phivAdjNodeState
Module: DECNET-PHIV-MIB
OID (symbolic): DECNET-PHIV-MIB::phivAdjNodeState
OID (numeric): 1.3.6.1.2.1.18.11.2.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This value indicates the state of a router adjacency. On adjacencies over a circuit of type (phivCircuitCommonType) Ethernet, CI, or FDDI, with an adjacent node of type (phivAdjNodeType) ROUTING IV or AREA, this variable is the state of the Ethernet Initialization Layer for this adjacency, and can have values INITIALIZING or UP. (See Section 9.1.1 of DECnet Phase IV Routing Layer Functional Specification.)
On adjacencies over a circuit of type (phivCircuitCommonType) Ethernet, CI, or FDDI, with an adjacent node of type (phivAdjNodeType) NONROUTING IV, this variable will always take on the value UP.
On adjacencies over a circuit of type (phivCircuitCommonType) DDCMP POINT, DDCMP CONTROL, DDCMP TRIBUTARY, DDCMP DMC, or X.25, this variable is the state of the Routing Layer Initialization Circuit State. (See section 7.3, ibid.) It can have values between RUN and HALT.
On adjacencies over a circuit of type (phivCircuitCommonType) OTHER, this variable may be used in a manner consistent with the Initialization Layer used on that circuit.
What is phivAdjNodeState?
Read-only state of this router adjacency; on Ethernet/CI/FDDI circuits it reflects the Ethernet initialization layer (INITIALIZING or UP), while on DDCMP/X.25 circuits it reflects the routing-layer initialization circuit state cycling from RUN down to HALT. The primary field an admin checks to confirm whether a given neighbor relationship is actually up.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.18.11.2.1.7 snmpwalk -v2c -c public <target> DECNET-PHIV-MIB::phivAdjNodeState
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.18.11.2.1.7.1 snmpget -v2c -c public <target> DECNET-PHIV-MIB::phivAdjNodeState.1
