. Network Statistics
Statistic
Description
Frames Received
The number of frames received.
CRC Errors
The number of CRC checksum errors detected.
Alignment Errors
The number of frames received misaligned with a CRC
error.
Resource Drops
The number of packets dropped because the ROM
code could not buffer them quickly enough. The ROM
code cannot always handle back-to-back incoming
packets. The Micro-CS accepts the first response it
receives and drops all others. Dropped packets are
normal.
Bus Wait Drops
The number of packets dropped due to waiting too
long for a bus to become available.
Bad Types/
Lengths
The number of unknown packet types if Ethernet IP
encapsulation is being used. The number of packets
with illegal lengths if IEEE 802.2/802.3 IP
encapsulation is being used.
Frames Sent
The number of frames sent.
Carrier Sense
Losses
The number of times packets could not be transmitted
because the Micro-CS lost the Carrier Sense signal –
usually the result of excessive traffic on the Ethernet.
