NTP
Network Time Protocol (NTP) is defined in RFC 1305, Network Time Protocol
(Version 3) Specification, Implementation and Analysis. It enables participating
network nodes to keep time more accurately and maintain time in a synchronized
manner between all participating network nodes.
NTP time elements include:
• Authentication-check
• Authentication-key
• Broadcast
• Broadcastclient
• NTP-Server
• Peer
• Server
Authentication-check
The authentication-check command provides the option to skip the rejection of
NTP PDUs that do not match the authentication key or authentication type
requirements. The default behavior when 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.
CLI Syntax: config>system>time>ntp
authentication-check
The following example shows the command usage to authenticate NTP PDUs on
receipt.
