Configuring the domain name system (DNS)
The domain name system (DNS) lets you type a domain name in the address bar to connect to the
instrument. If you use DNS, you can use a name instead of an IP address.
Example:
Model2657A.XYZcompany.com
Contact your corporate information technology (IT) department to learn more about DNS. If a DNS
server is not part of the LAN infrastructure, this setting is not used.
To enable or disable DNS host name verification:
1. From the front panel, press the
MENU
key, and then select
LAN > CONFIG > DNS > VERIFY
.
2. Turn the navigation wheel
to select either
ENABLE
or
DISABLE
. When enabled, the
instrument performs a DNS lookup to verify the DNS host name matches the value specified in
the
(on page 7-111) attribute.
3. Press
the
ENTER
key.
4. Press
the
EXIT (LOCAL)
key twice to return to the LAN CONFIG menu.
5. Select
APPLY_SETTINGS > YES
, and then press the
ENTER
key.
To enable or disable DNS registration:
1. From the front panel, press the
MENU
key and select
LAN > CONFIG > DNS > DYNAMIC
.
2. Turn the navigation wheel
to select either
ENABLE
or
DISABLE
. DNS registration works with
the DHCP to register the host name specified in the
lan.config.dns.hostname
attribute with
the DNS server.
3. Press
the
ENTER
key.
4. Press
the
EXIT (LOCAL)
key twice to return to the LAN CONFIG menu.
5. Select
APPLY_SETTINGS > YES
, and then press the
ENTER
key.
To set the DNS server IP addresses:
1. From the front panel, press the
MENU
key and select
LAN > CONFIG > DNS
.
2. Turn the navigation wheel
to select either
DNS-ADDRESS1
or
DNS-ADDRESS2
.
3. Press the
ENTER
key.
4. Turn the navigation wheel
to select and enter a valid IP address for the DNS server.
5. Press the
ENTER
key.
6. Press the
EXIT (LOCAL)
key twice to return to the LAN CONFIG menu.
7. Select
APPLY_SETTINGS > YES
, and then press the
ENTER
key.
LAN speeds
Another characteristic of the LAN is speed. The Model 2657A negotiates with the host computer and
other LXI-compliant devices on the LAN to transmit data at the highest speed possible. LAN speeds
must be configured to match the speed of the other instruments on the network.
