2.
Specify an NTP server for
the device.
• For IPv4:
sntp unicast-server
{ server-name | ip-address }
[ vpn-instance
vpn-instance-name ]
[ authentication-keyid
keyid | source interface-type
interface-number | version
number ] *
• For IPv6:
sntp ipv6 unicast-server
{ server-name |
ipv6-address }
[ vpn-instance
vpn-instance-name ]
[ authentication-keyid keyid
| source interface-type
interface-number ] *
By default, no NTP server is
specified for the device.
Repeat this step to specify
multiple NTP servers.
To use authentication, you must
specify the
authentication-keyid
keyid option.
To use an NTP server as the time source, make sure its clock has been synchronized. If the stratum
level of the NTP server is greater than or equal to that of the client, the client does not synchronize
with the NTP server.
Configuring SNTP authentication
SNTP authentication makes sure an SNTP client is synchronized only to an authenticated
trustworthy NTP server.
To make sure SNTP authentication can work, follow these guidelines on configuring SNTP
authentication:
• Enable authentication on both the NTP server and the SNTP client.
• Use the same authentication key ID, algorithm, and, key on the NTP server and SNTP client,
and specify the key as a trusted key on both the NTP server and the SNTP client. For
information about configuring NTP authentication on an NTP server, see "
Configuring NTP."
• On the SNTP client, associate the specified key with the NTP server. Make sure the server is
allowed to use the key ID for authentication.
With authentication disabled, the SNTP client can synchronize with the NTP server regardless of
whether the NTP server is enabled with authentication.
To configure SNTP authentication on the SNTP client:

3.
Configure an SNTP
authentication key.
• Release 1111:
sntp authentication-keyid keyid
authentication-mode md5
{ cipher | simple } value
• Release 1121 and later:
sntp authentication-keyid keyid
authentication-mode
{ hmac-sha-1 | hmac-sha-256 |
hmac-sha-384 | hmac-sha-512 |
md5 } { cipher | simple } string
By default, no SNTP authentication
key is configured.
