Question
Observe the output from a Cisco IOS router. Which messages will be logged to buffer?logging on!logging buffered warnings!logging trap debugginglogging host 172.16.200.51levels 4 through 7levels 5 through 0levels 4 through 0levels 5 through 7
Solution
The configuration provided indicates that the router is set to log warning messages and above to the buffer. The "logging buffered warnings" command sets the severity level for messages to be logged in the buffer. In Cisco IOS, the severity levels are:
0 - emergencies 1 - alerts 2 - critical 3 - errors 4 - warnings 5 - notifications 6 - informational 7 - debugging
The "warnings" level includes levels from 0 to 4. Therefore, emergencies, alerts, critical, errors, and warnings will be logged to the buffer. The "logging trap debugging" command is not relevant to the buffer logging, it sets the level of messages to be sent to an external syslog server.
