Description: Defines ZyXEL DHCPv6 trusted port configuration for filtering rogue DHCPv6 server messages on access ports.

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 ZYXEL-DHCPV6-TRUST-MIB?

ZYXEL-DHCPV6-TRUST-MIB manages DHCPv6 trusted-port configuration on ZyXEL managed switches, a security feature that designates which ports are allowed to relay DHCPv6 server messages, filtering out rogue DHCPv6 servers on untrusted access ports. It exposes configuration objects marking each port as trusted or untrusted for DHCPv6 server traffic, and typically counters or logs of filtered/blocked messages. Its monitoring value is security-oriented software status: an administrator can confirm the trust configuration matches network design and monitor for rogue DHCPv6 activity being dropped on untrusted ports, indicating a potential misconfigured or malicious device on the network. It builds on the vendor-neutral DHCPv6 (RFC 8415) protocol and complements a switch's Layer 2 security feature set alongside DHCPv6 snooping/guard concepts. It is deployed on ZyXEL managed switches at the network edge to protect against rogue DHCPv6 servers. Network engineers evaluating or troubleshooting this functionality can download the ZYXEL-DHCPV6-TRUST-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ZYXEL-DHCPV6-TRUST-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

  • ZyXEL managed switches

Monitoring Examples

No object names were captured in sample_objects, but consistent with its purpose the module would expose a per-port trust-state table and a counter of DHCPv6 server messages dropped on untrusted ports. An administrator seeing a rising drop counter on an access port would investigate a rogue or misconfigured DHCPv6 server device connected there.

What Can Be Monitored

  • per-port DHCPv6 trust state
  • blocked/dropped rogue DHCPv6 messages
  • trusted port configuration
