What Is HH3C-DHCPSNOOP-MIB?
HH3C-DHCPSNOOP-MIB is an H3C enterprise MIB for the DHCP Snooping security feature, which inspects DHCP traffic on switch ports to distinguish trusted uplinks from untrusted client-facing ports and builds a binding table of legitimate IP-to-MAC-to-port leases. It exposes configuration-oriented data: per-port trust state, snooping enable/disable status, and the resulting DHCP binding entries used to filter rogue DHCP servers and spoofed traffic. Its monitoring value is largely a software/feature-status one, letting an admin confirm that DHCP snooping is enabled where expected and inspect the binding table to verify which hosts have valid, snooped DHCP leases, helping detect misconfigured trust settings or clients being blocked unexpectedly. It works alongside standard DHCP MIBs and is often paired with IP Source Guard/dynamic ARP inspection features that reuse the snooping binding table. Typical deployment is on H3C access-layer switches in enterprise or campus networks needing DHCP-based network access security. Engineers can download the HH3C-DHCPSNOOP-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-DHCPSNOOP-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
- H3C access/edge switch
Monitoring Examples
No specific object names were sampled for this MIB, so exact identifiers can't be cited, but consistent with its stated purpose (a DHCP Snooping profile) it would expose per-port trust-state settings and a binding table of learned IP/MAC/port leases. An admin would typically check whether snooping is enabled on client ports and review the binding table to confirm no unauthorized DHCP server is answering on an untrusted port.
What Can Be Monitored
- DHCP snooping enable/disable status
- per-port trust state
- DHCP binding table entries
- detected rogue DHCP activity
