Parameters
<hostname>
NTP peer hostname or IP address.
<ip-address>

Key identifier. The key ID values must be in the range 1 - 65534. You can specify multiple key IDs in the same list, separated by commas. When specifying multiple key IDs separated by commas, you must enclose them in quotes.
Usage
The no command option removes the authentication key from the NTP peer configuration.
NTP authentication involves three steps that you can perform in any order:
•  Configure a key ID using the ntp authentication command.
•  Add the configured key ID to the trusted keys list using the ntp authentication trusted-keys command.
•  Configure the NTP server or peer with the key ID using the ntp server key or ntp peer key command.
