NOTE: If you attach a unit to a stack and its template does not match the stack's template, then the new unit will automatically reboot using the template used by the management unit. To avoid the automatic reboot, you may first set the template to the template used by the management unit. Then power off the new unit, attach it to the stack, and power it on. If the IPv4 Routing or IPv4 Data Center template is currently in use and you attempt to configure IPv6 routing features without first selecting the Dual IPv4-IPv6 Routing template, the IPv6 commands do not take effect. IPv6 features are not available when an IPv4-only template is active. Why is the System Time Needed? The switch uses the system clock to provide time stamps on log messages. Additionally, some show commands include the time in the command output. For example, the show users login-history command includes a Login Time field. The system clock provides the information for the Login Time field. How Does SNTP Work? SNTP assures accurate switch clock time synchronization. Time synchronization is performed by a network SNTP server. Managing General System Settings 281
