SNTP: Viewing, Selecting, and Configuring
The following must be performed on the SNTP server:
■ The same authentication key-identifier, trusted key, authentication
mode and key-value that were configured on the SNTP client must
also be configured on the SNTP server.
■ SNTP server authentication must be enabled on the server.
If any of the parameters on the server are changed, the parameters have to be
changed on all the SNTP clients in the network as well. The authentication
check will fail on the clients otherwise, and the SNTP packets will be dropped.
Configuring the Key-Identifier, Authentication Mode, and
Key-Value
This command configures the key-id, authentication-mode, and key-value,
which are required for authentication. It is executed in the global configura-
tion context.

key-value <key-string> [trusted] no sntp authentication key-id <key-id>
Configures a key-id, authentication-mode (MD5 only), and
key-value, which are required for authentication.
The no version of the command deletes the authentication key.
