717User Manual 1175.6632.02 ─ 16
By default, the R&S SMW is configured to use dynamic TCP/IP configuration and to
obtain the whole address information automatically.
If the network does not support DHCP or the attempt does not succeed, the instrument
tries to obtain the IP address via Zeroconf (APIPA) protocol. IP addresses assigned via
Zeroconf start with the number blocks 169.254.*.*.
Note: An IP address that is assigned via the Zeroconf protocol although the network
requires an IP address assigned via the DHCP server can cause network connection
failures.
See Chapter 15.5, "Resolving Network Connection Failures", on page 1177.
To assign the IP address manually, select Address Mode > "Static".
Remote command:
:SYSTem:COMMunicate:NETWork:IPADdress on page 1125
Subnet Mask
Displays the bit group of the subnet in the host identifier.
To assign the subnet mask manually, select Address Mode > "Static".
Remote command:
:SYSTem:COMMunicate:NETWork[:IPADdress]:SUBNet:MASK on page 1127
Default Gateway
Displays the gateway address.
This address identifies the router on the same network as the instrument that is used to
forward traffic to destinations beyond the local network.
To assign the gateway address manually, select Address Mode > "Static".
Remote command:
:SYSTem:COMMunicate:NETWork[:IPADdress]:GATeway on page 1127
DNS Suffix
Displays the primary DNS (Domain Name System) suffix, that means the DNS name
without the hostname part.
The DNS system uses the suffix for registration and name resolution for unique identifi-
cation of the instrument in the entire network.
To assign the DNS suffix manually, select Address Mode > "Static".
Remote command:
:SYSTem:COMMunicate:NETWork[:COMMon]:DOMain on page 1126
DNS Server
Determines the preferred server for name resolution. The DNS server contains the
underlying numerical values that are required for name resolution of the hostname as
part of the IP address.
To select the DNS server manually, select Address Mode > "Static".
Remote command:
:SYSTem:COMMunicate:NETWork[:IPADdress]:DNS on page 1127
