4.11 Set up Capture Packet Format
Please note that XM-23L4, XM-23L4G and XM-28L1 do not support this function.
Each port has an extensive buffer (XM-2301: 512 frames, XM-22R4(F): 8MB, XM-
23R2(G): 63MB); t his buffer may be used to capture the data “raw” as it is received.
Data recorded into the capture buffer is triggered by a set of conditions. Packets are
filtered as well. During capture mode operation, the amount of data per packet can be
limited.
When defining a trigger pattern, the receiving card captures all packets that contain the
trigger pattern and ignores all packets that do not contain it. Trigger can also be set for
counters to display the QoS testing results. Users can fill in four sets of data for packet
filtering.
