Where to Go Next

If the default configuration is satisfactory, the switch module does not need further configuration. You can use any of these management options to change the default configuration:

•Using the Device Manager

Access the device manager through a web browser from anywhere in your network. Follow these steps:

a.Launch a web browser on your PC or workstation.

b.Enter the switch module IP address in the web browser, and press Enter. The device manager page appears.

c.Use the device manager to perform basic switch module configuration and monitoring. Refer to the device manager online help for more information.

•Using the CLI

The switch module CLI is based on Cisco IOS software and enhanced to support desktop-switching features. You can fully configure and monitor the switch module from the CLI. You can access the CLI either by connecting your management station directly to the switch module console port or by using Telnet from a remote management station. Refer to the switch module command reference on Cisco.com for more information.

•Using SNMP

You can use SNMP management applications such as CiscoWorks Small Network Management Solution (SNMS) to configure and manage the switch module. You also can manage it from an SNMP-compatible workstation that is running platforms such as HP OpenView or SunNet Manager.
