tion indicating that number of active 
sessions on the system exceeded system sessions 
threshold value. System sessions threshold value 
is indicated by cPppoeSystemThresholdSessions. 
          
An  agent  must  not  generate  more  than  one
cPppoeSessionThresholdTrap `trap-event` in a
30 second period,  where a  `trap-event` is  the
transmission of a single trap  PDU to a  list of
trap destinations. If additional `the number of
PPPoE  sessions  exceeds  threshold`  condition
occur within the 30  second `throttling` period,
then these  trap-events should be suppressed by
the agent. An NMS should periodically check the
value of  cPppoeCurrSessions to  detect  any
missed cPppoeVcSessionThresholdTrap trap-events,

fluctuating around the watermark during 30 seconds, then 
these  trap-events should be suppressed by agent.

trap destinations. If additional `the number of 
PPPoE  MAC sessions  exceeds the allowed limit`  condition 
occur within the 30  second `throttling` period,

the agent.

tion indicating that the number of new PPPoE 
session requests coming in over a configured time 
interval, from a particular client Ethernet MAC address,
has crossed rate limit cPppoeSystemPerMacThrottleRatelimit.

a Vlan has reached the maximum limit. There won't be any 
new PPPoE session possible on this Vlan. The maximum limit

The Vlan ID of vlan can be referred though object 
cPppoeSystemSessionVlanID. If Vlan is QinQ, 
cPppoeSystemSessionInnerVlanID refers the 
inner Vlan id. In case the vlan is not QinQ

An agent should generate single 
cPppoeSystemSessionPerVLANThrottleNotif trap for the
