Description: Manages Ciena LEOS DHCP client interface configuration, lease state, and IP address assignment.

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-LEOS-DHCP-CLIENT-MIB?

This proprietary Ciena/WWP LEOS MIB manages the DHCP client function on LEOS-based Metro Ethernet switches, used when the device obtains its management IP address dynamically. It exposes configuration data (DHCP client enable/interface binding) and lease-state data (assigned IP, lease timers, server identity) rather than traffic counters or hardware sensors. Monitoring it confirms software/network configuration status, specifically whether the device successfully obtained or renewed a DHCP lease for its management interface, since a failed or expired lease can mean loss of remote management reachability. It depends conceptually on the IETF DHCP protocol standard (RFC 2131) for its client state model, and sits within the WWP-LEOS proprietary MIB family. It is typically deployed on WWP/Ciena Metro Ethernet switches where the management interface is provisioned dynamically rather than with a static IP. Engineers can download the WWP-LEOS-DHCP-CLIENT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in WWP-LEOS-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.

Monitoring Examples

No sample objects were provided for this module in the source data. In general, a DHCP client MIB of this kind exposes a lease-state table with the currently assigned IP address, lease/renewal timers, and the serving DHCP server's identity, which an operator would poll to confirm the management interface still holds a valid lease rather than having reverted to an unreachable fallback address.

What Can Be Monitored

DHCP client enable state
assigned management IP address
lease expiration/renewal time
DHCP server identity
