Category: VLAN and Bridging, Vendor: Cabletron/Enterasys

Description: Manages Cabletron ELS100 series entry-level switch configuration including port, VLAN, and spanning tree settings.

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 CT-ELS100-MIB?

CT-ELS100-MIB is a vendor MIB from Cabletron Systems for its ELS100 series entry-level Ethernet switches, covering device configuration such as port settings, VLAN assignment, and spanning tree parameters. It sits in the configuration category for a small fixed-configuration switch product line, exposing the basic Layer 2 switching controls typical of an entry-level managed switch. Given the product class, monitoring value is mainly around confirming port and VLAN configuration state and spanning tree operation as indicators of correct network segmentation, rather than rich hardware sensor telemetry (which this low-end product line generally lacks). No module description or dependency detail was available in the source, but Cabletron switch MIBs of this era typically build on the standard Bridge MIB (dot1dBase) and Interfaces MIB (IF-MIB) for underlying port and bridging context. It is typically deployed in small-office or wiring-closet environments using Cabletron/Enterasys ELS100 switches for basic managed Ethernet connectivity. Network engineers evaluating or troubleshooting this functionality can download the CT-ELS100-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CT-ELS100-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

  • Cabletron ELS100 series Ethernet switches

Monitoring Examples

No sample object names beyond a generic IMPORTS clause were provided for this module, so specific table or object names cannot be cited with confidence. In general, an administrator would use this MIB's port, VLAN, and spanning-tree configuration objects to confirm a port's VLAN assignment and spanning-tree state, which would reveal a misconfigured port causing a device to land on the wrong VLAN or a spanning-tree loop forming after a topology change.

What Can Be Monitored

  • port configuration
  • VLAN assignment
  • spanning tree state
  • MAC address management
