Hi Jan,

Kron [Command Schedular] feature is not supported on switches.

Check the feature Navigator -

"kron policy-list list-name" Command was introduced in 12.3.1 IOS -

You can use EEM insteak of Kron policy to achieve the same. Please have your 3750 to be upgraded to the latest IOS and then download the EEM script for doing the automatic backup of the config.

Link for downloading the EEM Script.

HTH,Please rate if it does.

Hi All,

Kron is supported in fixed units.  I just did a recreation in 3560, 3750 and 2960 running 12.2(50) and it worked by creating a back up of the show run in a tftp server.

Cisco Feature Navigator mentions this is not supported but it worked for me.  Be clear it mentions it does not support interactive commands; however, I am currently testing that.

SW3560#show clo

15:22:32.881 UTC Tue Jan 15 2013

SW3560#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

SW3560(config)#kron policy-li

SW3560(config)#kron policy-list CONFIGBACKUP

SW3560(config-kron-policy)#cli show run | redirect


SW3560(config-kron-policy)#no cli show run | redirect

SW3560(config-kron-policy)#cli show run | redirect tftp://



SW3560(config)#kron oc

SW3560(config)#kron occurrence CONFIGBACKUP a

SW3560(config)#kron occurrence CONFIGBACKUP at 15:29 ?

  <1-31>     Day of month

  DAY        Day of Week eg mon, tue, etc

  MONTH      Month of year eg jan, feb, etc

  oneshot    Schedule kron occurrence exactly once

  recurring  Schedule kron occurrence repeatedly

SW3560(config)#kron occurrence CONFIGBACKUP at 15:29 one

SW3560(config)#kron occurrence CONFIGBACKUP at 15:29 oneshot ?


SW3560(config)#kron occurrence CONFIGBACKUP at 15:29 oneshot


SW3560(config-kron-occurrence)#policy-list CONFIGBACKUP




Jan 15 15:26:52.928: %SYS-5-CONFIG_I: Configured from console by console

SW3560#show kron sched

Kron Occurrence Schedule

CONFIGBACKUP inactive, will run once in 0 days 00:01:55 at 15:29 on


I hope that helps for you.
