Summary:
For my own rerence and your delectation, I’m going to talk about the Cisco IOS “show history” command use and defaults, with a brief comparison to Unix-type “history” plus grep. Following that, I’ll discuss changing the history buffer size for a single session, writing the buffer size change to config, and how to display the currently configured history buffer size. Commands used:
show historyterminal history size 50(config-line)#history size 50show terminal
