User Guidelines
The SNTP authentication parameter is an MD5 checksum sent to the NTP
server. The key index identified in the sntp server command should be
configured with the sntp authentication-key command.
The hostname parameter may be a fully or partially qualified domain name. A
hostname consists of a series of labels separated by periods. Each label may be
a maximum of 63 characters in length. A maximum length of the hostname
parameter is 256 characters. Refer to RFC 1035 Section 2.3.1 for more
