A3COM0437-SMART-AUTO DEFINITIONS ::= BEGIN

-- This MIB defines control mechanisms for the 3Com proprietary Smart
-- Autosensing feature. The MIB is designed to be equally applicable to 
-- repeaters and switches.

smartAutosensingControl OBJECT-TYPE
	SYNTAX	INTEGER {
		enable (1),
		disable (2),
		restart (3)
	}
	ACCESS	read-write
	STATUS	mandatory
	DESCRIPTION
	"This object enables, disables and restarts the Smart Autosensing
	feature. This feature monitors the cable quality of links and 
	automatically switches the link to a lower speed if a defined cable 
	quality threshold is breached. The feature is reliant on the presence of 
	auto-negotiation on both the managed device and the end station. 
	If the end station only supports a fixed speed of operation the feature 
	will not operate on that interface. This will also be the case if 
	auto-negotiation is switched off for a particular interface on the 
	managed device. The feature is operated on a per stack basis. 
	The enable option will create an RMON alarm on all applicable
	interfaces and start monitoring the smartAutosensingValue. The
	disable option will destroy the RMON alarms on all applicable
	interfaces. The restart option is only available if the current value of 
	smartAutosensingStatus is enabled. The option forces all
	end stations back to their higher speed of operation and begins
	monitoring link quality afresh."

smartAutosensingTable OBJECT-TYPE
	SYNTAX	SEQUENCE OF SmartAutosensingEntry
	ACCESS	not-accessible
	STATUS	mandatory
	DESCRIPTION
	"A list of smartAutosensing entries containing the status of
	the feature and the value of the variable monitored."
::= {smartAutosensing 2}


smartAutosensingEntry OBJECT-TYPE
	SYNTAX	SmartAutosensingEntry
	ACCESS	not-accessible
	STATUS	mandatory
	DESCRIPTION	
	"A smartAutosensing entry containing the status of the 
	interface and the current value of the variable monitored."
	INDEX {ifMauIfIndex, ifMauIndex}
::= {smartAutosensingTable 1}

SmartAutosensingEntry ::= SEQUENCE {
	smartAutosensingStatus		INTEGER,
	smartAutosensingValue		Counter
	}

smartAutosensingStatus OBJECT-TYPE
	SYNTAX	INTEGER {
		notInService(1),
		active(2),
		downrated(3)
	}
	ACCESS	read-only
	STATUS	mandatory
	DESCRIPTION
	"This object shows the status of the Smart Autosensing feature
	on a per interface basis. A status of notInService indicates that either
	the feature is disabled on a per stack basis or that the feature
	cannot be activated on the particular interface. A status of active
	indicates the feature is active but that the cable quality is such that
	no downrating in operating speed has occurred. A status of downrated
	indicates that the interface has moved from a higher operating speed to
	a lower operating speed due to the Smart Autosensing feature. The 
	higher operating speed will not be resumed until loss of link is seen
	or the Smart Autosensing feature is restarted."
::= {smartAutosensingEntry 1}

smartAutosensingValue OBJECT-TYPE
	SYNTAX	Counter
	ACCESS	read-only
	STATUS	mandatory
	DESCRIPTION
	"The value of the variable monitored by the Smart Autosensing
	feature. This could just be a copy of another MIB variable, or more 
	likely a composite of several MIB variables. If the Smart Autosensing
	feature is not active on an interface, this variable will be the value at 
	the time the feature was last active. If the feature has not been active 
	since power on or reset then this variable should have a value of 0."

-- This section defines the trap sent used by the Smart Autosensing feature. 

smartAutosensingActivated TRAP-TYPE
	ENTERPRISE a3Com
	VARIABLES {ifDescr, ifMauIfIndex, ifMauIndex, ifSpeed }
	DESCRIPTION
	"This trap is sent when an interface downgrades from a higher to a lower
	speed due to activation of the Smart Autosensing feature. The variables 
	are the two indices that uniquely identify the interface, the ifDescr of the 
	Mau changing speed and the new speed it will be operating at. On seeing 
	this trap the operator should check the quality of the cable, including any
	patch leads connected to the interface."
