Ntp-Service Unicast-Server - 3Com 7750 Series Command Reference Manual

3Com Switch 7750 Series
Command Reference Guide – NTP
Description
Use the ntp-service unicast-peer command to configure NTP peer mode.
Use the undo ntp-service unicast-peer command to cancel NTP peer mode.
By default, no NTP peer mode is configured. When you do not specify a version
number,
authentication-keyid, authentication is disabled and the local server is not the first
choice.
This command sets the remote server at ip-address as a peer of the local device,
which operates in symmetric active mode. ip-address specifies a host address other
than a broadcast address, multicast address, or the IP address of a reference clock.
Under this configuration, a local device can synchronize and be synchronized by a
remote server.
Example
# Configure the local device to synchronize or to be synchronized by a peer at
128.108.22.44. Set the NTP version to 3. The IP address of the NTP packets is taken
from that of VLAN-interface 1.
