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 HPN-ICF-LswDHCP-MIB?
HPN-ICF-LswDHCP-MIB is an HPE/H3C Comware ICF private MIB (the "Lsw" prefix denoting LAN switch scope) that manages DHCP server, relay, and snooping configuration and lease information on switch platforms. No module description or object list is populated in this snapshot, but a DHCP MIB of this scope typically exposes server/relay/snooping enable scalars, a lease table showing assigned client IP-to-MAC bindings, and DHCP snooping binding tables used to block spoofed or rogue DHCP traffic on access ports. Its monitoring role is software/service-oriented: confirming DHCP services are enabled as intended and that the snooping binding table reflects legitimate client leases, important for both address management and Layer 2 security. An unexpectedly empty or stale lease/binding table would point to a DHCP service outage or a snooping misconfiguration on the switch. It complements standard IETF DHCP-related MIBs with switch-specific detail and is deployed on HPE/H3C Comware Layer 2/3 switches providing DHCP services to attached clients. Network engineers evaluating or troubleshooting this functionality can download the HPN-ICF-LswDHCP-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in HPN-ICF-LswDHCP-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
- HPE/H3C Comware LAN switches
Monitoring Examples
No object names are available in this snapshot, so a specific polling scenario cannot be given with confidence. Typically an operator would poll the DHCP snooping binding table for client IP/MAC/port bindings and the lease table to confirm addresses are assigned correctly, where a binding table that stops updating despite active client traffic suggests DHCP snooping or the DHCP service itself has stopped functioning.
What Can Be Monitored
- DHCP server/relay/snooping enable status
- DHCP lease/binding table entries
