Configuring The Local Clock As A Reference Source - 3Com S7906E Configuration Manual

Configuring the multicast server
To do...
Enter system view
Enter interface view
Configure the device to work in
the NTP multicast server mode
A multicast server can synchronize broadcast clients only after its clock has been synchronized.
You can configure up to 254 multicast clients, among which 128 can take effect at the same time.

Configuring the Local Clock as a Reference Source

A network device can get its clock synchronized in one of the following two ways:
Synchronized to the local clock, which works as the reference source.
Synchronized to another device on the network in any of the four NTP operation modes previously
described.
If you configure two synchronization modes, the device will choose the optimal clock as the reference
source.
Follow these steps to configure the local clock as a reference source:
To do...
Enter system view
Configure the local clock as a
reference source
Use the command...
system-view
interface interface-type
interface-number
ntp-service multicast-server
[ ip-address ]
[ authentication-keyid keyid |
