EEM Script Evaluation

Hello Community,

Can someone please take a look at the script below and tell me why on earth the simple script won't work when I try to run it manually,

event manager applet netflow_toptalk

event none

action 1.0 cli command "enable"

action 2.0 cli command "conf t"

action 3.0 cli command "flow record flowrecord1"

action 4.0 cli command "match ipv4 protocol"

action 5.0 cli command "match ipv4 tos"

action 6.0 cli command "match ipv4 source address"

action 7.0 cli command "match ipv4 destination address"

action 8.0 cli command "match transport source-port"

action 9.0 cli command "match transport destination-port"

action 10.0 cli command "match flow direction"

action 12.0 cli command "match interface input"

action 13.0 cli command "match interface output"

action 14.0 cli command "collect application name"

action 15.0 cli command "collect timestamp sys-uptime first"

action 17.0 cli command "flow monitor flowmonitor1"

action 18.0 cli command "cache timeout active 86520"

action 19.0 cli command "cache entries 32768"

action 20.0 cli command "record FlowRecord1"

action 22.0 cli command "alias exec toptalkers event manager run toptalkers.tcl"

action 22.0 cli command "end"

The is the debug

You've fallen into the trap of thinking the action labels are numbers when they are actually strings.  Do a show run, and you'll see the actual order the actions will run.  Action labels are evaluated in lexicographical order, so you'll need to rethink your number strategy so that each action executes in the correct order.  Typically preceeding actions with zeros works:

001

002

003

...

010

...

Thanks Joseph,

I was going crazy!

Hi Joeseph,

Other than the number strategy you provided can you let me know what numbering strategies are commonly used.

I tried the following but it didn't work:

event manager applet netflow_server

event none

action 1.1 cli command "enable"

action 2.1 cli command "conf t"

action 3.1 cli command "flow record FlowRecord1"

action 4.1 cli command "match ipv4 protocol"

action 5.1 cli command "match ipv4 tos"

action 6.1 cli command "match ipv4 source address"

action 7.1 cli command "match ipv4 destination address"

action 8.1 cli command "match transport source-port"

action 9.1 cli command "match transport destination-port"

action 10.1 cli command "match flow direction"

action 12.1 cli command "match interface input"

action 13.1 cli command "match interface output"

action 14.1 cli command "collect application name"

action 15.1 cli command "collect timestamp sys-uptime first"

action 16.1 cli command "exit"

action 17.1 cli command "flow monitor FlowMonitor1"

action 18.1 cli command "cache timeout active 86520"

action 19.1 cli command "cache entries 32768"

action 20.1 cli command "record FlowRecord1"

action 21.1 cli command "event manager run netflow_server"

Kind regards

As I said you need to normalize your numbering by, for example, preceeding each with leading zeros.

001

002

...

010

...

020

Joseph,

I get it - I'm being a numbty today. However, can you tell me why the following line of the script doesn't work:

if [catch {cli_exec $cli1(fd) "event manager run talkerstop.tcl"} _cli_result] {

    error $_cli_result $errorInfo

}

Basically, I would like the script to automatically be run at the end.

Because you're still in config mode when you run this command.  You need to exit from config mode first.

Joseph,

I made the change as you suggested, however I still can only get the script to run by manually running

event manager run toptalkers.tcl.

You didn't have it written this way before.  But no that I see what you're trying to do, it will not work.  You cannot have the script call itself like this.  That will be an infinite loop.  Why do you want to do this?
