer automatically to obtain the optimal connection speed and duplex mode.
When auto-negotiation is turned on, the Ethernet port of the IES-1000 negotiates with the peer Ethernet port on
the Ethernet cable automatically to determine the optimal connection speed and duplex mode. If the peer Ethernet
port does not support auto-negotiation or turns off this feature, the IES-1000 determines the connection speed by
detecting the signal on the cable and using half duplex mode. When the IES-1000’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 Ethernet port in order to connect.
8.2 Ethernet Commands
8.2.1 Set Auto Command
Syntax:
192.168.1.1 ethernet> set auto
where
= on or off
This command sets the auto-negotiation of the Ethernet port to either on or off.
8.2.2 Set Duplex Command
Syntax:
192.168.1.1 ethernet> set duplex
where
= full or half
This command sets the duplex mode used when auto-negotiation is turned off.
