A network operations team requires a Cisco IOS router to send only high-criticality log messages—specifically Emergency (severity 0), Alert (severity 1), and Critical (severity 2)—to a central syslog server at IP address 10.1.1.50. Simultaneously, the router must retain all messages up to the Informational level (severity 6) in local system RAM. Which set of commands correctly achieves this configuration?
- logging host 10.1.1.50
logging trap 2
logging buffered 6Cevap - Blogging host 10.1.1.50
logging trap 6
logging buffered 2 - Clogging server 10.1.1.50
logging monitor 2
logging buffered 6 - Dlogging host 10.1.1.50
logging trap 2
terminal monitor 6
Cevap
The configuration using 'logging host 10.1.1.50', 'logging trap 2', and 'logging buffered 6' correctly configures the destination IP, syslog trap threshold, and local RAM buffer logging levels.
The correct command combination specifies 'logging host 10.1.1.50' to define the remote syslog server, 'logging trap 2' to forward events at or above Critical severity (levels 0, 1, and 2), and 'logging buffered 6' to store messages up to Informational severity (levels 0 through 6) in the local memory buffer.
