Description: Defines DEC DECnet Phase IV network protocol management objects per RFC 1289.

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 RFC1289-phivMIB?

RFC1289-phivMIB is a vendor-neutral, standards-based IETF MIB defining management objects for DECnet Phase IV, Digital Equipment Corporation's proprietary network protocol suite, as specified in RFC 1289. It exposes DECnet-specific configuration and operational data such as node addressing, circuit status, and routing/adjacency information relevant to Phase IV networks. Its monitoring role is chiefly around software/protocol status: node reachability, circuit up/down state, and routing adjacency health on DECnet nodes rather than physical hardware sensors. It stands somewhat independently of TCP/IP-centric MIBs like MIB-II, being tailored to the separate DECnet protocol stack, though it follows the same SMI conventions for structuring. It would be deployed in legacy VAX/VMS or DECnet-based environments, largely of historical interest today as DECnet Phase IV networks have been phased out. Engineers implementing or auditing this functionality typically reference the RFC1289-phivMIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in RFC1289-phivMIB. 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

vendor-neutral, standards-based MIB, not tied to a specific manufacturer
legacy DECnet Phase IV network nodes (historically DEC VAX/VMS systems)

Monitoring Examples

An administrator would poll DECnet node and circuit status objects to confirm a node is reachable and its circuits are operational, watching for a circuit transitioning to a down or off state. Persistent circuit-down conditions or routing adjacency loss would indicate a failed DECnet link between nodes in the network.

What Can Be Monitored

DECnet node status
circuit operational state
routing/adjacency status
node reachability

The values for clock-mode are: INTERNAL For software controllable loopback use of the clock. On those devices that can support this mode, it causes the device to supply a clock signal such that a transmitted messages can be looped back from outside the device. This may require manual intervention other than the setting of this parameter value. For example, the operator may have to connect a loopback plug in place of the normal line.

INT phivRouteBuffSize	1.3.6.1.2.1.18.5.2	INTEGER	read-write	This parameter value determines the maximum size of a Routing message. It therefore determines the maximum size message that can be forwarded. This size includes protocol overhead down to and including the End Communication layer, plus a constant value of 6. (This value of 6 is included to provide compatibility with the parameter definition in Phase III, which included the Routing overhead.) It does not include Routing or Data link overhead (except for the constant value of 6). There is one buffer size for all circuits. NOTE: The BUFFER SIZE defines the maximum size messages that the Routing layer can forward. The SEGMENT BUFFER SIZE (defined below) defines the maximum size messages that the End Communication layer can transmit or receive. The SEGMENT BUFFER SIZE is always less than or equal to the BUFFER SIZE. Normally the two parameters will be equal. They may be different to allow the network manager to alter buffer sizes on all nodes without interruption of service. They both include an extra 6 bytes for compatibility with Phase III.

INT phivRouteMaxCost	1.3.6.1.2.1.18.5.9	INTEGER	read-write	This value represents the maximum total path cost allowed from the executor to any node within an area. The path cost is the sum of the circuit costs along a path between two nodes. This parameter defines the point where the executor node's Routing routing decision algorithm declares another node unreachable because the cost of the least costly path to the other node is excessive. For correct operation, this parameter must not be less than the maximum path cost of the network.
INT phivRouteMaxHops	1.3.6.1.2.1.18.5.10	INTEGER	read-write	This value represents the maximum number of routing hops allowable from the executor to any other reachable node within an area. (A hop is the logical distance over a circuit between two adjacent nodes.) This parameter defines the point where the executor node's Routing routing decision algorithm declares another node unreachable because the length of the shortest path between the two nodes is too long. For correct operation, this parameter must not be less than the network diameter. (The network diameter is the reachability distance between the two nodes of the network having the greatest reachability distance, where reachability distance is the length the shortest path between a given pair of nodes.)
INT phivRouteMaxVisits	1.3.6.1.2.1.18.5.11	INTEGER	read-write	This value represents the maximum number of nodes a message coming into the executor node can have visited. If the message is not for this node and the MAXIMUM VISITS number is exceeded, the message is discarded. The MAXIMUM VISITS parameter defines the point where the packet lifetime control algorithm discards a packet that has traversed too many nodes. For correct operation, this parameter must not be less than the maximum path length of the network. (The maximum path length is the routing distance between the two nodes of the network having the greatest routing distance, where routing distance is the length of the least costly path between a given pair of nodes.)
INT phivRouteRoutingTimer	1.3.6.1.2.1.18.5.12	INTEGER	read-write	This value determines the maximum time in seconds allowed between Routing updates on non-Ethernet circuits. When this timer expires before a routing update occurs, a routing update is forced.

INT phivRouteType	1.3.6.1.2.1.18.5.14	INTEGER	read-only	This parameter indicates the type of the executor node. The node-type is one of the following: routing-III nonrouting-III routing-IV ronrouting-IV area A routing node has full routing capability. A nonrouting node contains a subset of the Routing routing modules. The III and IV indicate the DNA phase of the node. Nonrouting nodes can deliver and receive packets to and from any node, but cannot route packets from other nodes through to other nodes. An area node routes between areas. Refer to the Routing specification for details. For adjacent nodes, this is a read-only parameter that indicates the type of the reachable adjacent node. NOTE: The ROUTING-III and NONROUTING-III values are incremented by one compared to the standard DECnet values in order to maintain compliance with RFC 1155)
INT phivSessionInTimer	1.3.6.1.2.1.18.3.2	INTEGER	read-write	This value represents the maximum duration between the time a connect is received for a process at the executor node and the time that process accepts or rejects it. If the connect is not accepted or rejected by the user within the number of seconds specified, Session Control rejects it for the user. A 0 indicates no timer is running.
INT phivSessionOutTimer	1.3.6.1.2.1.18.3.3	INTEGER	read-write	This value represents the duration between the time the executor requests a connect and the time that connect is acknowledged by the destination node. If the connect is not acknowledged within the number of seconds specified, Session Control returns an error. A 0 indicates no timer is running.
STR phivSessionSystemName	1.3.6.1.2.1.18.3.1	DisplayString	read-only	Name to be associated with the node identification. Only one name can be assigned to a node address or a circuit identification. No name should be used more than once in a DECnet network. Node-name is one to six upper case alphanumeric characters with at least one alpha character. A length of 0 indicates no name.
