Inline field extraction with rex

[lukejadamec]

I'm not a big regex power yet, I know this is easy, but since it is not on a system I can't test and figure out myself I'm looking for expert assistance.
Can someone provide a search rex that will pull both the interface and up-down fields from this log?

Looking for a rex that pulls two fields:

search | rex field=_raw ?(?<interface>?)?(?<up-down>?)? | stats count by interface,up-down

Thanks,

Luke

Here

mysearch | rex "Interface (?<interface>[^, ]*), changed state to (?<state>\w+)" | table interface state
