Configuring Port Speed and Duplex

To configure the port speed—whether 10Mbps or 100Mbps—use the following commands:

CORIOLIS5500(config) interface fastethernet 2/3

CORIOLIS5500(config−int) speed 100

CORIOLIS5500(config−int) duplex full

The auto command can be used when the port on the other side is manually set. Links should not be configured with the auto setting on both devices connecting the links because both sides will try to determine the speed on the other side of the link and neither will agree.

You can change the port duplex from full duplex to half duplex, as shown in the following commands:

CORIOLIS8500(config) interface fastethernet 0/1

CORIOLIS8500(config−int) speed auto

CORIOLIS8500(config−int) duplex half

Enabling SNMP Contact

To set the SNMP contact for RMON support, configure your switch with a contact name, location, and chassis identification to make the device easily identifiable by an SNMP management station. You can set the SNMP system contact, location, serial number, and, most importantly, the community that is the same as the community configured on your SNMP management station. You can configure these items as shown here in the same order as discussed, from the Global Configuration mode prompt:

CORIOLIS8500(config) snmp−server contact Joe Snow

CORIOLIS8500(config) snmp−server location Coriolis Wiring Closet

CORIOLIS8500(config) snmp−server chassis−id 987654321

CORIOLIS8500(config) snmp−server community coriolis

Configuring a Set/Clear−Based CLI Switch

In this section, you’ll walk through the basic configuration of the Set/Clear

command−based CLI switches. Although these tasks are not all mandatory, completing them will help you to better manage your switches.

Logging On to a Switch

To begin configuring your switch, do the following:

1.Connect the console cable and connector to a terminal or PC and power on the switch. The switch will then go through its initial POST, which runs diagnostics and checks for the reliability of the switch components.

2.Once the POST has completed successfully, the initial prompt should show a User EXEC mode prompt:

Enter Password:

3.No password has been configured at this point, so just press the Enter key to continue.

4.Cisco switches have two levels of access by default: User EXEC mode and Privileged EXEC mode. User EXEC mode will allow you to do some basic tasks, such as show the port or VLAN information. To get more advanced configuration options, you will need to enter Privileged EXEC mode. Use the following command to enter Privileged EXEC mode:
