RegEx Help match string except when

Hey all,

I am hoping someone out there can help me fix my RegEx string. I am searching for all interfaces with a particular description except I want to exclude when the description contains a (dot) followed by a decimal number. I would think the could be written like this.

"interface.*\n.*description DS[13][^\.]"

An example of an interface that should be included by the RegEx search.
interface Multilink1
description DS1NT-1234567

An example of an interface that should be excluded by the RegEx search.
interface Serial0/0/0
description DS1NT-1234567.01

I presume its using Multiline to match, if so I'd expect this to work:

^interface.*\n\s+description DS[13][\w-]+\d+[^\.]\d+$

is this for policy rules?
if so, it might be easier to use "match block" which would search each interface block of code ->
start of block:
^interface s.*

end of block:
^!
where ^ means beginning of line

then your logic would be
regex matching:
description DS[1,3]\.[0-9]

you'll have to tweak for your specific env, but hopefully that helps

Thank you. This matched all my WAN interfaces perfectly and excluded all interfaces bound into a mlppp interface.

^interface.*\n\sdescription DS[13][\w-]+\d+[^\.\d]+$
