Description: Monitors CPU and memory resource utilization per module on Cisco CBS series small business managed switches.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CBS-MODULE-RESOURCES-MIB?

CBS-MODULE-RESOURCES-MIB is a Crossbeam Systems XOS MIB (again, Crossbeam rather than Cisco despite the naming) that monitors CPU and memory resource utilization for individual processing modules within an XOS chassis. It exposes per-module CPU speed, core count, and load/utilization averages over 1/5/15-minute windows, along with per-module memory utilization tables. This is squarely a software/hardware performance-monitoring MIB, tracking CPU load and memory pressure on each blade/module so operators can detect overloaded modules before they impact packet-processing performance, and it includes traps for resource-threshold events. It is a standalone Crossbeam vendor MIB, independent of IETF standard host-resources MIBs. It's used by network security operations teams running Crossbeam XOS chassis to track per-module compute headroom in multi-blade security service deployments. Engineers can download the CBS-MODULE-RESOURCES-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CBS-MODULE-RESOURCES-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

  • Crossbeam Systems XOS security appliance chassis (per-module blades)

Monitoring Examples

An administrator polls cbsModuleCPULoadTable entries, cbsModuleCPULoad1, cbsModuleCPULoad5, and cbsModuleCPULoad15, to track short- and long-term CPU load trends for each module. cbsModuleCPUUtil1/5/15 give percentage-based utilization for easier threshold alerting, while cbsModuleCPUSpeed and cbsModuleCPUCount provide the module's compute capacity for context. cbsModuleMemoryTable is checked in parallel; a module showing sustained high CPU load alongside climbing memory utilization signals it needs a workload rebalance, and cbsModuleResourceTraps would fire proactively when a threshold is crossed.

What Can Be Monitored

  • per-module CPU load (1/5/15 min)
  • per-module CPU utilization percentage
  • CPU speed and core count
  • per-module memory utilization
  • resource threshold trap events

How to Use in IPNetwork Monitor

Example using cbsModuleSDP0OutPkts OID:

Select a Crossbeam Systems XOS security appliance 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 cbsModuleSDP0OutPkts into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of outbound packets on SDP0 (SPA data path 0). 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 Counter64-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.
