R211x-HP Flexfabric 11900 Network Management and Monitoring Command Reference

24
The output shows that server 127.0.0.1 is synchronized to server 3000::32, and server 3000::32 is
synchronized to the local clock.
Table 10 Command output
Field Descri
p
tion
Server IP address of the NTP server.
Stratum Stratum level of the NTP server.
jitter
Root mean square (RMS) value of the clock offset relative to the upper-level clock, in
seconds.
synch distance
Synchronization distance relative to the upper-level NTP server, in seconds,
calculated from dispersion and roundtrip delay values.
RefID
Identifier of the primary reference source. When the stratum level of the primary
reference clock is 0, it is displayed as Local. Otherwise, it is displayed as the IP
address of the primary reference clock.
ntp-service acl
Use ntp-service acl to configure the access-control right for peer devices to access NTP services of the
local device.
Use undo ntp-service acl to remove the configured NTP service access-control right.
Syntax
ntp-service { peer | query | server | synchronization } acl acl-number
undo ntp-service { peer | query | server | synchronization } acl acl-number
Default
The access-control right for the peer devices to access the NTP services of the local device is peer.

Parameters
peer: Allows time requests and NTP control queries (such as alarms, authentication status, and time
server information) from a peer device and allows the local device to synchronize itself to a peer device.
query: Allows only NTP control queries from a peer device to the local device.
server: Allows time requests and NTP control queries from a peer device, 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.
acl acl-number: Specifies an ACL. The peer devices that match the ACL have the access right specified in
this command. The acl-number argument represents a basic ACL number in the range of 2000 to 2999.
