TPLINK-IP-SOURCE-GUARD-MIB

Description: Manages TP-Link switch IP source guard port bindings to prevent IP address spoofing.

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-IP-SOURCE-GUARD-MIB is a TP-Link private MIB for configuring IP Source Guard, a port-security feature that filters inbound IP traffic against a table of bound IP/MAC/VLAN/port entries (typically learned via DHCP snooping) to prevent IP address spoofing. It exposes per-port enable configuration and a binding table describing which source IP/MAC combinations are permitted on which ports. Its monitoring focus is configuration/security status - verifying source guard is enabled on access ports and that the binding table accurately reflects legitimate hosts - rather than hardware telemetry. It depends directly on data learned by TPLINK-DHCPSNOOPING-MIB to populate its binding entries. It is deployed on TP-Link managed switches at the network edge where preventing IP/MAC spoofing attacks is required. Engineers can download the TPLINK-IP-SOURCE-GUARD-MIB file directly to load it into their MIB browser.

Specific table/object names were not present in the provided sample, so a concrete polling example is not grounded in real identifiers; based on the module description, an administrator would check per-port IP Source Guard enable status and review the IP/MAC/port binding table to confirm only authorized source addresses are permitted, flagging any port carrying non-matching traffic as a possible spoofing attempt.

Configures IP source guard for port-level security on TP-LINK switches to prevent IP spoofing attacks.
