Rcv Port Usage exceeded Tn Cn | Cabletron Systems 1800 instruction

Meaning:	The port statistic Receive Error Ratio has exceeded the threshold
	(T:“n” ) that was set by the user. (C:“n” is the current value.) The
	Receive Error Ratio is the ratio of frames rejected per second to
	frames accepted per second.
Action:	If this happens frequently, check the line for noise, and check for
	configuration errors on both the port and the connected device.

318.Rcv Port Usage exceeded T:“n” C:“n”

Severity:	4
Meaning:	The port statistic % Receive Port Util (Utilization) has exceeded the
	threshold (T:“n” ) that was set by the user. (C:“n” is the current
	value.) Percent of Receive Port utilization is the ratio of non-flag
	characters to total characters being received by the port.
Action:	If this happens frequently, you may need to add ports or reroute
	some traffic.

319.Trn Port Usage exceeded T:“n” C:“n”

Severity:	4
Meaning:	The port statistic % Transmit Port Util (Utilization) has exceeded the
	threshold (T:“n” ) that was set by the user. (C:“n” is the current
	value.) Percent of Transmit Port Utilization is the ratio of non-flag
	characters to total characters being received by the port.
Action:	If this happens frequently, you may need to add ports or reroute
	some traffic.

400.Link Enabled

Severity: 2

Meaning: The port has been enabled from the On-Line Port Operations Menu.

Action: None.

401.Link Disabled

Severity: 2

Meaning: The port has been disabled from the On-Line Port Operations Menu.

Action: None.

402.Link Disconnected

Severity: 2

Meaning: For frame relay or X.25, this means that the link is disconnected and level 2 cannot be established.

For SNA TPAD, this means that an XID command frame has been issued by the TPAD, but either there has been no response or the received XID data does not match the XID data configured for the TPAD subscriber. For SNA HPAD, this means that no XID or SNRM command frame has been received for any link address con- figured for the HPAD subscriber.
