See other chapters in the AT-8800 Series Switch Software Reference for more information on how to:

■Use the logging facility to monitor network activity and to select and display the results (see the Logging Facility chapter).

■Use SNMP to manage the switch remotely (see the Simple Network Management Protocol (SNMP) chapter and Appendix C: SNMP MIBs).

■Use the command line to create, delete and modify configuration scripts (see the Scripting chapter).

■Set up triggers to automatically run specified scripts at specified times, or at specified events (see the Trigger Facility chapter).

■Use NTP to synchronise your router’s time clock with those of other network devices (see the Network Time Protocol (NTP) chapter).

■Use software to test whether the router’s hardware functions correctly (see the Test Facility chapter).
