Description: Manages TP-Link switch DHCPv6 snooping trusted port assignment and binding table security.
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 TPLINK-DHCP6SNOOPING-MIB?
TPLINK-DHCP6SNOOPING-MIB is a TP-Link private enterprise MIB for configuring DHCPv6 snooping security on its managed switches, letting an administrator designate which ports are trusted for DHCPv6 server traffic and manage the resulting binding table that maps client IPv6 addresses/prefixes to ports and MAC addresses. It is fundamentally a security-configuration and state MIB: it exposes trusted-port assignment and the current snooping binding entries. Its monitoring value lies in confirming the software security status of the switch -- verifying that only intended uplink ports are trusted for DHCPv6 server responses and that the binding table reflects legitimate client leases, which helps catch rogue DHCPv6 servers or spoofed bindings. It builds on standard DHCP-snooping concepts analogous to IPv4 DHCP snooping MIBs but is scoped to IPv6. It is deployed on TP-Link managed/smart switches in networks running dual-stack or IPv6 client access where DHCPv6 spoofing protection is needed, and TPLINK-DHCP6SNOOPING-MIB SNMP monitoring confirms trusted-port and binding-table state stays correct over time.
IPNetwork Monitor allows you to monitor SNMP objects defined in TPLINK-DHCP6SNOOPING-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
- TP-Link managed/smart switches
Monitoring Examples
No specific object names were provided (sample_objects is empty), but consistent with its description an administrator would check which ports are marked as DHCPv6-snooping trusted and review the binding table for expected client IPv6-address-to-MAC-and-port mappings; an unexpected untrusted port suddenly showing DHCPv6 server traffic being blocked, or a binding table entry for an unknown MAC address, would indicate an attempted rogue-DHCPv6 or spoofing attack.
What Can Be Monitored
- DHCPv6 snooping trusted port assignment
- DHCPv6 binding table entries
- client IPv6-to-MAC-to-port bindings
