Description: Provides SNMP management for Excel3 series managed Ethernet switches including port and VLAN control.

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 EXCEL3-SWITCH-MIB?

EXCEL3-SWITCH-MIB is an Excel Switching Corporation (enterprise OID 1751, telephony switch vendor later Lucent) proprietary MIB reporting node/comm-card/VoIP-DSP hardware status. Its objects cover node identifier/location/current-time, current-node reference, node count, a node table (logical/physical ID, type), a comm-card table (slot index, operational state, reset reason, config status, confidence-test result, action, action time), and a VoIP-DSP table (slot number, DSP index, installed flag). As a hardware-status MIB it lets an administrator confirm comm-card operational state and VoIP DSP resource installation on an Excel Switching telephony switch. It is deployed on Excel Switching Corporation (Lucent) telephony switches. Engineers can download the EXCEL3-SWITCH-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EXCEL3-SWITCH-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

  • Excel Switching Corporation (Lucent) telephony switches

Monitoring Examples

An administrator checks excelCommCardOperState and excelCommCardResetReason to diagnose a faulty communications card on an Excel Switching telephony switch.

How to Use in IPNetwork Monitor

Example using excelSpanBipolarViolation OID:

Select an Excel Switching Corporation (Lucent) telephony switch, VoIP DSP 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 excelSpanBipolarViolation 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 Bipolar Violations that have occurred on this span since the span became active or since the last request. 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 between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
