Direct from the Cisco Wiki, a handy tip which allows you to show the complete configuration of Cisco devices without the breaks or pauses:
1. Type term length 0 in privileged mode to set your terminal to display without any breaks.
2. Type show running-config or show startup-config to show the applicable config. The config will display without any breaks or pauses.
To display the config without lengthy certificate data, use show run brief.This is useful for capturing the complete config for documentation purposes, especially if you do not have access via TFTP or the like.
