Floating License

Note:

If traffic is balanced on ports, sample size is the same whether you check or uncheck the

Sampling Memory Usage Optimization option.

Note:

Memory Assignment depends on traffic load distribution at the time when the system tries to

re‐assign physical links to memory banks. Therefore, if you repeat a capture with the same
Sampling Memory Size and Segment Number parameters, the resulting sample size may not be
the same. However, if traffic load distribution is similar, sample size will be similar.

Note:

The buffer status indicator shows buffer by FPGA, not by port.

If the Sampling Memory Usage Optimization Option is Not Checked

Each physical link (or logical link if MUX is enabled) is assigned to a specific memory space
(memory bank), depending on the Sampling Memory Size and Segment Number
parameters.

Important: If any physical link fills its memory bank, the recording process stops. Other
memory banks will typically be less than full (and can be empty). The sample file might be
smaller than the user‐defined Sampling Memory Size. You might even think that the
Analyzer malfunctioned.

License

Note:

License Manager is only available when in Cascading mode. For example, if one unit is licensed

only for JJJJ and a second unit is licensed only for AAAA, cascading the two units and using the
License Manager allows each unit to do JJAA.

To manage the license, select Setup > Manage Setup Licenses.

The Floating License dialog (see

Figure 3.135 on page 314

) displays the available

functionality by Function, Total Ports, Assigned To ports, and Not Used. It also displays the
Current License Configuration by License Type, Serial Number, Analyzer, Device Emulator,
Host Emulator, and InFusion.
