R211x-HP Flexfabric 11900 Network Management and Monitoring Command Reference

Usage guidelines

When a device is operating in NTP broadcast or multicast server mode, the display ntp-service sessions

command does not display the IPv4 NTP association information corresponding to the broadcast or

multicast server, but the associations are counted in the total number of associations.

Examples

# Display brief information about all IPv4 NTP associations.

Field Descri

tion

source

• When the reference clock is the local clock, the field displays LOCAL

(number), which indicates that the IP address of the local clock is

127.127.1. number, where number represents the NTP process number in the

range of 0 to 3.

• When the reference clock is the clock of another device, the field displays

the IP address of the NTP server. If this field displays 0.0.0.0, the IP address

of the NTP server has not been resolved successfully.

reference

Reference clock ID of the NTP server:

• If the reference clock is the local clock, the value of this field is related to the

value of the stra field:

{ When the value of the stra field is 0 or 1, this field displays LOCL.

{ When the stra field has another value, this field displays the IP address

of the local clock.

• If the reference clock is the clock of another device on the network, this field

displays the IP address of the device. If the device supports IPv6, this field

displays the MD5 digest of the first 32 bits of the IPv6 address of the device.

If this field displays INIT, the local device has not established a connection

with the NTP server.

stra

Stratum level of the clock source, which determines the clock accuracy. The

value is in the range of 1 to 16. The clock accuracy decreases from stratum 1

to stratum 16. A stratum 1 clock has the highest precision, and a stratum 16

clock is not synchronized and cannot be used as a reference clock.

reach

Reachability count of the clock source. 0 indicates that the clock source is

unreachable.

poll

Polling interval in seconds. It is the maximum interval between successive NTP

messages.
