Using KRON to do automatic backups. Having an issue

I'm trying to use Kron to backup the config on some of my switches automatically. When the schedule runs, it just writes a 0KB file and the process just sits there.

Here's my config:

show run | begin kron

kron policy-list Backup

cli show run | redirect tftp://

kron occurance Backup at 12:30 Wed recurring           

When I do a show proccesses cpu I get this:

PID Runtime(ms)   Invoked      uSecs   5Sec   1Min   5Min TTY Process

  292           0         6          0  0.00%  0.00%  0.00%   0 Kron Process


#show processes memory 292
Process ID: 292
Process Name: Kron Process
Total Memory Held: 25072 bytes

Processor memory Holding = 25072 bytes
pc = 0x01EECD7C, size =     24044, count =    1
pc = 0x0135A880, size =       700, count =    1
pc = 0x0135D398, size =       200, count =    1
pc = 0x01EEE2FC, size =       128, count =    1

I/O memory Holding = 0 bytes

Driver text memory Holding = 0 bytes

My TFTP server that's running shows this in the logs:

Connection received from on port 61403 [21/11 13:38:08.401]

If I run this command manually from the switch, it works. It takes a minute, but it works.

show run | redirect tftp://

Using KRON to do automatic backups. Having an issue

What is the HW platform and SW version ?

Would it be possible to temporarily change the KRON job time, run 'debug kron all' when the job has started and present the outcome ?




Can you please help me with the command to get output for multiple show commands in a single text file like show vlan brief, show interface trunk, show ip eigrp neighbor and so on. Thanks.
