EEM Applet -- Can you set an Env Var from an Applet?

The 900MhzTX Environment Variable is not getting set.  I'm trying to constantly display the radio data rates in the Sho-Run.  After this works I'll add for the RX and for the other 3 radios.

It runs successfully but doesn't set the Env Var.


event manager applet Radio-Reader

event timer watchdog time 10

action 010 cli command "enable"

action 020 cli command "ssh -l ubnt 192.168.2.11" pattern "assword:"

action 030 cli command "fly2the*" pattern "#"

action 040 cli command "mca-status" pattern "#"

action 050 regexp "wlanTxRate=([0-9\.]+)" $_cli_result

action 060 set 900MhzTX $_cli_result

action 070 cli command "config t" pattern "#"

action 080 cli command "event manager environment 900MhzTX $900MhzTX" pattern "#"

action 090 cli command "exit" pattern "#"

action 100 cli command "exit" pattern "#"

Thanks,

Tim

This looks wrong.  Perhaps you mean:

action 050 regexp "wlanTxRate=([0-9\.]+)" $_cli_result match txrate

action 060 set 900MhzTX $txrate

! Here you need to disconnect from the radio before you can configure anything on the router

action XXX cli command "config t"

...

Thanks!  I'm zeroing in on the solution!

Is the "match txrate" part of the command --or a note by you?

Part of the command.

Sorry, I see the txrate is the var.

The Applet works but gets an error after successfully working:

EEM Applet -- Can you set an Env Var from an Applet?

What error?  The only issue I see is that after you disconnect from your radio, you no longer need to use "pattern" with your CLI commands.  The default prompt of the device will be auto-matched.

New Member

EEM Applet -- Can you set an Env Var from an Applet?

Yes, it was just the last "#". 

I think I'm on my way now.

Thanks!

Tim
