Packet Status Flags in the Summary Pane
Displaying Captured Data
For most network topologies, the Status column in the Summary pane
is empty if the packet is normal with no errors, symptoms, or diagnoses
associated with it. The exceptions to this rule are as follows:
For data captured from a wireless LAN, the Status column
indicates the wireless LAN channel from which the packet was
captured inside brackets. For example, an entry of [1] in the
Status column indicates that the corresponding packet was
captured from wireless LAN channel number 1.
Otherwise, Table 8-8 lists the flags used in the Status column of the
Summary pane. Note that any of the flags associated with error frames
(CRC, Jabber, Runt, and so on) require an enhanced driver for detection
and reporting.
Table 8-8. Status Flags
M Packet is marked. Mark a packet to return quickly to a

Trigger Packet is an event filter trigger
CRC CRC error packet with normal packet size

Fragment Packet size is less than 64 bytes (including the 4 CRC
bytes) with CRC error
