B-27

3. Specify the number of bytes after the Reference with which to begin the

comparison:

set wfPktCaptureEntry.15.102101 12

represents the wfPktCaptureRxFltr1Offset attribute.

4. Specify the number of bytes in the packet to compare with the string:

set wfPktCaptureEntry.17.102101 2

represents the wfPktCaptureRxFltr1Size attribute.

5. Specify the string as the hexadecimal number 0800:

set wfPktCaptureEntry.18.102101 0x0800;commit

represents the wfPktCaptureRxFltr1Match attribute.

Example 5

This example speciﬁes that Packet Capture copy only incoming packets with both

a Type ﬁeld of hexadecimal 0800 and a destination MAC address of ffffffffffff. It

assumes you already speciﬁed the Type ﬁeld as shown in Example 4

. The

instructions are as follows:

1. Copy incoming packets that match the Receive Filter 2 Match parameter

setting:

set wfPktCaptureEntry.24.102101 1

represents the wfPktCaptureRxFltr2Type attribute.

2. Specify the Reference with which to begin the comparison:

set wfPktCaptureEntry.26.102101 1

represents the wfPktCaptureRxFltr2Ref attribute.

3. Specify the number of bytes after the Reference with which to begin the

comparison:

set wfPktCaptureEntry.25.102101 0

represents the wfPktCaptureRxFltr2Offset attribute.

4. Specify the number of bytes in the packet to compare with the string:

set wfPktCaptureEntry.27.102101 6

represents the wfPktCaptureRxFltr2Size attribute.
