Interface error types

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

TABLE 47	Interface errors monitored by System Monitor
Interface error		Description	Port Fence	Threshold
			support	defaults
CRC Align Errors		The total number of frames received that had a	No	Low 12
		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.
