ntp

Displays Network Time Protocol (NTP) information. NTP enables clock synchronization within a network.

Supported on the following devices:

Syntax

show ntp [associations|status]
show ntp [associations {detail|on}|status {on <DEVICE-NAME>}]

Parameters

show ntp [associations {detail|on}|status {on <DEVICE-NAME>}]
ntp associations {detail|on} Displays existing NTP associations. The interaction between the controller or service platform and a SNTP server constitutes an association. SNTP associations are of two kinds:
  • peer associations - where a controller or service platform synchronizes to another system or allows another system to synchronize to it, or
  • - server associations - where only the controller or service platform synchronizes to the SNTP resource, not the other way around.
Specify the following parameters to view NTP association details:
  • detail – Optional. Displays detailed NTP associations
    • on <DEVICE-NAME> – Optional. Displays NTP associations on a specified device
      • <DEVICE-NAME> – Specify the name of the AP, wireless controller, or service platform.
Note: If the ‘on‘ keyword is used without the ‘detail‘ keyword, the system displays a summary of existing NTP associations on the specified device or RF Domain.
ntp status {on <DEVICE-NAME>} Displays the performance (status) information relative to the NTP association status. Use this command to view the access point, controller, or service platform‘s current NTP resource.
  • on <DEVICE-NAME> – Optional. Displays NTP association status on a specified device
    • <DEVICE-NAME> – Specify the name of the AP, wireless controller, or service platform
