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 Remote Annex accepts the

 

first response it receives and drops all others.

 

Dropped packets are normal.
