Configure NTP server settings, authentication, timezone, and service status using CLI commands.

Configure Network Time Protocol (NTP) settings to ensure accurate time synchronization on the device.

NTP configuration includes setting up server addresses, authentication methods, timezone settings. Proper NTP configuration ensures time synchronization across network devices.

Procedure

	1.	Use the configure ntp server string command to configure the NTP server address. Example: `Device# configure ntp server 192.168.216.201` String - IP address or domain name.
	2.	Use the configure ntp authentication command to configure NTP authentication. Example: `Device# configure ntp authentication none Device# configure ntp authentication md5 <password> <keyid> Device# configure ntp authentication sha1 <password> <keyid>` none - disables the NTP authentication md5\|sha1 - authentication method. Note Optional, the md5 password and keyid should match NTP server's md5 password and keyid. To configure a new password using a GUI or CLI, the password should match the following criteria: The password length range is from 8 to 20 characters. The following special characters are not allowed: ' (apex) " [double apex] ` [backtick] $ [dollar] = [equal] \ [backslash] # [number sign] whitespace Example: `Device# configure ntp authentication md5 test1234 65535`
	3.	Use the configure ntp {enable \| disable} command to enable or disable the NTP service. Example: `Device# configure ntp enable`
	4.	Use the configure ntp timezone string command to configure the NTP timezone. Example: `Device# configure ntp timezone Asia/Shanghai`
	5.	Use the show ntp config command to validate the NTP configuration and status. Example: `Device# show ntp config NTP status: enabled NTP server: 192.168.216.201 authentication: MD5 password: test123 keyid: 5 timezone: Asia/Shanghai`
	6.	Use the show ntp command to check if device can sync up time with NTP server. Example: `Device# #show ntp Stratum Version Last Received Delay Offset Jitter NTP server 1 4 9sec ago 1.840ms -0.845ms 0.124ms 192.168.216.201`
