Configuring DNS
You can configure the WSS to resolve hostnames to their IP addresses by querying a Domain Name Service (DNS)
server. By enabling DNS, you can specify a hostname rather than an IP address. For example, rather than typing telnet
10.1.2.3, you could type telnet monterey.example.com. By default, DNS is not enabled. You can specify one primary
DNS server and up to five secondary DNS servers.
server. By enabling DNS, you can specify a hostname rather than an IP address. For example, rather than typing telnet
10.1.2.3, you could type telnet monterey.example.com. By default, DNS is not enabled. You can specify one primary
DNS server and up to five secondary DNS servers.
You configure DNS by performing the following tasks:
•
Enable the DNS client and configure a default domain name for DNS queries.
•
Specify the IP addresses of the DNS servers.
To enable DNS and create a DNS server:
1
Access the Create DNS Server wizard:
a
a
Select the Configuration tool bar option.
b
In the Organizer panel, click the plus sign next to the WSS.
c
Click the plus sign next to System.
d
Select IP Services.
e
In the Task List panel, select DNS Server.
2
Type the server address in the IP Address box.
3
Select whether the server is primary or secondary.
You can designate only one DNS server as the primary DNS server. All other DNS servers are secondary
servers.
servers.
4
Click OK.
5
In the Default DNS Domain box, type the default domain suffix that is appended to a hostname if the
hostname cannot be resolved as entered. The suffix can be up to 64 characters long with no spaces or tabs.

Configuring NTP
You can configure a WSS 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.

Note.
If NTP is configured on a system whose current time differs from the NTP server
time by more than 10 minutes, convergence of the WSS time can take many NTP update
intervals. Nortel recommends that you set the time manually to the NTP server time before
enabling NTP to avoid a significant delay in convergence.
