Configuring NTP Broadcast Mode on a C Series Controller (SRC CLI)

Use the following configuration statements to configure NTP on a C Series Controller to operate in broadcast mode:

system ntp broadcast address {ttl ttl ; version version ; }

To configure NTP to operate in broadcast mode:

  1. From configuration mode, access the configuration statement that configures NTP broadcast, and specify the broadcast address on one of the local networks or a multicast address assigned to NTP. You can specify an IP address or a hostname.

    We recommend that you use the multicast address 224.0.1.1 because the Internet Assigned Numbers Authority (IANA) assigns this address for NTP; however, you can use a different address for local deployments.

    [edit system ntp]user@host# edit broadcast address

    For example, to specify the broadcast address of 244.0.1.1:

    [edit system ntp]user@host# edit broadcast 224.0.1.1 [edit system ntp broadcast 224.0.1.1]user@host#
  2. (Optional) Specify the version of NTP to be used for outgoing packets.
    [edit system ntp broadcast address ]user@host# set version version
  3. (Optional) Specify the time-to-live value to transmit.
    [edit system ntp server address ]user@host# set ttl ttl
