| Port in the VLAN is having HighUtilization event active and carries MDM/SDS traffic. Note: Port HighUtilizationActive is one of the performance event, similarly all the port performance events like HighErrorRate,HighDiscardRate,HighBroadcastRate, HighCollisionRate,HighQueueDropRate are also covered part of RCA scenario. These Ports performance events will be the RCA event. |
