Data structure that can be access within an EEM applet

[Comm4nd0]

Hi, is it possible to have some kind of data structure that's accessible from an EEM applet?

So what id like to do is this. when the EEM applet is called and run, i'd like it to find the switches serial number and depending on the serial number apply a specific config. something like this

event manager applet update_confg
event none
action 1.0 cli command "enable"
action 2.0 cli command "show version | include system serial number"
action 3.0 cli command regex "[A-Z0-9]{11}" "$_cli_result" serial
action 4.0 if $serail eq "123456789"
action 4.1 cli command "run config1.sh"
action 5.0 elif $serail eq "987654321"
action 5.1 cli command "run config2.sh"
action 6.0 elif $serail eq "123123123"
action 6.1 cli command "run config3.sh"
action 7.0 end
!
do event manager run update_config

so instead of having lots of IF statements it would be better if it simply did a lookup of some kind. i.e. return me a string(config file name) where serial number == $serial. This would prevent having lots of IF statements.

Any idea how i might do this?

Hello,

You would have to play with it but if you had a file that had the SNs and the corresponding filenames, you could use that to do the lookup. The syntax below might not be exact but hopefully it helps:

Contents of flash:SNtoConfigFile.txt

Serial1:Config1.txt

Serial2:Config2.txt

Serial3:Config3.txt

Serial4:Config3.txt

event manager applet configlookup
event none
action 1.0 cli command "show version | include system serial number"
action 1.1 cli command regex "[A-Z0-9]{11}" "$_cli_result" serial
action 1.2 set snumber $serial
action 1.3 cli command "more flash:SNtoConfigFile.txt | inc $snumber"
action 1.4 cli command regex "Config\d.txt" "$_cli_result" file
action 1.5 set config $file
action 1.6 cli command "copy flash:$config start"

Hope that helps!

Ah, so do you think it would be possible to do something more like this?

more serial_data.cfg

config1.txt: 123456789, 987654321, 147258369

config2.txt: 784512235, 326598875, 786453159

event manager applet configlookup
event none
action 1.0 cli command "show version | include system serial number"
action 1.1 cli command regex "[A-Z0-9]{11}" "$_cli_result" serial
action 1.2 set snumber $serial <--- not sure why you created another variable?
action 1.3 cli command "copy ftp://192.168.0.128/serial_data.cfg flash:"
action 1.4 cli command "more flash:serial_data.cfg | inc $snumber"
action 1.5 cli command regex "^config\d.txt:" "$_cli_result" file
action 1.5 set config $file <-- and again? but i'll roll with it.
action 1.6 cli command "copy ftp://192.168.0.128/$config flash:$config start" <-- not sure if this will work?
action 1.7 end

What do you think? feasible?

Looks about right. You might also need to set your default FTP username/pass if you have one ahead of time. You will need two things though as the copy command asks for more information and will cause your script to get stuck:

event manager applet configlookup
event none maxrun 1000 <-----EEM will timeout in 20 seconds by default. This might run a little longer.
action 1.0 cli command "show version | include system serial number"
action 1.1 cli command regex "[A-Z0-9]{11}" "$_cli_result" serial
action 1.2 set snumber $serial <--- Not required. Force of habit from other scripts
action 1.3 cli command "conf t"
action 1.4 cli command "file prompt quiet" <----You have to do this or you will get stuck on the copy command
action 1.5 cli command "end"
action 1.6 cli command "copy ftp://192.168.0.128/serial_data.cfg flash:"
action 1.7 cli command "more flash:serial_data.cfg | inc $snumber"
action 1.8 cli command regex "^config\d.txt:" "$_cli_result" file
action 1.9 set config $file 
action 2.0 cli command "copy ftp://192.168.0.128/$config flash:$config start" <---Should be fine.
action 2.1 end

Hope that helps!

thanks so much for your help. Here is the current working applet i'm using.

event manager applet configlookup
event none maxrun 1000
action 1.0 cli command "enable"
action 2.0 cli command "show version | include System Serial Number"
action 2.1 regexp "[A-Z0-9][A-Z0-9][A-Z0-9][A-Z0-9][A-Z0-9][A-Z0-9][A-Z0-9][A-Z0-9][A-Z0-9][A-Z0-9][A-Z0-9]" "$_cli_result" serial
action 3.0 cli command "conf t"
action 4.0 cli command "file prompt quiet"
action 5.0 cli command "end"
action 6.0 cli command "copy ftp://192.168.0.128/serial_data.yml flash:"
action 6.1 cli command "more flash:serial_data.yml | inc $serial"
action 7.8 regexp "^[A-Z0-9]+.txt" "$_cli_result" file
action 8.0 cli command "copy ftp://192.168.0.128/$file nvram:startup-config"
!
exit
do event manager run configlookup
