Appendix H Operating Statistics
The CCU and EUM provide a comprehensive set of operating statistics for each of the
following:
• Ethernet Port
• Radio Driver
• MAC Interface
• Routing/Bridging Protocol
• Network Interface
• System Load (Radio Meter)
These statistics can be used as a diagnostic and troubleshooting tool when system
performance is being impaired by interference, radio link degradation, network problems,
atypical end-user applications, capacity issues, and so on.
All of these statistics are available through the command-line interface. Most of the statistics
are also available in the CCU and EUM MIBs, if you want to monitor the LMS4000 900 MHz
radio network from an SNMP manager.
CAUTION: Each CCU and EUM statistic is a maximum 32-bit
number (maximum 4,294,967,296). If a statistics counter exceeds
its maximum value, the counter resets to zero and begins again.
When this occurs, you must either take the rollover into account, or
reset the statistics to re-synchronize the counters. To reset
statistics, type stats clear at the command prompt and press Enter.
As a result of the above, the system uptime rolls over about every 8 days. By checking the
system log file, you can calculate the actual up time, after the unit has been up for more than 8
days.
