Hi @dtccsundar,

if you want only one regex, you can use

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

if you prefer two regexes, you can use:

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

you can test the regx at https://regex101.com/r/WpmBG3/1
