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:

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
