Regex Editor & Tester

This regex matches Cisco IP Phone device identifiers in the format CP-XXXXXX-SEPYYYYYYYYYYYY, where the first segment is 1-6 alphanumeric characters (often the model or product code) and the second segment is exactly 12 hexadecimal digits representing the phone's MAC address. It is useful for validating or extracting these identifiers from configuration files, logs, or inventory systems.
