EEM - Shut/no shut applet targeting specific interface descriptions

[Paccers]

Hi all,

Had a look around previous posts but couldn't find anything specifically for what I'm aiming to do.

I have successfully tested two very basic EEM applets to shut/no shut an interface at specific times. However, this was done by specifying the interface ID in the action cli command set:

event manager applet shutdown_gigport
event timer cron cron-entry "00 22 * * *"
action 10 cli command "enable"
action 20 cli command "config t"
action 30 cli command "interface GigabitEthernet1/0/1"
action 40 cli command "shut"
action 50 cli command "end"
action 60 syslog msg "Interface GigabitEthernet1/0/1 has been shutdown"

event manager applet noshut_gigport
event timer cron cron-entry "00 6 * * *"
action 10 cli command "enable"
action 20 cli command "config t"
action 30 cli command "interface GigabitEthernet1/0/1"
action 40 cli command "no shut"
action 50 cli command "end"
action 60 syslog msg "Interface GigabitEthernet1/0/1 has been restored"

I'm looking to have the applets action against all interfaces where the description contains a specific string e.g. I want to shut/no shut interfaces at 10pm and 6am WHERE interface description contains 'wireless'.

Any assistance with this would be appreciated!

Look at below thread you can use regex your description and shutdown the port:

Thanks for the link!

Here is an example to manage the ports at a given time of day.

event manager applet wireless
 event timer cron cron-entry "0 6,22 * * *"
 action 002 puts "$_event_pub_time"
 action 003 regexp "[a-zA-z]+\s+[0-9]+\s+([0-9]+):" "$_event_pub_time" match hour
 action 004 if $hour eq "06"
 action 005  set action "no shutdown"
 action 006 else
 action 007  set action "shutdown"
 action 008 end
 action 009 puts "$hour and $action"
 action 010 cli command "enable"
 action 020 cli command "config t"
 action 025 cli command "do show run | inc WIRELESS$|^interface"
 action 030 foreach line "$_cli_result" "\n"
 action 040  regexp "interface ([a-zA-Z0-9\/]+)" "$line" match intf
 action 050  regexp "description WIRELESS" "$line"
 action 060  if $_regexp_result eq "1"
 action 070   cli command "interface $intf"
 action 080   cli command "$action"
 action 090  else
 action 100   continue
 action 110  end
 action 120 end

Thanks for the comprehensive reply there Dan!

I did a quick test and noticed that it didn't perform the shutdown action when planned as the time it checks against ('$_event_pub_time' I think) comes out in UTC timezone whereas we are not on UTC time. Switch NTP is correct and I have the following service timestamps configs set:

service timestamps debug datetime msec localtime show-timezone
service timestamps log datetime msec localtime show-timezone

Can I get that clock output to be in the local timezone or do I just need to adjust the cron hour values to match UTC?
