KRON is a command scheduler tool. It helps to trasform routine manual actions into automatic ones while administering Cisco network devices.
The following is an example of dropping ISP session on interface Fa0/0 every day at 00:00:
evilttl(config)#kron policy-list IntReset
evilttl(config-kron-policy)#cli clear interface fa0/0
evilttl(config)#kron occurrence ResetTime at 00:00 recurring
evilttl(config-kron-policy)#policy-list IntReset
evilttl(config)#show kron schedule
Another example of KRON functionality is automatic self-backup service provisioning every Sunday at 23:00:
evilttl(config)#kron policy-list Backup
evilttl(config-kron-policy)#cli show run | redirect tftp://172.16.1.10/evilttl.cfg
evilttl(config)#kron occurrence Backup at 23:00 Sun recurring
evilttl(config-kron-policy)#policy-list Backup
evilttl(config)#show kron schedule
