Display Local Server Information
The 
ntpinfo
 command is used to display information about the local switch’s implementation 
of 
NTP
. To view local switch 
NTP
 information, enter the 
ntpinfo
 command at the system 
prompt. A screen similar to the following is shown:

Field Descriptions
The following section explains the fields shown using the 
ntpinfo
 command.
System peer.
 The 
IP
 address of the switch.
System peer mode
. The peer mode of this remote association. There are five possible modes: 
symmetric active, symmetric passive, client, server, and broadcast. The displayed mode is 
assumed if this association becomes the switch’s host 
NTP
 server. For a description of the 
Leap indicator
. The status of leap second insertion for this association. Leap seconds are 
seconds that are added to the timestamp of an 
NTP
 entity to correct accumulated time errors. 
The possible values are:
00
No warning.
01
Last minute has 61 seconds.
10
Last minute has 59 seconds.
11
Alarm condition (clock not synchronized)
Stratum
. The stratum level of the remote peer. If this number is 
16
, the remote peer has not 
been synchronized.
Precision
. The advertised precision of the switch. It will be a number between -4 and -20.
Root distance
. This is a signed fixed-point number indicating the total roundtrip delay to the 
primary reference source at the root of the synchronization subnet, in seconds. Note that this 
variable can take on both positive and negative values, depending on clock precision and 
skew.
Rootdispersion
. This is a signed fixed-point number indicating the maximum error relative to 
the primary reference source at the root of the synchronization subnet, in seconds. Only posi-
tive values are possible.
Reference ID
. This is a 32-bit code identifying the particular reference clock. In the case of 
stratum 0 (unspecified) or stratum 1 (primary reference source), this is a four-octet, left-justi-
fied, zero-padded 
ASCII
 string. In the case of stratum 2 and greater (secondary reference) this 
is the four-octet Internet address of the peer selected for synchronization.
