Adding DNS Servers
To add a DNS server:
1 Do one of the following:
 Open the WX Switch wizard, then select DNS under IP Services in the
organizer list of the System and Administrative page.
 In the Organizer panel, select IP Services under a WX switch, then
select Config > Edit. The Modify IP Services wizard appears. Click on
DNS at the top of the wizard.
2 Click on a row in the IP Address column.
3 Change the IP address in the row to the address of the DNS server.
4 If this server is the primary DNS server for the switch, select the checkbox
in the Primary column.
5 You can designate only one DNS server as the primary DNS server. All
other DNS servers are secondary servers.
6 To add more DNS servers, repeat step 1 through step 4 for every server.
You can add a total of six DNS servers.
7 Do one of the following:
 Go to “Configuring NTP”.
 Select another item in the WX Switch wizard, if you are using this
wizard.
 Click Finish to close the wizard and save changes.
Configuring NTP You can configure a WX switch to use the Network Time Protocol (NTP)
to automatically set the system date and time. NTP polls network time
servers at regular intervals and synchronizes the system date and time
with the servers. By default, NTP is not enabled. You can specify up to
three NTP servers.
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.
