TPLINK-DHCPFILTERING-MIB

Description: Manages TP-Link switch DHCP packet filtering rules and unauthorized server blocking.

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.

TPLINK-DHCPFILTERING-MIB is a TP-Link private MIB for configuring DHCP packet filtering on their managed switches, a security feature that blocks unauthorized or rogue DHCP server responses from being forwarded on untrusted ports. It exposes configuration objects for enabling DHCP filtering globally and per port, and for designating which ports are trusted to relay legitimate DHCP server traffic. Rather than hardware sensor data, its monitoring value is on the software/configuration-status side - confirming whether DHCP filtering is enabled and which ports are trusted, helping an operator verify protection against rogue DHCP servers is active as intended. It builds on standard DHCP relay/snooping concepts and typically complements TPLINK-DHCPSNOOPING-MIB in the same product line. It is deployed on TP-Link managed switches in networks where preventing rogue DHCP servers is a security requirement. Engineers can download the TPLINK-DHCPFILTERING-MIB file directly to load it into their MIB browser.

Specific table/object names were not present in the provided sample, so a fully concrete example cannot be grounded in real identifiers; based on the module description, an administrator would check the per-port DHCP filtering enable/trust configuration to confirm that only designated uplink ports are trusted to pass DHCP server traffic, and that filtering is active on access ports to block rogue DHCP responses.
