Script Info URL:

How many times have you wanted to do "show run | inc snmp | redirect flash:/snmp.cfg"? Up until now this wasn't possible because IOS only supports one pipe. The other pipes are treated as part of the argument to the first pipe command. The cl_multi_pipe.tcl EEM policy enables the support for multiple command pipelines. You can run as many pipe commands as you want.

hi..this is my problem...

I want to sent output command from switch to ftp server..Below are the step that i have done :

1- Copy script cl_multi_pipe.tcl to my switch (Cisco catalyst WS-C3560E-12SD , IOS : 12.2(55)SE)

C3560G#dir

Directory of flash:/

2 -rwx 3096 Oct 28 2011 23:59:02 +08:00 multiple-fs

3 -rwx 3857 Oct 28 2011 23:59:02 +08:00 private-config.text

4 -rwx 5716 Oct 28 2011 23:59:01 +08:00 config.text

5 -rwx 8916 Jul 25 2011 16:12:38 +08:00 vlan.dat

443 -rwx 4524 Nov 18 2011 15:09:34 +08:00 cl_multi_pipe.tcl

6 drwx 512 Nov 12 2010 15:31:05 +08:00 c3560e-universalk9-mz.122-55.SE

57931776 bytes total (39990272 bytes free)

2- Create event manager directory & policy

C3560G#sh ru | b event

event manager directory user policy "flash:/"

event manager policy cl_multi_pipe.tcl

!

end

3- At the same time i already configure kron & command to push text file to my ftp server

kron occurrence PipeOut at 15:00 sun recurring

policy-list PipeOut

!

kron policy-list PipeOut

cli show version | i uptime | redirect ftp://172.17.30.1/uptime.txt

4- Description for all above step.

- I start with configure step 3 to gather information about switch uptime

- Switch will kron text file every sunday at 15:00pm to ftp server

- This task cannot be done because kron cannot accept double pipe ( i guest ?)

- The idea is to use Cisco EEM features to do the double pipe command.

- My problem :: How to configure EEM so that the task will run automatically just like kron schedule ?

Please advice.

Thanks

Hi Joe,

I've used this script in the past on other equipment without an issue, but I'm having some difficulty now. Any ideas of what the problem is?

881W-Router#dir flash: | i .tcl
7 -rw- 0 Aug 24 2014 16:20:24 +00:00 cl_multi_pipe.tcl

881W-Router#show run | i event
event manager directory user policy "flash:/"

881W-Router(config)#event manager policy cl_multi_pipe.tcl
EEM Register event failed: Error unable to parse EEM policy for registration commands.

EEM configuration: failed to retrieve intermediate registration result for policy cl_multi_pipe.tcl

I'm interpreting this as having EEM version 4.00

Cory-

Did you ever find a fix for this? I'm getting the same result.

Henrique Ferreira · ‎03-04-2019

I know this is an old thread, but i had the same issue and the solution was applying the following command:

event manager directory user policy "flash:/"

TCL worked flawlessly. Thank you.

Old thread, but has anyone figured out how to get this to work ? currently cant get it to work on 3850 , Event manger version 4.00
