Configuring Access Control Right - H3C S5100-SI Series Operation Manual

Operation Manual – NTP
H3C S5100-SI/EI Series Ethernet Switches
Note:
A multicast server can synchronize multicast clients only after its clock has been
synchronized.
An S5100-SI/EI series switch working in the multicast server mode supports up to
1,024 multicast clients.
I. Configuring a switch to work in the multicast server mode
Follow these steps to configure a switch to work in the NTP multicast server mode:
Enter system view
Enter VLAN interface view
Configure the switch to
work in the NTP multicast
server mode
II. Configuring a switch to work in the multicast client mode
Follow these steps to configure a switch to work in the NTP multicast client mode:
Enter system view
Enter VLAN interface view
Configure the switch to
work in the NTP multicast
client mode

1.4 Configuring Access Control Right

With the following command, you can configure the NTP service access-control right to
the local switch for a peer device. There are four access-control rights, as follows:
query: Control query right. This level of right permits the peer device to perform
control query to the NTP service on the local device but does not permit the peer
device to synchronize its clock to the local device. The so-called "control query"
refers to query of state of the NTP service, including alarm information,
authentication status, clock source information, and so on.
