Ntp-Service Authentication Enable - 3Com Switch 4500 Family Manual

NTP service access-control rights from the highest to the lowest are peer, server, synchronization,
and query. When a local NTP server receives an NTP request, it will perform an access-control right
match and will use the first matched right.
The ntp-service access command only provides a minimal degree of security measure. A more secure
way is to perform identity authentication.
Refer to the ntp-service authentication enable command for related configuration.
Examples
# Configure the access right from the remote device in ACL 2076 to the local NTP server as peer.

# Configure the access right from the remote device in ACL 2028 to the local NTP server as server.
