Description: Manages DS3/T3 interface configuration and performance statistics on Cisco MGX 8200 WAN switch line cards.

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 CISCO-MGX82XX-DSX3-MIB?

CISCO-MGX82XX-DSX3-MIB manages DS3/E3 (T3) physical interface configuration, statistics, and alarm settings on Cisco MGX 8200-series WAN switches, covering service modules such as PXM1, CESM-T3E3, FRSM-VHS, FRSM-2CT3, and SRM-3T3. It exposes line configuration (line type, coding, length), loopback control, FEAC code handling, and alarm/BERT test settings for T3/E3 circuits. Its monitoring value centers on hardware-level line and alarm status: detecting Out-Of-Frame (OOF) conditions, alarm indication signals, loopback state, and bit-error-rate test results that indicate a failing or degraded T3/E3 physical link. It is closely related to, and typically deployed alongside, the standard DS3/E3 MIB (RFC 3896-style dsx3 objects) whose naming conventions it reuses. It is used in legacy Cisco MGX WAN switching environments carrying T3/E3 circuit-emulation, frame relay, and ATM traffic. Engineers can download the CISCO-MGX82XX-DSX3-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-MGX82XX-DSX3-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 MGX 8200 WAN switch (T3/E3 service modules)

Monitoring Examples

An operator would poll cwDsx3ConfigTable (dsx3LineNum, cwDsx3LineType, cwDsx3LineCoding, cwDsx3LineLength) to confirm a T3 line is provisioned correctly for its facility type. Checking dsx3LineOOFCriteria and dsx3LineAIScBitsCheck against actual alarm state would reveal whether the line is experiencing framing errors or AIS conditions. dsx3LineLoopbackCommand and dsx3LineBERTEnable let an admin initiate diagnostic loopback or bit-error-rate tests when troubleshooting a suspect T3/E3 circuit.

What Can Be Monitored

  • T3/E3 line type and coding configuration
  • out-of-frame (OOF) alarm status
  • loopback test state
  • FEAC code transmit/receive
  • bit-error-rate test (BERT) status
  • line length configuration

How to Use in IPNetwork Monitor

Example using dsx3LCVCurrent OID:

Select a Cisco MGX 8200 WAN switch (T3/E3 service modules, legacy) 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 dsx3LCVCurrent 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 Line Code Violations(LCV) encountered by the interface in current 15 minute period. 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.
