Table 47 describes the interface counters that System Monitor monitors on external interfaces.

CRC Align Errors

The total number of frames received that had a

No

length (excluding framing bits but including Frame

 

Buffer 0

 

 

Check Sequence (FCS) octets) of from 64 through

 

High 300

 

 

1518 octets. The error indicates either a bad FCS

 

 

 

 

with an integral number of octets (an FCS error) or a

 

 

 

 

bad FCS with a non-integral number of octets (an

 

 

 

 

Alignment error).

 

 

 

 

 

 

RX Symbol Error

The interface detects an undefined (invalid) symbol

No

Low 0

 

 

received. Large symbol errors indicate a bad device,

 

Buffer 0

 

 

cable, or hardware.

 

High 5

 

 

 

 

RX IFG Violated

A minimum-length interframe gap (IFG) between

Yes

Low 5

 

 

successive frames is violated. A typical IFG is 12

 

Buffer 0

 

 

bytes.

 

High 100

 

 

 

 

RX Missing Termination

The number of frames that terminated by anything

No

Low 12

Characters

 

other than the Terminate character; this includes

 

Buffer 0

 

 

termination due to the Error character.

 

High 300

NOTE

The default settings for the above high threshold, above low threshold, below high threshold, and below low threshold actions are None.
