Configuring NTP on the Router
The following sections describe information you supply and options you select
that affect the way NTP runs on the router.
Enabling and Disabling NTP
After you create NTP on the router, as described in Chapter 1, default values are
in effect for all NTP parameters (see parameter descriptions in Appendix A). You
may want to change these values, depending on the requirements of your network.
Setting NTP Client Mode
There are three modes in which you can configure NTP: Unicast Client, Broadcast
Client, and Multicast Client. By default, NTP runs in Unicast Client mode.
Currently, Bay Networks supports only Client mode.
You select Unicast Client mode when you want to configure peers. You select
Broadcast Client mode and Multicast Client mode when you want to configure
access control filters to restrict certain peers from becoming time servers for an
NTP client.
Configuring Time Servers on a Router
You can configure time servers (peers) for time synchronization in Unicast Client
mode only. Configuring a time server involves
• Adding time servers
• Specifying the configuration peer mode for the time server
• Setting the mode of operation of the router
• Specifying a source IP address
• Specifying peer preference
• Deleting peers
