phivLineSubstate

Module: RFC1289-phivMIB

OID (symbolic): RFC1289-phivMIB::phivLineSubstate

OID (numeric): 1.3.6.1.2.1.18.12.1.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This value represents the line's read-only Network Management substate. NOTE that these values are incremented by one compared to the standard DECnet values.

What is phivLineSubstate?

This read-only value reports the line's detailed Network Management substate (e.g. starting, looping, loading, dumping, triggering, synchronizing, failed, running), giving finer status than phivLineState alone. Admins check it when a line is stuck transitioning, to see exactly which phase it's in.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.18.12.1.1.4
snmpwalk -v2c -c public <target> RFC1289-phivMIB::phivLineSubstate

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.18.12.1.1.4.1
snmpget -v2c -c public <target> RFC1289-phivMIB::phivLineSubstate.1

Start monitoring DECnet Phase IV network nodes with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the RFC1289-phivMIB::phivLineSubstate OID value, configure state conditions and alerts, and monitor any DECnet Phase IV network nodes from a single console.
