Filter in Selected Patterns
Checking this option includes the selected patterns in the trace capture (see Figure 2.42
on page 65 ).
Filter Out Selected Patterns
Checking this option excludes the selected patterns in the trace capture (see Figure 2.42
on page 65 ).
Always Filter Out
Check one or more option to exclude Idles and or P1 through P8 in the trace capture (see
Figure 2.42 on page 65 ).
Note:
Capturing a full buffer requires you to capture the traffic with all ports. Using four ports allows
you to capture only half the system memory. The size of the system memory is based on the
license purchased.
Auto Negotiation
Check this box to always filter out Auto Speed Negotiation traffic. (see Figure 2.42 on
page 65 ).
Truncate Payload
Check this option to truncate payload after x ‐ number of Dword(s) (see Figure 2.42 on
page 65 ).
Note:
For iSCSI packets, payload truncation may not truncate at the specified value as some packets
could come out of sequence.

progresses, the Session Controller indicator changes to reflect the recording progress
graphically:
