Description: Manages DHCP server configuration and lease allocation on Cabletron/Enterasys FastPath switching 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 CT-FASTPATH-DHCPSERVER-MIB?

This Enterasys (Cabletron) MIB manages the built-in DHCP server configuration on FastPath switching platforms, covering scope/pool definitions and lease-allocation behavior for clients served directly by the switch. It exposes objects for configuring DHCP address pools/scopes, lease durations, and related server parameters, along with data reflecting current lease allocation state. Its monitoring value lies in confirming the DHCP server's configuration and operational status on the switch - such as whether the service is enabled and how address pools are being consumed - rather than any hardware sensor data. It depends on the standard DHCP protocol model for its object definitions and sits within Enterasys's broader FastPath MIB family. It is typically deployed on Enterasys/Cabletron FastPath switches acting as a local DHCP server for a small network segment, monitored by administrators for address-pool exhaustion or misconfiguration. Engineers can download the CT-FASTPATH-DHCPSERVER-MIB file directly to load it into their MIB browser.

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

  • Enterasys/Cabletron FastPath switch

Monitoring Examples

No sample object names were supplied for this MIB, so specific OIDs cannot be cited here. Based on its stated purpose, an administrator would be expected to poll DHCP pool/scope configuration and lease-count objects to detect an exhausted address pool or a misconfigured scope preventing clients from obtaining an address. This is a general characterization rather than a citation of confirmed object names.

What Can Be Monitored

  • DHCP scope/pool configuration
  • lease allocation status
  • DHCP server enabled/operational state

How to Use in IPNetwork Monitor

Example using ctAgentDhcpServerAutomaticBindingsNos OID:

Select an Enterasys/Cabletron FastPath switch (DHCP server) 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 ctAgentDhcpServerAutomaticBindingsNos into the Find box to locate it in the OID tree, then select it and click OK. The no. of IP addresses that have been assigned automatically. 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.
