Cisco Cisco IOS Software Release 12.4(15)T

The Command Scheduler (KRON) Policy for System Startup features enables support for Command 
Scheduler upon system startup. 

Command Scheduler allows customers to schedule fully-qualified EXEC mode CLI commands to run 
once, at specified intervals, at specified calendar dates and times, or upon system startup. Originally 
designed to work with CNS commands, Command Scheduler has a broader application. Using the CNS 
image agent feature, remote routers residing outside a firewall or using Network Address Translation 
(NAT) addresses can use Command Scheduler to launch CLI at intervals to update the image running in 
the router.

Command Scheduler has two basic processes. A policy list is configured containing lines of 
fully-qualified EXEC CLI commands to be run at the same time or interval. One or more policy lists are 
then scheduled to run after a specified interval of time, at a specified calendar date and time, or upon 
system startup. Each scheduled occurrence can be set to run once only or on a recurring basis.

Configuration information is included in the “Configuring Cisco Networking Services” module of the 
Cisco IOS Network Management Configuration Guide, Release 12.4T,
