Features:
- Status and Counters: Provides access to display screens providing information on switch and port status, network activity, the address tables, and spanning tree operation.
- Switch Management Access Configuration: Provides access to configuration screens that control interaction between the switch and network management, including IP address, SNMP community names and trap receivers, console/serial link parameters, and console passwords.
- Switch Configuration: Provides access to configuration screens that enable you to display the current configuration settings and to customize the configuration of the switch features.
- Event Log: Enables you to read progress and error messages that are useful for checking and troubleshooting switch operation.
- Diagnostics: Provides access to screens for doing Link and Ping connectivity testing, listing the current switch configuration, and to a command prompt for executing system management, monitoring, and troubleshooting commands.
- Reboot Switch: Performs a software reboot of the switch, which clears most temporary error conditions, resets the network activity counters to zero, and resets the system up time to zero. A reboot is required (in one case) to activate a configuration change that has been made.
