Description: Monitors Xedia Corp. Ethernet interface statistics, collision counts, and MAC-layer error rates.

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 XEDIA-ETHERNET-MIB?

The XEDIA-ETHERNET-MIB is a Xedia Corporation proprietary MIB (Xedia made multiservice access routers) that extends the IETF Ethernet-Like Interface MIB with additional Ethernet MAC-layer statistics for Xedia devices. It exposes an extended Ethernet statistics table covering transmit and receive error conditions beyond what the standard dot3StatsTable provides. Its monitoring focus is squarely on interface hardware health: it captures underflow, no-carrier, carrier-loss, jabber-timeout, and collision counters on the transmit side, and runt, dribble, overflow, and descriptor-error counters on the receive side, giving fine-grained visibility into a failing NIC, duplex mismatch, or cabling fault. It explicitly extends the IETF Ethernet-Like Interface MIB (RFC 1650/2665, the dot3 MIB), on which it is directly dependent for base interface identification. It was deployed on Xedia multiservice access routers in enterprise and service-provider edge networks running Ethernet uplinks. Engineers can download the XEDIA-ETHERNET-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in XEDIA-ETHERNET-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.

Monitoring Examples

An engineer polls xdot3StatsTable/xdot3StatsEntry for a given Ethernet interface and watches xdot3StatsOutTotalCollisions and xdot3StatsInTotalCollisions for a rising trend, which usually indicates a duplex mismatch with the connected switch port. They also check xdot3StatsOutJabberTimeouts and xdot3StatsInRunts, where nonzero jabber timeouts point to a malfunctioning NIC on the segment and rising runt counts suggest a cabling or connector fault.

What Can Be Monitored

Ethernet collision counters
carrier loss/underflow errors
jabber timeout events
runt/dribble/overflow frame counts

How to Use in IPNetwork Monitor

Example using xdot3StatsOutUnderflows OID:

Select a Xedia multiservice access router 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 xdot3StatsOutUnderflows 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. It reports a count of frames not transmitted on a particular interface because of underflow. 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.

OIDs

INT xdot3ConfigMedia	1.3.6.1.4.1.838.3.3.1.2.1.3	INTEGER	read-only	The media type of the interface. The value 'tx(1)' indicates copper, 'fx(2)' indicates 850 nm multi-mode fiber, 'sx(3)' indicates 850 nm multi-mode fiber and lx(4) indicates 1300 nm single-mode or multi-mode fiber.

Capture effect occurs when two stations transmit in such a way that, because of collision backoff, one station captures the channel for an unfair amount of time (and the line may remain idle for a long time after that station stops transmitting because of the second station increasing its backoff time.) The value of 'enabled(1)' indicates the enhanced algorithm will be use. The value 'disabled(2)' is the default and indicates the standard backoff algorithm is used.
