LAG

DynamicCostOff

Table 1. DynamicCostOff properties
Property name	Value
Application name	LAG
Event ID	2002
Event name	DynamicCostOff
SNMP notification prefix and OID	TIMETRA-LAG-MIB.tLagNotifications.2
Default severity	warning
Source stream	main
Message format string	LAG $tLagIndex$ exited dynamic-cost mode
Cause	A sufficient number of ports in the LAG repaired, so the remaining number of operational ports in the LAG was greater than the port threshold.
Effect	The LAG exits dynamic-cost mode; OSPF and other services on the LAG change their cost.
Recovery	No recovery is necessary.

DynamicCostOn

Table 2. DynamicCostOn properties
Property name	Value
Application name	LAG
Event ID	2001
Event name	DynamicCostOn
SNMP notification prefix and OID	TIMETRA-LAG-MIB.tLagNotifications.1
Default severity	warning
Source stream	main
Message format string	LAG $tLagIndex$ entered dynamic-cost mode
Cause	A sufficient number of ports in the LAG failed, so the remaining number of operational ports in the LAG was less than or equal to the port threshold.
Effect	The LAG enters dynamic-cost mode; OSPF and other services on the LAG change their cost.
Recovery	Either repair enough physical ports so that the number of operational ports in the LAG is greater than or equal to the port threshold, change the port threshold, or change the port threshold action from dynamic-cost to down.

LagPortAddFailed

Table 3. LagPortAddFailed properties
Property name	Value
Application name	LAG
Event ID	2003
Event name	LagPortAddFailed
SNMP notification prefix and OID	TIMETRA-LAG-MIB.tLagNotifications.3
Default severity	warning
Source stream	main
Message format string	Could not add port $tmnxPortPortID$ to LAG $tLagIndex$ because $tLagNotifyPortAddFailReason$
Cause	The tLagPortAddFailed notification is generated when a port failed to be added to the lag.
Effect	Dependent upon the value of tLagNotifyPortAddFailReason.
Recovery	Dependent upon the value of tLagNotifyPortAddFailReason.

LagPortAddFailureCleared

Table 4. LagPortAddFailureCleared properties
Property name	Value
Application name	LAG
Event ID	2005
Event name	LagPortAddFailureCleared
SNMP notification prefix and OID	TIMETRA-LAG-MIB.tLagNotifications.5
Default severity	warning
Source stream	main
Message format string	Failure to add port $tmnxPortPortID$ to LAG $tLagIndex$ is resolved - $tLagNotifyPortAddFailReason$
Cause	The failure reported by notification tLagPortAddFailed has been resolved.
Effect	N/A
Recovery	N/A

LagStateEvent

Table 5. LagStateEvent properties
Property name	Value
Application name	LAG
Event ID	2006
Event name	LagStateEvent
SNMP notification prefix and OID	TIMETRA-LAG-MIB.tLagNotifications.6
Default severity	warning
Source stream	main
Message format string	LAG $tLagIndex$ : $tLagNotifyAdditionalInfo$
Cause	The cause described in this event may influence the LAG state.
Effect	The state of the LAG may change.
Recovery	No action needed.

LagSubGroupSelected

Table 6. LagSubGroupSelected properties
Property name	Value
Application name	LAG
Event ID	2004
Event name	LagSubGroupSelected
SNMP notification prefix and OID	TIMETRA-LAG-MIB.tLagNotifications.4
Default severity	warning
Source stream	main
Message format string	$tLagNotifySubGroupSelected$
Cause	The tLagSubGroupSelected notification is generated when the selection algorithm selects a different sub-group.
Effect	No effect.
Recovery	No recovery is necessary.

tLagAdaptiveLoadbalancingChanged

Table 7. tLagAdaptiveLoadbalancingChanged properties
Property name	Value
Application name	LAG
Event ID	2009
Event name	tLagAdaptiveLoadbalancingChanged
SNMP notification prefix and OID	TIMETRA-LAG-MIB.tLagNotifications.9
Default severity	warning
Source stream	main
Message format string	LAG $tLagIndex$ adaptive load balancing changed - $tLagNotifyAdditionalInfo$
Cause	The tLagAdaptiveLoadbalancingChanged is sent when the re-balancing algorithm modifies the LAG hash bucket allocation.
Effect	A better loadbalancing of the egress traffic on the active lag members.
Recovery	No special recovery action is necessary.

tLagMemberStateEvent

Table 8. tLagMemberStateEvent properties
Property name	Value
Application name	LAG
Event ID	2007
Event name	tLagMemberStateEvent
SNMP notification prefix and OID	TIMETRA-LAG-MIB.tLagNotifications.7
Default severity	warning
Source stream	main
Message format string	LAG $tLagIndex$ : $tLagNotifyAdditionalInfo$
Cause	The cause described in this event may influence the LAG state.
Effect	The state of the LAG may change.
Recovery	No action needed.

tmnxLagBfdMemStateChanged

Table 9. tmnxLagBfdMemStateChanged properties
Property name	Value
Application name	LAG
Event ID	2008
Event name	tmnxLagBfdMemStateChanged
SNMP notification prefix and OID	TIMETRA-LAG-MIB.tLagNotifications.8
Default severity	minor
Source stream	main
Message format string	LAG $tLagIndex$ member $tmnxPortPortID$ BFD state changed to $tmnxLagBfdMemState$ - $tLagNotifyAdditionalInfo$
Cause	The tmnxLagBfdMemStateChanged notification is sent when the value of an instance of the object tmnxLagBfdMemState changes. The cause is explained in the tLagNotifyAdditionalInfo.
Effect	While the value of the object tmnxLagBfdMemState is equal to - 'idle', 'failed', 'waitingFwd', 'up': the port is forwarding traffic; - 'waiting', 'down': the port is not forwarding traffic.
Recovery	The recovery action will depend on the actual cause as specified in the tLagNotifyAdditionalInfo.
