Regular DHCP Binding Output

[hillda01]

Hi

I want to output the dhcp binding information using a krontab every 1 hour but I can't see to work out the krontab schedule for hourly or the krontab won't do an hourly output.

This is the command that I've got and it works but I want it to run every hour

show ip dhcp binding | redirect tftp://IPAddress/_dhcp_binding.txt

Can anyone tell me how I can schedule it every hour or let me know an alternative suggestion as to

Instead why not use EEM Script for this :

Hello

Possibly try this, I haven't tested it but it should run at every minute past the hour on every day of week.
event manager applet DHCP
event timer cron cron-entry "1 1-23 * * 0-6"
action 1.1 cli command "enable"
action 1.2 cli command "show ip dhcp binding | redirect tftp://IPAddress/_dhcp_binding.txt"
action 1.3 cli command "end"

I don't have

event manager applet

or

event timer

It's a Cisco 9300 switch I'm trying to configure it on

Hello

Not sure not tried eem on 9ks before try as i posted it?

My mistake - I think I need to configure / create the applet first in conf t mode

FYI

That cron timer sequence does work as expected , just tested it on IOS

[hillda01]

So is it....?

conf t

event manager applet DHCP
event timer cron cron-entry "1 1-23 * * 0-6"
action 1.1 cli command "enable"
action 1.2 cli command "show ip dhcp binding | redirect tftp://IPAddress/_dhcp_binding.txt"
action 1.3 cli command "end"

yes here is IOX XE reference in case if you required.
