Shut and No Shut Router Interface at Midnight

davidhuynh5 · ‎04-19-2010

I have a need to shutdown, wait 30 seconds and issue a no shutdown on a router interface daily at 12am. Is there something that I can automate using Cisco IOS. Please keep in mind that I have no programing or scripting experience. Thanks in advance.

conf t

!

interface s6/1/1

shutdown (wait 30 seconds)

no shutdown

Hi,

If your IOS support, you can use EEM to do that.

An example of shutdown interface fa0/0 @ 12:00 and bring it back @ 12:01

event manager applet TEST
event timer cron name TEST cron-entry "0 12 * * *"
action 1 cli command "enable"
action 2 cli command "configure terminal"
action 3 cli command "interface fa0/0"
action 4 cli command "shutdown"
event manager applet TEST1
event timer cron name TEST1 cron-entry "1 12 * * *"
action 1 cli command "enable"
action 2 cli command "configure terminal"
action 3 cli command "interface fa0/0"
action 4 cli command "no shutdown"

HTH,

Lei Tian

Lei,

Thank you. That was very helpful. I have two questions:

1. I'm trying to interpet this line "event timer cron name TEST cron-entry "0 12 * * *" but I don't understand how you got it?

2. Is there a "Dummies Guide to EEM" that you can point me in the right direction? I want to learn how to fish.

Hi,

Cron is the UNIX scheduler, just search on google you will find the syntax and many examples.

For EEM configuration examples, you can search on cisco.com . Here is one of the configuration example:
