CHIPENET-MIB

All MIBs › CHIPENET-MIB

Category: Network Interfaces, Vendor: 3Com

Description: Manages Chipcom (3Com) Ethernet interface configuration and traffic statistics on modular hub and switch platforms.

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 CHIPENET-MIB?

CHIPENET-MIB manages Ethernet interface configuration and traffic statistics on Chipcom (3Com) modular hub and switch platforms. It exposes a per-network-ID Ethernet statistics table covering received/transmitted frame and octet counts, multicast/broadcast frame counts, and a range of Ethernet error counters such as oversized frames, alignment errors, FCS errors, runts, and local collisions. This makes it directly useful for hardware-level link health monitoring: rising FCS/alignment errors or runts on a given Ethernet segment point to a cabling or NIC problem, while a jump in local collisions suggests a duplex mismatch or overloaded segment. It supplements the standard IETF Ethernet-like interface/RMON statistics conventions with Chipcom-specific per-net counters. It is deployed on legacy Chipcom/3Com Ethernet hub and switch chassis in campus LAN environments. Engineers can download the CHIPENET-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CHIPENET-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 administrator would poll olEnetStatsTable/olEnetStatsEntry, keyed by olEnetStatsNetID, to compare olEnetStatsFramesRcvdOks and olEnetStatsOctetsRcvdOks against error counters like olEnetStatsFCSErrors, olEnetStatsAlignmentErrors, and olEnetStatsRunts. A sustained rise in olEnetStatsFCSErrors or olEnetStatsRunts on a particular network segment typically signals a bad cable or failing transceiver, while a rise in olEnetStatsLocalColls suggests a duplex mismatch or an overloaded shared segment. olEnetStatsFrameTooLongs would flag devices sending oversized frames, useful for catching a misconfigured jumbo-frame host.

What Can Be Monitored

Ethernet frame/octet counters
multicast/broadcast frame counts
FCS and alignment errors
runt and oversized frame counts
local collision counts
