Status Code Definitions
Code Description
A Alignment errors.
C CRC error with valid packet sizes.
D Data integrity. Captures frames with payload errors. Data Integrity controls
payload integrity. (Both SmartMetrics Sequence & Latency test as well as Capture
can detect and record a data integrity error event).
FIPframe.
I Subminimum interframe gap (gap is lower than the allowable gap for the physical
medium).
K IP checksum. Captures the frames with incorrect IP Checksum.
L Collision/collided.
O Oversize packet (greater than 1518 bytes or 1522 bytes with VLAN tag) or
oversized (jabber) frame.
PPause.
R For L3-6705/L3-6710: Receive overrun. Received packet is too large for buffer
and packet is truncated to fit buffer.
For GX-1405: Running Disparity Errors. Disparity errors occur when the
positive or negative disparity between two code groups (in the Gigabit 8B/10B
transmission code) is incorrect. Disparity errors may indicate an encoding or line
problem; excessive errors may cause the link to fail.
S Packet contains a SmartMetrics signature field (Layer 3).
T Packet met trigger criteria. Captures frames with receive triggers defined in the
Trigger Setup window.
U Undersize packet or (runt) frame, less than 64 bytes.
V Packet contains a VLAN tag (for ML-7710 only).
