func NormalizeMAC ¶ added in v1.2.0

func NormalizeMAC(mac string) string

NormalizeMAC parses a MAC address string and returns its canonical lowercase colon-separated form (e.g. "aa:bb:cc:dd:ee:ff"). Handles colon-separated, hyphen-separated, and dot-separated (Cisco) formats, as well as mixed casing. If the input is not a valid MAC, it is returned unchanged so that downstream validation can report the real error.
