RegEx command for config comparison NCM 7.7

Hello,

Hopefully someone will be able to help me with an issue I am having. I am trying to ignore a certain line of config from my config comparison but I have been unsuccessful so far. I am trying to exclude this line.

I have tired these as RegEx patterns but they do not work

^authentication mode hmac-sha-256*

^authentication mode.*

^_+authentication mode.*

Any help would be appreciated.

You might try the below as it should catch any white space that you may be overlooking. You may also replace all of the spaces with \s+ to ensure that is isn't a tab or some other white space.

^\s*authentication mode hmac-sha-256.*

Thanks for providing this information but when I applied the RegEX command I tested logging into our router and going into global config mode and then exiting to trigger a RCN and I can see that it did not change the effect of the config comparison. I still see that it marked it as a value that changed.

Can you explain a little more what you are trying to do? Are you talking about trying to ignore this line when the configuration changes? How are you currently trying to configure this, and where are you entering the RegEx?

Hello Bryan,

I am trying to get NCM to ignore the line in the screenshot above whenever a config comparison is done. I am trying to configure the RegEx in NCM settings under Comparison Criteria. Here is a screenshot of where I am configuring the RegEx at.
