Why each option
In Cisco's message logging system, the `debug` command output is categorized under severity level 7, which is specifically for debugging messages.
Debug commands typically generate a large volume of output and are intended for temporary troubleshooting; they should be manually disabled or may time out to prevent performance issues and excessive logging.
Cisco's syslog system assigns severity levels to messages, ranging from 0 (Emergencies) to 7 (Debugging). Output generated by `debug` commands provides detailed diagnostic information and falls under this highest numerical severity level, 7.
Debug commands are commonly available on AP CLI for detailed troubleshooting, although specific commands and their availability may vary by AP model and software version.
While WLCs have serial consoles for CLI access, the web interface primarily offers aggregated logs and monitoring tools, not direct `debug` command execution or its live output.
