show service module vs sh controllers

What is the difference between the show service module command output versus th show controllers output? Is one better or more accurate than the other? Are these layer one or two statistics? Thanks.


Re: show service module vs sh controllers

It displays layer 2 statistics. To display the performance report for an integrated CSU/DSU, use the show service-module serial command in privileged EXEC mode. show service-module serial number [performance-statistics [interval-range]]

Displays the CSU/DSU performance statistics for the past 24 hours. This keyword applies only to the fractional T1/T1 module.

To display serial controller statistics. the show controllers serial command also displays configuration information such as the framing, clock source, bandwidth limit, whether scrambling is enabled, the national bit, the international bits, and DSU mode configured on the interface. Also displayed are the performance statistics for the current interval and last 15-minute interval and whether any alarms exist.
