Configuring Denial of Service (DoS) Chapter 5 Configuring Simple Network Management Protocol (SNMP) Enter the reload_value as the object used to control apSnmpExtReloadSet, providing the SNMP-based reboot. When the object is set to 0, an SNMP reboot is not allowed. When the object is set to a value from 1 to 2147483646, that value is written to the apSnmpExtReloadSet object to cause a reboot. When the reload_value object is set to 2147483647, a reboot may be caused with any write value to apSnmpExtReloadSet. For security purposes, this object always returns 0 when read. Note When you reboot the CSS using the snmp reload-enable command, the CSS does not prompt you to save the running-config file or to verify that you want to reboot. Before you enter this command, be sure that you have saved any changes to your running-config file and that you want to reboot the CSS. For example: (config)# snmp reload-enable To prevent users from rebooting the CSS using SNMP (default behavior), enter: (config)# no snmp reload-enable Configuring Denial of Service (DoS) You can configure special enterprise traps to notify the trap host of Denial of Service (DoS) attacks on your system. You can also use the CLI to display detailed information about DoS attacks and reset the DoS statistics for your CSS to zero. Ensure you first enable SNMP enterprise traps using the snmp trap-type enterprise command before you configure the CSS to generate SNMP enterprise traps when a DoS attack event occurs. For information, see the "Configuring SNMP Enterprise Traps" section.
