EEM Script for displaying multiple line from a single command

[StrugglingEngineer]

Hello,

I am currently working on a eem script and I am struggling to display a script output line by line on a syslog.

The command is show mab all sum and the result is usually like this :

Interface Client Mac Authen Status

Gi1/0/1 aaaa.bbbb.cccc SUCCESS

Tw2/0/2 cccc.dddd.eeee FAILED

Tw3/0/3 rrrr.dddd.aaaa SUCCESS

etc etc ...

Here is my current script :

event manager applet timer-display-mab-int

event timer watchdog time 10

action 1.1 cli command "enable"

action 1.2 cli command "show mab all sum"

action 1.3 foreach loop $_cli_result "\n"

action 1.4 regexp "(Gi([0-9/]+)|Tw([0-9/]+)) "$_cli_result" match ifname

action 1.5 syslog msg "Interface name is $ifname"

action 1.6 end

The goal is to display a syslog with each interface number (and more later on)

For example syslog would display :

Interface name is Gi1/0/1

Interface name is Tw2/0/2

Interface name is Tw3/0/3

Can anyone help me in any way ?

Let me know if I wasn't clear enough !

Thanks in advance,

Hi friend'

I think you can use aaa account and send syslog to server

I will check this point

Hey, thank you for answering !

However I am trying to do that so I can later replace the syslog message results with commands, such as clear authentifications sessions etc ...

So sending the results into a syslog server or else is not gonna help :(.

I do not have mab running so here is an example with another command to filter out only GigabitEthernet and Loopback interfaces.   I believe your regexp statement needs to be updated and also add in the $_regexp_result eq 1 command so it does not throw an error when iterating over lines that do not match.

event manager applet test
 event none
 action 010 cli command "enable"
 action 020 cli command "show ip int brief"
 action 040 foreach loop "$_cli_result" "\n"
 action 050  regexp "(^[GL][a-zE0-9\/\.]+)" "$loop" match ifname
 action 055  if $_regexp_result eq "1"
 action 060   syslog msg "Interface name is $ifname"
 action 100  end
 action 110 end
INET#event manager run test
INET#

Thank you very much for your help ! I tweaked it a bit to match my needs , but adding the second loop (if statement + rege result variable) did the job !

You are the GOAT, please keep that in mind.

Have a great day !
