The output of this command includes the following parameters:

Parameter

Description

authentication

Indicates if authentication is enabled for the NTPNetwork Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. server.

time since restart

Time in hours since the system was last rebooted.

time since reset

The number of seconds since the last time the local NTPNetwork Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. server was restarted.

packets received

Total number of packets received.

packets processed

Number of packets received in response to previous packets sent.

current version

Number of packets matching the current NTPNetwork Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. version.

previous version

Number of packets matching the previous NTPNetwork Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. version.

declined

Number of packets declined.

access denied

Number of packets for which access has been denied.

bad length or format

Number of packets with invalid length, format or port number.

packets received

Total number of packets received.

bad authentication

Number of NTPNetwork Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. packets that failed to be authenticated.

rate exceeded

Number of packets discarded due to rate limitation.

system peer

The IP address of the peer NTPNetwork Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. server.

system peer mode

The peer mode of this remote association:

Symmetric Active

Symmetric Passive

Client

Server

Broadcast

leap indicator

This parameter indicates whether or not a leap-second should be inserted or removed at the end of the last day of the current month.

00 no warning

01 +1 second (following minute has 61 seconds)

10 -1 second (following minute has 59 seconds)

stratum

The stratum level of the peer

precision

The advertised precision of the switch. This value can range from -4 and -20, inclusive.

root distance

Total round trip delay to the stratum 1 reference clock.

root dispersion

Total dispersion to the stratum 1 reference clock. This value is a cumulative measure of all errors associated with the network hops and servers between the NTPNetwork Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. server and its stratum 1 server.

reference ID

IPv4/IPv6 address of the remote NTPNetwork Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. server.

Note: When NTPNetwork Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. server is reachable through IPv4 address, use the address as is. If done through IPv6 address, the Reference ID is calculated instead of directly taking the IPV6 address on the NTPNetwork Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. Server. The controller performs a MD5Message Digest 5. The MD5 algorithm is a widely used hash function producing a 128-bit hash value from the data input. checksum and the last 4 bytes are considered as the reference ID.

reference time

Time when the local system clock was last set or corrected, in NTPNetwork Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. timestamp

format.

system flags

This parameter displays any flags configured for this NTPNetwork Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. entity.

jitter

The average magnitude of jitter between several time queries.

stability

The average magnitude of offset between several time queries

broadcastdelay

The broadcast delay of this NTPNetwork Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. server association, in seconds.

authdelay

The authentication delay of this NTPNetwork Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. server association, in seconds.
