Configuring Observer for your Gigabit device

Depending on your probe and your network, you may need to make some changes from the factory defaults.

Jumbo Frame Support (Gigabit Ethernet)

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.

1Select the gigabit probe and right-click. A menu appears. Choose Probe or Device Settings.

2Click the Gigabit tab (Figure 19).

3Change the frame size to suit your needs and click OK.
