Description: Handles multiple concurrent DHCP client instances on World Wide Packets equipment, tracking per-interface lease state and server selection.

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 WWP-MULTI-DHCP-CLIENT-MIB?

WWP-MULTI-DHCP-CLIENT-MIB is a World Wide Packets (WWP, now Ciena) MIB managing multiple DHCP client instances on WWP Ethernet transport products, allowing several logical interfaces on one device to each independently obtain configuration via DHCP. No specific objects were captured in this extraction, but per its stated purpose it would expose per-client-instance configuration and lease state such as client enable/administrative status, assigned IP address/lease information, and selected DHCP server identity for each interface running a DHCP client. Its monitoring value centers on software/network configuration status: confirming which interfaces successfully obtained a DHCP lease, which server granted it, and detecting an interface stuck without an address due to a failed DHCP exchange. It presumably relates to standard IETF DHCP conventions and WWP's interface/IP-address MIBs, though the specific dependency can't be confirmed without object-level detail. It is deployed in WWP/Ciena LEOS-based Ethernet transport and access equipment where multiple logical interfaces each need independent DHCP-obtained addressing. Engineers can download the WWP-MULTI-DHCP-CLIENT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in WWP-MULTI-DHCP-CLIENT-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

WWP/Ciena LEOS Ethernet transport/access device

Monitoring Examples

No sample objects were provided for this module, so a concrete object/table-level polling scenario can't be honestly constructed here. Based on its stated purpose, an operator would plausibly poll per-DHCP-client-instance status and lease information to confirm each logical interface has successfully obtained an IP address, and would investigate a client instance stuck in a non-bound state as a sign of DHCP server unreachability or a misconfigured client on that interface. Exact object and table names should be confirmed directly from the source MIB before building specific monitoring rules.

How to Use in IPNetwork Monitor

Example using wwpMultiDhcpClientNumber OID:

Select a WWP/Ciena LEOS Ethernet transport/access device (per-interface DHCP-client lease status) 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 wwpMultiDhcpClientNumber into the Find box to locate it in the OID tree, then select it and click OK. The number of dhcp clients (regardless of their current state) present on this system. 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 an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the count changes from its expected baseline, since that would indicate the underlying set of items changed unexpectedly. Click Finish to create the monitor; you can adjust any parameter later.
