Shutdown a port at specific time in Nexus Switch 9k

[jair6a]

I have searching something useful to do this, but I haven´t funded something useful. I wanted to use "event timer feature" (with EEM) like IOS but seems like it does not exist in NXOS versions. Could you help me with some ideas?

Version 10.1(1) Nexus

93108TC-EX

Thank you!

Hi @jair6a 

I see the option to use timer with EEM available for both N7k and N9K:

 event timer {absolute time time name name | countdown time time name name | cron cronentry string | tag tag | watchdog time time name name} 

If the feature is missing you probably need to upgrade your NXOS version.

Here is the config guide:

Take care,

Sergiu

Thank you for your reply. In fact, I found the configuration guide for the specific version (10.1):

Cisco Nexus 9000 Series NX-OS System Management Configuration Guide, Release 10.1(x) - Configuring the Embedded Event Manager [Cisco Nexus 9000 Series Switches] - Cisco

and I saw the option in the guide as you mentioned before, but in the cli of my switches it isn´t.

Could you write it as a Python script and use the nx-os scheduler?

An example is shown at the end of this page:

NX-OS Programmability Guide

I tried this, but it didn't run. Sorry it's not much help, but it might just point you in the right direction:

event manager applet SHUTPORTs
action 0001 cli command "enable"
action 0002 cli command "configure terminal"
action 0003 cli command "interface Eth1/10"
action 0004 cli command "descr EEM-Script" <- change to shutdown
action 0005 cli command "end"
action 0006 syslog msg SHUTPORTs EEM has executed
exit
!
feature scheduler
scheduler job name JOB-SHUTPORTs
 event manager run SHUTPORTs
exit
scheduler schedule name SCH-SHUTPORTs
 job name JOB-SHUTPORTs
 time start 2022:09:13:22:00
exit

show scheduler schedule

[jair6a]

You´re right. I tried with scheduler feature and it´s so easy!

I tried next:

scheduler job name SHUTPORT
configure
interface loopback0
shutdown

end-job

scheduler schedule name WEEKENDs
job name SHUTPORT
time start 2022:09:13:18:26 repeat 0:24:0

And the result was the following:

N9k# show clock
Time source is NTP
18:24:33.693 UTC Tue Sep 13 2022

Thank you for your help!

Thanks for posting back. Good to see that all the config can be handled directly under the scheduler job section without needing the EEM applet.
