Command History
Usage Guidelines The show parser statistics command displays two sets of data:
• The number of commands in the configuration file that was last copied into the running
configuration, and the time it took for the system to parse them (a configuration file can be loaded
into the running configuration at system startup, or by issuing commands such as the copy source
running-config command).
• The status of the Parser Cache feature (enabled or disabled) and the number of command matches
(indicated by hits/misses) since the system was started or since the parser cache was cleared.
The Parser Cache feature optimizes the parsing (translation and execution) of Cisco IOS software
configuration command lines by remembering how to parse recently encountered command lines,
decreasing the time required to process large configuration files.
Examples The following example shows sample output from the show parser statistics command:
Router# show parser statistics
Last configuration file parsed:Number of Commands:1484, Time:1272 ms
Parser cache:disabled, 0 hits, 2 misses
In this example, the Parser Cache feature is disabled, but shows the hit/miss statistics for the two
commands issued while the parser cache was last enabled.
Table 118 describes the key output fields.
