Version 1.1 Oct 1 2018

Purpose
=======
This script will capture information of the RPD, this is ran from a command line
an alias can be used to call the full command

 


How to install
==============

A- Create a directory for scripts (if not done yet)
router#cd harddisk:
router#mkdir EEM

B- copy the script sh_tech_rpd.tcl in harddisk:EEM/

 

2 configure IOS
===============
Mandatory event manager configuration:
event manager directory user policy "harddisk:/EEM"
event manager policy sh_tech_rpd.tcl type user
or
event manager policy sh_tech_rpd.tcl type user authorization bypass


Security note :
----------------
The EEM script will be subject to authorization, in case aaa authorization is configured
make sure EEM as enough privilege to execute command
you can also use the "authorization bypass" keywords as shown above


3 How to run
=============
from the router exec type:
event manager run sh_tech_rpd.tcl -r [ip address of the RPD]

example :
---------
cbr8_prompt#event manager run sh_tech_rpd.tcl -r 172.16.1.1
The above start the collection of show command on the rpd registered with IP address 172.16.1.1


4 Options
=========
Additional to -r option which is mandatory, there are the following other options

-v This option is to enter the VRF name in which the RPD is accessible

-m This set the message level
0 Display error (this is on by default)
1 Display info in the syslog
2 Display script debugging in the syslog

-c This option provide the file name where additional command can be requested on the RPD as well as the Supervisor
example of file coding:

# This line is a comment, the script will not look at it
# Every line starting with SHOW_CMD_RPHY will act on the rpd
# Every line starting with SHOW_CMD_SUP will act on the supervisor
#
#

##Test the rphy capture
SHOW_CMD_RPHY show downstream channel configuration

##Test the supervisor capture
SHOW_CMD_SUP show cable modem cable 6/0/1 flap

note you can paste the above into a file, send it to the cbr8 and calling the -c option, you will see that the
script will capture those additionally

-t This option provide the type of sh tech
basic In this case logging and show version is captured
This is useful in case the developer would only need a few commands, in that case there is no
need to capture all he sh tech, you could correlate -t basic with -c [file with command requested by the devloper]
