TCP/IP Settings
If DHCP is available, the Instrument Settings—TCP/IP screen
(Instrument Settings—TCP/IP Screen) displays the address
that the instrument is able to obtain.
If you want to manually configure the IP address or change
the subnet mask, do the following:
Note
When manually assigning an IP address, you can use
an address for an alternate subnet but that address
must be in the same broadcast domain as the
EtherScope Network Assistant.
1
Clear the Automatically configure TCP/IP settings
checkbox to disable auto-configuration of the IP
settings.
2
For the address field that you want to change, do the
following:
•
Tap and use the keyboard to type an IP address.
OR
•
Select an address from the drop-down list.
3
Tap to save your changes.
802.1Q/IP TOS Settings
The 802.1Q/IP TOS settings define the VLAN tag in the
header of an Ethernet packet. The instrument uses these
settings during discovery, traffic generation, RFC 2544 tests,
and network service tests to make decisions about routing
traffic.
In the preview pane, tap 802.1Q/IP TOS to display the
Instrument Settings— 802.1Q/IP TOS screen. This screen
enables you to configure the instrument for tagged VLAN
(802.1Q) and/or IP Type of Service (TOS) operation. These
settings are applied globally to traffic from the instrument
and remain in memory even after you turn off the
instrument.
