Statistics Commands

Each LANIC card contains counters for accumulating various statistics of individual card events. In addition, Node Manager software contains a counter for the occurrence of orphan packets received on the system. These •statistics" may be read or cleared from both local or remote nodes. They are summarized in Table 5"11.

Note

The LANIC Self"Test Command, TC, will also clear statistics counters main" tained by the LANIC card. It will not clear the statistic counter maintained by the Node Manager software.

The maximum value of each statistics counter is shown in Table 5"11. When a counter's maximum value is reached, that value is maintained until cleared; it does not automatically roll"over to zero.

The statistics gathered can provide insight into the efficient operation of the node or network. However, interpretation of the statistics provided is not often trivial. Different conclusions may be deduced from different combinations of statistics.

The ability to interpret the statistics will improve with experience.There are two Statistics Commands; they are discussed in the pages that follow:DRead Link Statistics Counters, RSDZero Link Statistics Counters, ZS
