Layer 3 Technologies

A network engineer is troubleshooting a flapping (up/down) interface on a core switch that is synchronized with an NTP server. The current log output does not display the flap time.

Which command enables switch logging to show the flap time according to the device clock?

  • A service timestamps log uptime
  • B clock summer-time mst recurring 2 Sunday mar 2:00 1 Sunday nov 2:00
  • C service timestamps log datetime localtime show-timezone
  • D clock calendar-valid
Explanation

service timestamps log datetime localtime show-timezone timestamps log messages using the device’s local clock time and includes the time zone. NTP synchronization ensures that device clock is accurate.
