logging neighbor-adjacency

Syntax

logging neighbor-adjacency [ detail ]

Description

Used in the ospf3 context to enable logging of standard or detailed adjacency changes. In the default configuration, logs OSPFv3 neighbor changes into or out of the full adjacency state.

Options

detail

Generates event log messages for all OSPFv3 neighbor adjacency state changes.

no logging neighbor-adjacency

Disables logging neighbor adjacency on the routing switch.

no logging neighbor-adjacency detail

Cancels detailed neighbor adjacency change logging and returns the routing switch to logging only neighbor changes into our out of full adjacency.

Default: Standard full adjacency changes logging enabled.

The neighbor-adjacency event log messages are described in the latest Event Log Reference Guide for your routing switch. In the event log output, neighbors are identified by router ID.

Example output

This example shows the neighbor-adjacency change logging using show log -r OSPF3 command.
