Description on the fields of the
display ntp-service sessions
command
Field
Description
source
IP address of the synchronization source
reference
Reference clock ID of the synchronization source
1) If the reference clock is the local clock, the value of this field is
related to the value of the
stra
field:
z
When the value of the
stra
field is 0 or 1, this field will be “LOCL”;
z
When the
stra
field has another value, this filed will be the IP
address of the local clock.
2) If the reference clock is the clock of another switch on the
network, the value of this field will be the IP address of that
switch.
stra
Stratum of the clock of the synchronization source
reach
Reachability count of the clock source. 0 indicates that the clock
source is unreachable
poll
Polling interval in seconds, that is, the maximum interval between
two successive messages
now
Time elapsing since the last NTP packet is sent
offset
The offset of the system clock relative to the reference clock, in
milliseconds
delay
Network delay, that is, the roundtrip delay from the local switch to
the clock source, in milliseconds
disper
Maximum offset of the local clock relative to the reference clock
[12345]
1: Clock source selected by the system, namely the current
reference source, with a system clock stratum level smaller than or
equal to 15
2: Stratum level of this clock source is smaller than or equal to 15
3: This clock source has passed the clock selection process
4: This clock source is a candidate clock source
5: This clock source was created by a configuration command
