128CHAPTER 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

Removing an NTP Server

Changing the NTP Update Interval

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

To remove an NTP server, use the following command:

clear ntp server {ip-addrall}

If you use the all option, MSS clears all NTP servers configured on the switch.

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.
