Ntp-Service Authentication Enable - HPE FlexNetwork 5130 HI Series Network Management And Monitoring Command Reference

• If none of the IPv4 ACLs specified for the access rights is created, the peer access right
applies.
• If none of the IPv4 ACLs specified for the access rights contains rules, no access right is
granted.
The ntp-service acl command provides minimal security for a system running NTP. A more secure
method is NTP authentication.
