Configuring Observer for your Gigabit device
Jumbo Frame Support (Gigabit Ethernet)
rev. 1
Depending on your probe and your network, you may need to make
some changes from the factory defaults.
"Jumbo Frame Support (Gigabit Ethernet)" on page 31
"Configuring Terms of Service and Quality of Service settings"
on page 32
When a Gigabit Ethernet GigaStor is the selected probe, Observer
displays an additional Gigabit tab on the Probe or Device Setup
dialog. This allows you to adjust the maximum frame size. The default
is 1514 bytes (excluding the frame checksum), which is appropriate
for standard Ethernet. If the network link you are analyzing is
configured to support jumbo frames (i.e., frames larger than 1514
bytes) you may want to change this setting to match the frame size of
the Gigabit network, up to a maximum size of 9014 bytes. Observer
will then discard frames that exceed this maximum frame size,
generating a "Frame too large" error.
Select the gigabit probe and right-click. A menu appears. Choose

Probe or Device Settings.
Click the Gigabit tab (Figure 19).
