Description: Manages ZyXEL DHCP server operation including address pools, leases, and static bindings for IP allocation.
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 ZYXEL-DHCP-SERVER-MIB?
ZYXEL-DHCP-SERVER-MIB is a ZyXEL proprietary MIB covering the DHCP server subtree, managing DHCP server operation including address pool definitions, active lease tracking, and static IP-to-MAC bindings used for automatic IP address allocation to clients. Its data spans configuration (pool ranges, static bindings) and operational state (current leases) rather than physical hardware sensors. In monitoring terms it is used to verify DHCP server software health -- for example detecting when an address pool is nearing exhaustion (no more leases available) or confirming that expected static bindings are correctly assigned -- which is a service-availability concern rather than a hardware fault concern. It conceptually parallels the IETF DHCP-SERVER-MIB (RFC 2618-family) structure even though implemented as a ZyXEL-specific tree. It is typically deployed on ZyXEL gateway/router devices acting as the DHCP server for a small-to-medium office or branch LAN, and administrators typically load its definitions into a ZYXEL-DHCP-SERVER-MIB MIB Browser session to inspect pool and lease objects.
IPNetwork Monitor allows you to monitor SNMP objects defined in ZYXEL-DHCP-SERVER-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
- ZyXEL gateway/router (DHCP server)
Monitoring Examples
No object or table names were provided in sample_objects for this module, so specific polling targets cannot be confirmed from the given data. Conceptually, an operator would poll the DHCP server's lease table to check the count of active leases against the configured pool size, catching a pool nearing exhaustion before new clients fail to obtain an address. Because sample_objects is empty, no invented object names are given here.
What Can Be Monitored
- DHCP address pool utilization
- active lease count
- static IP-to-MAC bindings
