Configuring the NTP Time Server and Time Services (QFabric System)

date_range
arrow_backward
arrow_forward

To configure the external time server using the CLI:

  1. Configure the IP address of the external time server.
    content_copy zoom_out_map
    [edit system ntp]
user@switch# set server address

    For example, to set an IP address of 10.1.1.1 for your external time server:

    content_copy zoom_out_map
    user@switch# set server 10.1.1.1
  2. (Optional) Configure the key number to encrypt authentication fields in packets that are sent to the external time server.
    content_copy zoom_out_map
    [edit system ntp]
user@switch# set server address key key-number

    For example, to set a key number of 1:

    content_copy zoom_out_map
    user@switch# set server address key
  3. (Optional) Specify the external time server as a preferred host. Doing this enables the switch to synchronize with the external time server.
    Note:

    The switch can synchronize with the external time server, but the external time server cannot synchronize with the switch.

    content_copy zoom_out_map
    [edit system ntp]
user@switch# set server address prefer
  4. (Optional) Specify the NTP version number to be used in outgoing NTP packets.
    content_copy zoom_out_map
    user@switch# set server address version

    For example, to specify version 3:

    content_copy zoom_out_map
    user@switch# set server address version 3
