Receive Errors
Slot/Conn
Slot location of the Ethernet module within the chassis

Checksum Errors
Number of frames received with a CRC error.
Alignment Errors
Number of frames received that did not contain an
integral number of octets. Normally a frame alignment
error also causes a checksum error on the frame.

Overflow Errors
Number of overflow errors received on this line in which
the device FIFO buffer overflowed before obtaining the
next DMA cycle.

Frames Too Long
Number of frames received that exceed the MTU size.
Symbol Errors
Number of errors in hardware MLT3 encoding. This

other hardware problems.
