NETGEAR 8800 Chassis Switch CLI Manual If you choose to keep the default setting for Telnet-the default setting is enabled-the switch returns the following interactive script: Since you have chosen less secure management methods, please remember to increase the security of your network by taking the following actions: * change your admin password * change your SNMP public and private strings * consider using SNMPv3 to secure network management traffic In addition, you can return to safe defaults mode by issuing the following command: configure safe-default-script If you return to safe defaults mode, you must answer the questions presented during the interactive script. For more detailed information about safe defaults mode, see the section "Safe Defaults Setup Method" in the NETGEAR 8800 User Manual. Example With administrator privilege, the following command enables Telnet services on the switch: enable telnet enable watchdog enable watchdog Description Enables the system watchdog timer. Syntax Description This command has no arguments or variables. Default Enabled. Usage Guidelines The watchdog timer monitors the health of the switch hardware and software events. For example, the watchdog timer reboots the switch if the system cannot reset the watchdog timer. This is caused by a long CPU processing loop, any unhandled exception, or a hardware problem with the communication channel to the watchdog. In most cases, if the watchdog timer expires, the switch captures the current CPU status and posts it to the console and the system log. In some cases, if the problem is so severe that the switch is unable to perform any action, the switch reboots without logging any system status information prior to reboot. This command takes affect immediately. Chapter 3. Commands for Managing the Switch | 109
