Ethernet Port Configuration Introduction 57
duplex and can be configured to operate in full (full duplex) or auto
(auto-negotiation) mode.
The port defaults to auto (auto-negotiation) mode.
Setting Speed on the Ethernet Port
Use the following command to set the speed of the Ethernet port. If the speed is set
to auto-negotiation mode, the local and peer ports will automatically negotiate the
port speed.
Perform the following configuration in Ethernet Port View.
Note that 10/100BASE-T Ethernet ports support 10Mbps, 100Mbps and
auto-negotiation, which can be set as required. Gigabit Ethernet ports support
1000Mbps and can be configured to operate at 1000 (1000Mbps) or auto
(auto-negotiation) speed.
By default, the speed of the port set to auto mode.
Setting the Cable Type for the Ethernet Port
Ethernet ports support straight-through and cross-over network cables. Use the
following command to configure the cable type.
Perform the following configuration in Ethernet Port View.
By default, the cable type is auto (auto-recognized). That is, the system can
automatically recognize the type of cable connecting to the port.
Enabling/Disabling Flow Control for the Ethernet Port
After flow control is enabled in both the local and the peer Switch, if congestion
occurs in the local Switch, the Switch will inform its peer to pause packet sending. In
this way, packet loss is reduced. The flow control function of the Ethernet port can be
enabled or disabled using the following command.
Perform the following configuration in Ethernet Port View.
By default, Ethernet port flow control is disabled.
