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.

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> DECNET-PHIV-MIB::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> DECNET-PHIV-MIB::phivCircuitCountAdjDown.1
