Set authority to access the NTP services on a local Ethernet Switch. This is a basic
and brief security measure, compared to authentication. An access request will be
matched with
peer, serve, serve only, and query only in an ascending order of
the limitation. The first matched authority will be given.
Example
Give the authority of time request, query control and synchronization with the
local equipment to the peer in ACL 76.
[SW7700]ntp-service access peer 76
Give the authority of time request and query control of the local equipment to the
peer in ACL 28.
