The command logging trap 4 is used to set the level of severity for syslog messages that should be sent to the console or logging buffer. Each level corresponds to a certain type of message, with severity levels ranging from 0 (emergency) to 7 (debugging).
In this case, the command sets the logging level to 4, which means that messages of severity levels 0 through 4 will be trapped. Therefore, the following levels will be trapped:
A. Emergency (Level 0): This is the most severe level, indicating an immediate action is required, such as system failure, power loss, or a critical application failure.
B. Alert (Level 1): Indicates an immediate action is needed, such as a loss of backup ISP connection, hardware errors, or severe application problems.
C. Critical (Level 2): Indicates a critical error condition that requires immediate attention, such as system process failures or loss of redundancy.
D. Error (Level 3): Indicates an error condition that should be addressed, such as routing failures or device hardware issues.
E. Warning (Level 4): Indicates a potential problem, such as high resource utilization or configuration issues that may lead to more severe errors.
Messages with severity levels 5 (notification), 6 (informational), and 7 (debugging) will not be trapped with this command.
