Network Time Protocol

MediaNivel 1Automatizadaarista-eos

Descripción

EOS enables Network Time Protocol (ntp) on the switch by default, and time settings from any properly configured ntp server override the manual setting of the system clock. ntp servers synchronize time settings of systems running an ntp client. The switch supports ntp versions 1 through 4, and uses version 4 by default. Without synchronized time accurately correlating information between devices becomes difficult, if not impossible. If logs cannot be successfully compared between each of the routers, switches, and firewalls, it will be very difficult to determine the exact ... Audited against the output of 'show running-config' (not 'show running-config all').
