Ntp-service multicast-server, Parameter, Example | 3Com 10014302

3Com Router Command Reference Guide Addendum for V1.2

Parameter

X.X.X.X: Multicast IP address, that is, Class D address.

Description

Using the ntp-servicemulticast-clientcommand, you can enable the NTP multicast client mode. Using the undo ntp-servicemulticast-clientcommand, you can disable the NTP multicast client mode.

By default, multicast client service is not configured and X.X.X.X is 224.0.1.1.

With this command, you can specify the current interface on the local device to receive NTP multicast messages and the local device to work in multicast-client mode. The local router first detects the multicast message packets from the server. Upon the receipt of the first broadcast message packet, the local router enters a temporary Client/Server mode to exchange the message with the remote server for the purpose of estimating the network delay, and then it switches to the broadcast client mode to assume the work of detecting the incoming multicast message packets with which it can synchronize the local clock.

Example

Receive NTP multicast messages on the interface Ethernet 0, given the multicast group address associated to the multicast messages is 224.0.1.1.
