Finding ACLs that are not needed in the configuration files using NCM rules

Hi Thwack Community!

 

I'm new to NCM and I want to check if it would be possible to find extra access-lists that are not part of our standard SNMP ACLs. Would it be possible to achieve this using strings or regular expressions only?

 

part of standard:
   access-list 10 permit 1.1.1.1

  access-list 10 permit 2.2.2.2

 

not part of standard:

access-list 10 permit 3.3.3.3

 

I read some articles and there seems to be an option to use the Comparison Criteria in NCM. I think we could enable some criteria to ignore our standard SNMP ACLs, and run a rule to find violations for lines that include 'access-list 10' in order to find the extra lines in ACL 10 that are not needed. I'm not sure if that would work since I haven't tested it. Also, we don't have admin access so I need to know if this is possible to achieve without using the Comparison Criteria. Any input would be appreciated. Thank you.
