Debug Condition Command Restrictions in Cisco IOS
The debug condition command in Cisco IOS is designed to restrict debug output for specific interfaces. While it allows parameters such as IP addresses, the command may require an interface to be specified for proper functionality. The behavior of this command might vary across different IOS versions, potentially showing no output in some cases. When using the debug condition command, it's important to include the interface along with other parameters to ensure the desired debugging output is generated.
