Sending 5 ICMP echos to 172.16.5.1, timeout = 2 sec.
.....
Success rate = 100% (0/5), round-trip min/avg/max = 0/0/0 ms
host1:boston#configure terminal
host1:boston(config)#ntp server 172.16.5.1
host1:boston(config)#ntp enable
NTP communications are established on the virtual router boston. The system is specified
as an NTP server.
host1#virtual-router boston
host1:boston#configure terminal
host1:boston(config)#ntp server
NTP communications are established on the virtual router boston. The router is specified
as an NTP broadcast server and synchronizes with NTP server 172.16.5.1. The specified
interface enabled for NTP broadcasting is configured with version 4 and poll interval 5
for broadcasting NTP messages.
host1#virtual-router boston
host1:boston#configure terminal
host1:boston#ntp enable
host1:boston(config)#ntp server 172.16.5.1
host1:boston(config)#interface fastethernet 9/3
host1:boston(config-if)#ntp broadcast 4 5
NOTE: In Example 3, the router that acts as the NTP broadcast server must
either synchronize to another server or master (specified by the ntp server
command) or act as master (ntp master command).
After you configure the system as an NTP client, you can use show commands to view
information about the NTP servers you assigned and the status of NTP on the interface.
NOTE: For about 30 minutes after you configure the system as an NTP client,
the data varies rapidly, and then starts to stabilize. Wait at least 1 hour before
using the data to make decisions about NTP servers.
Many of the fields in the displays of these show commands take their values from the
NTP messages. The NTP client uses this data to compare the performance of its NTP
servers and to choose a master.
Use to view the information about the NTP servers you assigned.
