10/100M Auto-Sensing Ethernet Ports

The ZyWALL 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 ZyWALL 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
ZyWALL determines the connection speed by detecting the signal on the cable and using half duplex
mode. When the ZyWALL'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.
