Description: Provides Cisco-defined extensions to the standard SNMP systemGroup, adding system-level management information for Cisco devices.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring CISCO-SYSTEM-MIB with a free 30-day trial of IPNetwork Monitor.

What Is CISCO-SYSTEM-MIB?

CISCO-SYSTEM-MIB is a Cisco Systems, Inc. proprietary MIB defining Cisco-specific extensions to the standard systemGroup (RFC 1907). Its objects cover clock date/time and a lost-on-reboot flag, location country, summer-time (DST) status/offset and recurring start/end rules, standard/summer time-zone GMT offsets, a scheduled-reset time/action/reason, SNMP-authentication-failure address type/address, a notifications-enable flag, and a system-clock-changed notification. As a configuration/status MIB it lets an administrator confirm a Cisco device's clock/timezone/DST configuration and watch for SNMP authentication failures. It is deployed on Cisco Systems network equipment. Engineers can download the CISCO-SYSTEM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-SYSTEM-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • Cisco Systems network equipment

Monitoring Examples

An administrator checks csySummerTimeStatus and csyClockDateAndTime to confirm daylight-saving and clock configuration on a Cisco device.

What Can Be Monitored

  • system clock/timezone configuration and SNMP auth-failure events

How to Use in IPNetwork Monitor

Example using csySnmpAuthFail OID:

Select a Cisco network equipment (systemGroup extensions) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type csySnmpAuthFail into the Find box to locate it in the OID tree, then select it and click OK. The total number of SNMP messages received by the SNMP engine that were not properly authenticated. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
