Hi Mario,
I see. I don't know any freeware software for such configuration compliance tasks.
If you want to have some kind of automation you could
Download your running-configs to a TFTP server and use grep or a more advanced script to extract the lines your're looking for (the TFTP download could also be done by that scipt =>SNMP)
Use TCL if your devices support it
A simple example:
R1#show int loop0 descriptionInterface                      Status         Protocol DescriptionLo0                            up             up       TESTR1#tclshR1(tcl)#puts [regexp {test} [exec "show int loop0 descr"]]0R1(tcl)#puts [regexp -nocase {test} [exec "show int loop0 descr"]]1R1(tcl)#tclquit
There's a section for EEM scripting, so if you want to create a custom command for your needs, you'll get help there.
Best regards
