CONFIGURATION GUIDE RELEASE 22.9.R1
System management
authentication is configured is to reject all NTP PDUs that have a mismatch in either the authentication
key-id, type, or key.
When authentication-check is configured, NTP PDUs are authenticated on receipt. However,
mismatches cause a counter to be incremented, one counter for key-id, one for type, and one for key value
mismatches.
Use the following CLI syntax to authenticate NTP PDUs on receipt.
config>system>time>ntp
authentication-check
Example: Command usage to authenticate NTP PDUs on receipt
config>system>time>ntp#
config>system>time>ntp# authentication-check
config>system>time>ntp# no shutdown
6.14.1.3.3.2 Authentication-key
This command configures an authentication key ID, key type, and key used to authenticate NTP PDUs

Use the following CLI syntax to configure an authentication key ID, key type, and key.
config>system>time>ntp
authentication-key key-id {key key} [hash | hash2] type
{des|message-digest}
Example: Command usage
The following example shows the command usage to configure an authentication key ID, key type, and
key.
config>system>time>ntp#
config>system>time>ntp# authentication-key 1 key A type des
config>system>time>ntp# no shutdown
Example: Configuration output
The following sample configuration shows NTP disabled with the authentication-key parameter enabled.
A:sim1>config>system>time>ntp# info
