Chapter 1 Port Physical Characteristics
Configuration
1.1 Configuring the Ethernet Interface
The section describes how to configure the Ethernet interface. The switch supports
the10Mbps Ethernet and the 100Mbps fastEthernet. The detailed configuration is shown
as follows. The step described in section 1.1.1 is mandatory. Steps described in other
sections are optional.
1.1.1 Selecting Ethernet Interface
Run the following command in global configuration mode to enter the Ethernet interface
configuration mode:
Run… To…
interface fastethernet [slot|port ] Enter the fastEthernet interface
configuration mode
interface gigaethernet [slot|port ] Enter the gigabit Ethernet interface
configuration mode.
You can run the show interface fastethernet command to display the state of
fastEthernet interface. You can run the show interface gigaethernet command to
display the state of the gigabit Ethernet interface.
1.1.2 Configuring Rate
The Ethernet rate can be realized through auto-negotiation or configuration on the
interface.
Run the following command to configure the Ethernet rate:
Run… To…
Speed {10|100|1000|auto} Set the rate of fast Ethernet to 10M, 100M, 1000M or
auto-negotiation.
No speed Resume the default settings—auto-negotiation.
Note:
The speed of the optical interface is fixed. For example, the rate of GBIC and GE-FX is
1000M; the rate of FE-FX is 100M. If the auto parameter is behind the speed command,
it means that you can enable the auto-negotiation function on the optical interface.
Otherwise, you cannot enable the auto-negotiation function on the optical interface.
1.1.3 Configuring Flow Control on the Interface
When the interface is in full-duplex mode, the flow control is achieved through the
PAUSE frame defined by 802.3X. When the interface is in half-duplex mode, the flow
control is achieved through back pressure.

flow-control on/off Enable or disable the flow control on the interface.
no flow-control Resume the default settings.
The default settings have no flow control.
