phivCircuitCountAdjDown
Module: RFC1289-phivMIB
OID (symbolic): RFC1289-phivMIB::phivCircuitCountAdjDown
OID (numeric): 1.3.6.1.2.1.18.6.2.1.11
Node type: OBJECT-TYPE
Type: PhivCounter
Access: read-only
Description: This counter indicates the number of adjacency losses that result from any of the following: Node listener timeout Invalid data received at node listener Unexpected control (initialization or verification) message received Routing message received with a checksum error Node identification from a routing message or a Hello message that is not the one expected Hello message received indicating that connectivity became one-way Adjacency idled.
What is phivCircuitCountAdjDown?
This counter tallies adjacency losses on this circuit from any cause: a listener timeout, invalid data, an unexpected control message, a routing-message checksum error, an unexpected node ID in a Hello/routing message, one-way connectivity detected via Hello, or the adjacency simply idling out. Admins use it as the top-level indicator that a neighbor relationship on this circuit is unstable, then dig into the specific cause via other counters.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.18.6.2.1.11 snmpwalk -v2c -c public <target> RFC1289-phivMIB::phivCircuitCountAdjDown
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.18.6.2.1.11.1 snmpget -v2c -c public <target> RFC1289-phivMIB::phivCircuitCountAdjDown.1
