phivCircuitCountAdjDown
Module: DECnet-iv
OID (symbolic): DECnet-iv::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?
Cumulative count of adjacency losses on this circuit, covering causes such as a listener timeout, invalid or unexpected control data, a routing-message checksum error, a mismatched node identity, one-way connectivity, or the adjacency simply going idle. A rising count here is the primary signal that a neighboring node's link keeps dropping rather than staying continuously reachable.
