NEC N8406-022 NTP server configuration, no ntp prisrv <IP address>, no ntp secsrv <IP address>

IMPORTANT: If TACACS+ is enabled, you must login using TACACS+ authentication when connecting via the console or Telnet/SSH/HTTP/HTTPS. Backdoor for console is always enabled, so you can connect using notacacs and the administrator password even if the backdoor (telnet) or secure backdoor (secbd) are disabled.

If Telnet backdoor is enabled (telnet ena), type in notacacs as a backdoor to bypass TACACS+ checking, and use the administrator password to log into the switch. The switch allows this even if TACACS+ servers are available.

If secure backdoor is enabled (secbd ena), type in notacacs as a backdoor to bypass TACACS+ checking, and use the administrator password to log into the switch. The switch allows this only if TACACS+ servers are not available.

NTP server configuration

These commands enable you to synchronize the switch clock to a Network Time Protocol (NTP) server. By default, this option is disabled.

The following table describes the NTP Server Configuration commands.

Table 60 NTP Server Configuration commands

Command	Description
[no] ntp prisrv <IP address>	Prompts for the IP addresses of the primary NTP server to which you
	want to synchronize the switch clock. For example, 100.10.1.1
	Command mode: Global configuration
[no] ntp secsrv <IP address>	Prompts for the IP addresses of the secondary NTP server to which
	you want to synchronize the switch clock. For example, 100.10.1.2
	Command mode: Global configuration
ntp interval <1-44640>	Specifies the interval, in minutes (1-44640), to resynchronize the
	switch clock with the NTP server. The default is 1440 seconds.
	Command mode: Global configuration
ntp timezone <hh:mm>	Configures the NTP time zone offset from Greenwich Mean Time
	(GMT), in hours and minutes. The offset format is HH:MM.
	Command mode: Global configuration
[no] ntp daylightsavings	Disables or enables daylight saving time in the system clock. When
	enabled, the switch will add an extra hour to the system clock so that
	it is consistent with the local clock. By default, this option is disabled.
	Command mode: Global configuration
ntp enable	Enables the NTP synchronization service.
	Command mode: Global configuration
no ntp enable	Disables the NTP synchronization service. This is the default.
	Command mode: Global configuration
show ntp	Displays the current NTP service settings.
	Command mode: All
