show ntp

Displays information about all of the NTP servers currently peered with CNA.

show ntp [ association | status ]
 
         [ | { include | exclude | begin } <exp> ] 
 
         [ > <url> ]
 

• exp--a regular expression, to be used as a filter
• url--destination for output

System operations mode, login-level privileges.

Output from the show ntp command is generated by a call to the ntpq query utility. More information about this utility and its output is available at http://www.ntp.org.

Use the status keyword to display the current timing status with the synchronized peer. Output, which is generated by calling the ntpq utility with a -p option, will look similar to the following:

   remote     refid     st t when poll reach   delay   offset    disp
 
========================================================================
 
*LOCAL(1)  LOCAL(1)     10 l   49   64  377     0.00    0.000   10.01
 

 

Columns identify the following:

• remote--NTP server and peers defined in the CNA configuration; in the example, there are no NTP peerings configured, so time synchronization is provided by the management module, shown as LOCAL
• refid--current source of synchronization, again LOCAL for the management module.
• st--NTP stratum.
• t--NTP type; can be one of the following:
• u--unicast
• m--multicast
• l--local
• - --don't know
• poll--polling interval, in seconds
• when--number of seconds since peer was last heard
• reach--octal value representing status of reachability register (see RFC-1305)
• delay--latest delay, in milliseconds (ms)
• offset--latest offset in ms
• disp--latest jitter (dispersion) in ms

The association keyword displays the output of a call to the ntpq utility with the -c association option. This output will look similar to the following:

ind assID status  conf reach auth condition  last_event cnt
 
===========================================================
 
  1 33732  9614   yes   yes  none  sys.peer   reachable  1
 

 

Each line in the association table corresponds to a line in the status table, where each line represents an NTP server or peer.

Columns identify the following:

• ind--index number
• assID--unique identifier for each mobilized association
• status--hex number indicating peer status, defined in the NTP specification
• conf, reach, auth, condition, last_event, and cnt--shows data decoded from the status word, as defined in RFC-1305 (sys.peer in the condition column identifies the system peer, the server which is currently providing synchronization; this should correspond to the line identified by an asterisk, *, in the status table)

You can pipe the command through one of the following filters:

• include--shows all lines in the output which contain a match to the specified regular expression
• exclude--shows all lines in the output except those which contain a match to the specified regular expression
• begin--shows all lines in the output beginning with the first match to the specified regular expression

The vertical-line pipe character | is required when a filter is used.

You can send the output to a remote file location, by piping the display to a remote URL (leading > required). See the copy command for URL syntax.
