Ntp-Service Ipv6 Dscp - HPE FlexNetwork 5130 HI Series Network Management And Monitoring Command Reference

query: Allows only NTP control queries from a peer device to the local device.
server: Allows time requests and NTP control queries, but does not allow the local device to
synchronize itself to a peer device.
synchronization: Allows only time requests from a system whose address passes the access list
criteria.
ipv6-acl-number: Specifies an IPv6 ACL by its number. The peer devices that match the IPv6 ACL
have the access right specified in the command. The ipv6-acl-number argument represents a basic
IPv6 ACL number in the range of 2000 to 2999 or an advanced IPv6 ACL number in the range of
3000 to 3999.
Usage guidelines
When the device receives an IPv6 NTP request, it matches the request against the access rights in
the order from the least restrictive to the most restrictive: peer, server, synchronization, and
query.
• If no IPv6 NTP access control is configured, the peer access right applies.
• If the IP address of the peer device matches a permit statement in an IPv6 ACL, the access
right is granted to the peer device. If a deny statement or no IPv6 ACL is matched, no access
right is granted.
• If no IPv6 ACL is specified for an access right or the IPv6 ACL specified for the access right is
not created, the access right is not granted.
• If none of the IPv6 ACLs specified for the access rights is created, the peer access right
applies.
• If none of the IPv6 ACLs specified for the access rights contains rules, no access right is
granted.
The ntp-service ipv6 acl command provides a minimum security method. NTP authentication is
more secure.
Examples
# Configure the peer devices on subnet 2001::1 to have full access to the local device.
<Sysname> system-view
[Sysname] acl ipv6 basic 2001
[Sysname-acl-ipv6-basic-2001] rule permit source 2001::1 64
[Sysname-acl-ipv6-basic-2001] quit
[Sysname] ntp-service ipv6 peer acl 2001
