128 CHAPTER 6: CONFIGURING AND MANAGING IP INTERFACES AND SERVICES
MSS adjusts the NTP reply according to the following time parameters
configured on the WX switch:
Offset from UTC (configured with the timezone command; see
“Setting the Time Zone” on page 125)
Daylight savings time (configured with the set summertime
command; see “Configuring the Summertime Period” on page 125)
The NTP client is disabled by default.
If NTP is configured on a system whose current time differs from the NTP
server time by more than 10 minutes, convergence of the WX time can
take many NTP update intervals. 3Com recommends that you set the
time manually to the NTP server time before enabling NTP to avoid a
significant delay in convergence.
Adding an NTP Server To add an NTP server to the list of NTP servers, use the following
command:
set ntp server ip-addr
To configure a WX switch to use NTP server 192.168.1.5, type the
following command:
WX1200# set ntp server 192.168.1.5
Removing an NTP
Server
To remove an NTP server, use the following command:
clear ntp server {ip-addr | all}
If you use the all option, MSS clears all NTP servers configured on the
switch.
Changing the NTP
Update Interval
The default update interval is 64 seconds. To change the update interval,
use the following command:
set ntp update-interval seconds
You can specify an interval from 16 through 1024 seconds.
For example, to change the NTP update interval to 128 seconds, type the
following command:
WX1200# set ntp update-interval 128
success: change accepted.
