Configuration Management; Diagnostics; Serviceability; Tracing / Logging - Motorola RFS7000 Series System Reference Manual

1.2.1.3 Configuration Management

The system supports redundant storage of configuration files to protect against corruption during a write
operation and ensures (at any given time) a valid configuration file exists. If a configuration file has failed to
completely execute, it is rolled back and the pre-write file is used.
Text Based Configuration
The configuration is stored in a human readable format (a set of CLI commands).

1.2.1.4 Diagnostics

The following switch diagnostics are available:
1. In-service diagnostics – In-service diagnostics provide a range of automatic health monitoring
features ensuring both the system hardware and software are in working order. The in-service-
diagnostics continuously monitor any available physical characteristics (as detailed below) and
issues log messages when either warning or error thresholds are reached. There are three types of
in-service diagnostics:
• Hardware – Ethernet ports, chip failures, system temperature via the temperature sensors
provided by the hardware, etc.
• Software – CPU load, memory usage, etc.
• Environmental – CPU and air temperature, fans speed, etc.
2. Out-of-service diagnostics – Out-of-service diagnostics are a set of intrusive tests run from the user
interface. Out-of-service diagnostics cannot be run while the unit is in operation. The intrusive tests
include:
• Ethernet loopback tests
• RAM tests, Real Time Clock tests, etc.
3. Manufacturing diagnostics – Manufacturing diagnostics are a set of diagnostics used by
manufacturing to inspect the quality of the hardware.

1.2.1.5 Serviceability

A special set of service CLI commands are available to provide additional troubleshooting capabilities for
service personnel (for example, check the time critical processes were started), access to Linux services, panic
logs, etc. Only authorized users or service personnel are provided access to the service CLI.
A built-in packet sniffer allows service personnel to capture incoming and outgoing packets in a buffer.
The switch also maintains various statistics for RF activity, Ethernet ports etc. RF statistics include roaming
stats, packet counters, octets tx/rx, signal, noise SNR, retry, and information for each MU.

1.2.1.6 Tracing / Logging

Log messages are well-defined and documented system messages with various destinations. They are
numbered and referenced by ID. Each severity level group can be configured separately to go to either the
serial console, telnet interface, log file or remote syslog server.
Trace messages are more free-form and are used mainly by support personnel for tracking problems. They are
enabled or disabled using the switch CLI. Trace messages can go to a log file or the serial console.
Log and trace messages are in the same log file, so chronological order is preserved. Log and trace messages
from different processes are similarly interleaved in the same file for the same reason.
