%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up
A. アラート
B. クリティカル
C. エラー
D. 通知
Correct Answer: D
Explanation:
Cisco routers, switches, PIX and ASA firewalls prioritize log messages into 8 levels (0-7), as shown
below: LevelLevel NameDescription 0 Emergencies System is unusable 1 Alerts Immediate action
needed 2 Critical Critical conditions 3 Errors Error conditions 4 Warnings Warning conditions 5
Notifications Informational messages 6 Informational Normal but significant conditions 7 Debugging
Debugging messages
When you enable logging for a specific level, all logs of that severity and greater (numerically less)
will be logged. In this case we can see that logging level of 3 (as seen by the 3 in "LINK-3- UPDOWN")
and level 5 (as seen by the 5 in "LINEPROTO-5-UPDOWN") are shown, which means that logging
level 5 must have been configured. As shown by the table, logging level 5 is Notifications.
