Description: Manages ZyXEL DHCPv6 client and server configuration for IPv6 address and parameter assignment.

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-MIB?

ZYXEL-DHCPV6-MIB is a ZyXEL proprietary MIB covering the DHCPv6 subtree, managing both DHCPv6 client and server configuration used for assigning IPv6 addresses and network parameters to hosts. Its data is primarily configuration and state-oriented, covering client/server mode settings, prefix delegation, and lease-like assignment tracking for IPv6 clients. In monitoring terms it supports verifying that IPv6 address assignment software is functioning -- for instance confirming a device successfully obtained or is correctly serving IPv6 addresses/prefixes to downstream devices -- rather than tracking physical hardware status. It conceptually aligns with IETF DHCPv6 standards (RFC 3315 and related) even though implemented as a ZyXEL-specific management tree. It is typically deployed on ZyXEL routers/gateways operating in IPv6-enabled networks, either as a DHCPv6 client toward an upstream ISP or as a server/prefix-delegation source for a LAN. Engineers can download the ZYXEL-DHCPV6-MIB file directly to load it into their MIB browser.

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

Monitoring Examples

No object or table names were provided in sample_objects for this module, so specific polling targets cannot be confirmed from the given data. Conceptually, an operator would poll DHCPv6 client or server status objects to confirm whether the device has obtained a valid IPv6 address/prefix from its upstream DHCPv6 server, or whether it is correctly delegating prefixes to LAN clients. Because sample_objects is empty, no invented object names are given here.

OIDs

OID symbolic	OID numeric	Type	Access	Description
INT zyDhcpv6ClientIaType	1.3.6.1.4.1.890.1.15.3.21.1.3.1.2	INTEGER	read-write	Enable/Disable the switch to get a non-temporary IP address from the DHCP server.
INT zyDhcpv6ClientIaTypeRapidCommit	1.3.6.1.4.1.890.1.15.3.21.1.3.1.3	INTEGER	read-write	Enable/Disable the switch to send its DHCPv6 solicit message with a rapid commit option to obtain information from the DHCP server by a rapid two-message exchange. The switch discards any reply message that does not include a rapid commit option. The DHCP server should also support rapid commit option to have it work well.
INT zyDhcpv6ClientIfIndex	1.3.6.1.4.1.890.1.15.3.21.1.3.1.1	INTEGER	not-accessible	DHCPv6 client interface index.
U32 zyDhcpv6ClientInfoRefreshMinimum	1.3.6.1.4.1.890.1.15.3.21.1.3.1.6	Unsigned32	read-write	Sets the time interval (in seconds) at which the switch exchanges other configuration information with a DHCPv6 server again.
ENA zyDhcpv6ClientInfoRestart	1.3.6.1.4.1.890.1.15.3.21.2.1.1.1	EnabledStatus	read-write	Set the switch to send a release message for the assigned IPv6 address to the DHCP server and start DHCP messages exchange again.
ENA zyDhcpv6ClientOptionDnsState	1.3.6.1.4.1.890.1.15.3.21.1.3.1.4	EnabledStatus	read-write	Enable/Disable DHCPv6 client DNS option is means add DNS option to DHCPv6 client requests.
ENA zyDhcpv6ClientOptionDomainListState	1.3.6.1.4.1.890.1.15.3.21.1.3.1.5	EnabledStatus	read-write	Enable/Disable DHCPv6 client Domain-List option is means add domain list information to DHCPv6 client requests.
INT zyDhcpv6MaxNumberOfRelays	1.3.6.1.4.1.890.1.15.3.21.1.1	INTEGER	read-only	The maximum numbers of DHCPv6 relay entry that can be created.
IP zyDhcpv6RelayHelperIpAddress	1.3.6.1.4.1.890.1.15.3.21.1.2.1.2	InetAddress	read-write	Enter the IPv4/IPv6 address of a DHCPv6 server.
IPt zyDhcpv6RelayHelperIpAddressType	1.3.6.1.4.1.890.1.15.3.21.1.2.1.3	InetAddressType	read-write	Enter the type of DHCPv6 relay helper address.
ENA zyDhcpv6RelayOptionIfIdState	1.3.6.1.4.1.890.1.15.3.21.1.2.1.4	EnabledStatus	read-write	Enable/Disable the switch to add interface ID option in DHCPv6 requests from the clients in the specified VLAN before the switch forwards them to a DHCP server.
STR zyDhcpv6RelayOptionRemoteIdData	1.3.6.1.4.1.890.1.15.3.21.1.2.1.5	DisplayString	read-write	Set the switch to add the remote-ID option in the DHCPv6 requests from the clients in the specified VLAN before the switch forwards them to a DHCP server. This also specifies a string (up to 64 printable ASCII characters) to be carried in the remote-ID option. If this field is empty means this option is disabled.
ROW zyDhcpv6RelayRowStatus	1.3.6.1.4.1.890.1.15.3.21.1.2.1.6	RowStatus	read-create	This object allows DHCPv6 relay entries to be created and deleted.
INT zyDhcpv6RelayVid	1.3.6.1.4.1.890.1.15.3.21.1.2.1.1	INTEGER	not-accessible	Enter the VLAN ID to which these DHCPv6 relay settings apply.
