Procedure 5-5: Log configuration and viewing

- Overview

This section describes the commands used to configure system logging, and to view logs and logging settings.

  • Buffered Log Configuration — Enables logging to an in-memory log that keeps up to 128 logs.

  • Command Logger Configuration — Enables the CLI command logging feature. This enables the system to log all CLI commands issued on it.

  • Console Log Configuration — Enables logging to the console.

See equivalent CLI commands in Logging commands under Utility commands in the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Command Line Interface Guide.
