Configuring Ethernet Ports on Second Generation Devices
The Ethernet ConÞguration window available for Fast Ethernet and Gigabit
Ethernet ports on second generation devices (e.g., 2H252-25R and 2H258-17R)
allows you to both view and set those portsÕ available speed, modes, and ßow
control. All second generation devices support the ctEthernetParameters MIB. All
Ethernet ports that return at least one instance for a query of the
ctEtherSupportedDuplex OID will use the Ethernet ConÞguration window as
shown in Figure 2-16.
All 100Base-TX Fast Ethernet ports can be conÞgured to operate in either standard
Ethernet (10 Mbps) or Fast Ethernet (100 Mbps) mode, and each mode can be
conÞgured to operate in Full Duplex effectively doubling the available wire speed
(from 10 to 20 Mbps in standard Ethernet mode, or from 100 to 200 Mbps in Fast
Ethernet mode). 100Base-FX (Þber) ports can be conÞgured to operate in their
standard 100 Mbps mode, or in Full Duplex mode. 1000Base-SX/LX/CX Gigabit
Ethernet ports are always conÞgured to operate in 1000 Mbps, Full Duplex mode.
This window displays the mode currently in effect on the selected interface, and
provides some information (where it is available) about the interfaceÕs link
partner.
To access the Ethernet ConÞguration Window:
1. From the Chassis View, click to select the port you wish to configure; the Port
Menu will display.
2. Click on Configuration. The Ethernet Configuration window, Figure 2-15, will
appear.
