Monitoring and Troubleshooting a
Wired LAN
After you connect the instrument to your network and
power it on, the instrument attempts to become an
active device on the network by obtaining an IP address.
By default, it tries to acquire an address by using DHCP.
Note
If your network policy requires the use of fixed
IP addresses or if you need to change other
network configuration data (such as the default
router), see “Configuring the Instrument for a
Wired LAN” on page 74.
If the instrument acquires a valid IP address, it
automatically runs a series of tests that include verifying
the cable and signal, gathering network utilization and
bandwidth statistics, and actively discovering networks,
services, and devices using the network. It reports its
findings on the Test Results screen.
If the instrument cannot acquire a valid IP address, it can
still analyze traffic for statistics and passively discover
devices. However, without a valid IP address, the
instrument cannot run its active discovery tests. The basic
steps for monitoring and troubleshooting a wired LAN
are given below. Detailed information for a step can be
obtained by going to the referenced section provided at
each step:
1.
Power on the instrument (see “Turning the
Instrument On and Off” on page 14) and, if
necessary, configure the interface type (see
“Selecting the LAN or WLAN Interface” on page 15).
