What Is Juniper-DNS-MIB?

Juniper-DNS-MIB is a Juniper Networks enterprise MIB for the E-series broadband access router family that manages DNS proxy configuration, including configured DNS server lists and local domain name suffixes offered to subscribers. It exposes objects for enabling the DNS proxy feature, listing configured DNS servers (both IPv4-only and combined IPv4/IPv6 address forms), and local domain name lists with row status for each entry. Its monitoring role is primarily configuration/service status: an administrator verifies juniDnsEnable is set as expected and checks juniDnsServerListTable/juniDnsV4V6ServerListAddress entries to confirm the correct upstream DNS servers are configured and active, catching a misconfigured or removed DNS server that could break subscriber name resolution. It is a self-contained configuration MIB for Juniper's DNS proxy feature without strong cross-MIB dependencies. It is deployed on Juniper E-series broadband edge routers that proxy DNS resolution for downstream subscribers. Network engineers evaluating or troubleshooting this functionality can download the Juniper-DNS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Juniper-DNS-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

An operator would check juniDnsEnable to confirm the DNS proxy feature is active, then walk juniDnsServerListTable/juniDnsServerListEntry (or the dual-stack juniDnsV4V6ServerListAddressType/juniDnsV4V6ServerListAddress) to verify the configured upstream DNS server addresses and their juniDnsServerListRowStatus. An unexpectedly missing or non-active row status on a server entry would explain subscriber DNS resolution failures. juniDnsLocalDomainNameListTable/juniDnsLocalDomainNameListEntry lets the admin confirm the local domain suffixes being appended to subscriber DNS queries are correctly provisioned.

OIDs

OID symbolic	OID numeric	Type	Access	Description
juniDnsMIB	1.3.6.1.4.1.4874.2.2.47			The DNS MIB for the Juniper Networks, Inc. enterprise.
juniDnsObjects	1.3.6.1.4.1.4874.2.2.47.1
juniDnsGeneral	1.3.6.1.4.1.4874.2.2.47.1.1
JUN juniDnsEnable	1.3.6.1.4.1.4874.2.2.47.1.1.1	JuniEnable	read-write	Exerts administrative control to enable/disable DNS capability.
juniDnsServerList	1.3.6.1.4.1.4874.2.2.47.1.2
JUN juniDnsServerListNextIndex	1.3.6.1.4.1.4874.2.2.47.1.2.1	JuniNextServerListIndex	read-only	Coordinate juniDnsServerListIndex value allocation for entries in juniDnsServerListTable. A GET of this object returns the next available index value to be used to create an entry in the associated table; or zero, if no valid index value is available. This object also returns a value of zero when it is the lexicographic successor of a varbind presented in an SNMP GETNEXT or GETBULK request, for which circumstance it is assumed that index allocation is unintended. Successive GETs will typically return different values, thus avoiding collisions among cooperating management clients seeking to create table entries simultaneously.
juniDnsServerListTable	1.3.6.1.4.1.4874.2.2.47.1.2.2		not-accessible	This table contains an entry for each DNS server.
juniDnsServerListEntry	1.3.6.1.4.1.4874.2.2.47.1.2.2.1		not-accessible	Each entry corresponds to an associated DNS server.
SER juniDnsServerListIndex	1.3.6.1.4.1.4874.2.2.47.1.2.2.1.1	ServerListIndex	not-accessible	The index of the DNS server. When creating entries in this table, suitable values for this object are determined by reading juniDnsServerListNextIndex.
IP juniDnsServerListAddress	1.3.6.1.4.1.4874.2.2.47.1.2.2.1.2	IpAddress	read-create	The IP address of the DNS server. This object has been replaced by juniDnsV4V6ServerListAddressType and juniDnsV4V6ServerListAddress.
ROW juniDnsServerListRowStatus	1.3.6.1.4.1.4874.2.2.47.1.2.2.1.3	RowStatus	read-create	Controls creation/deletion of entries in this table according to the RowStatus textual convention, constrained to support the following values only: createAndGo destroy
IPt juniDnsV4V6ServerListAddressType	1.3.6.1.4.1.4874.2.2.47.1.2.2.1.4	InetAddressType	read-create	The type of IP address (IPv4 or IPv6) of the DNS server.
IP juniDnsV4V6ServerListAddress	1.3.6.1.4.1.4874.2.2.47.1.2.2.1.5	InetAddress	read-create	The IP address of the DNS server. Note: Since this object is used to configure the IPv4 or IPv6 address depending on juniDnsV4V6ServerListAddressType value, it is mandatory to provide the IPv4 or IPv6 address by specifying each octet's positional values explicitly. Example: 1. IPv4 -- 4 octets -- 0xFF 0xFF 0xFF 0xFF 2. IPv6 -- 16 octets -- 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF

A GET of this object returns the next available index value to be used to create an entry in the associated table; or zero, if no valid index value is available. This object also returns a value of zero when it is the lexicographic successor of a varbind presented in an SNMP GETNEXT or GETBULK request, for which circumstance it is assumed that index allocation is unintended. Successive GETs will typically return different values, thus avoiding collisions among cooperating management clients seeking to create table entries simultaneously.
