Root-cause analysis of a wireless LAN

IP 9.1 provides root-cause analysis of wireless LAN for three different deployment scenarios:

• Thin Client Centralized Deployment as listed in Root-cause analysis of a wireless LAN Thin client centralized deployment. Here, the WirelessController is responsible for providing the monitoring data for WirelessAccessPoint and WirelssClient.

  Note:

  In IP, the WirelessController SNMP Agent is used to poll the status of the WirelessAccessPoint and WirelessClient.

• Thin Client Distributed Deployment as listed in Root-cause analysis for thin client distributed deployment. Here, the WirelessController is responsible for providing the monitoring data for WirelessAccessPoint and WirelssClient, for multiple distributed network.

• Thick Client Autonomous Deployment as listed in Root-cause analysis for thick client autonomous deployment. In an autonomous deployment, the WirelessAccessPoint provides the monitoring data for WirelssClient.

  Note:

  In IP, the WirelessAccessPoint SNMP Agent is used to poll the status of the WirelessClient.

  Root-cause analysis of a wireless LAN Thin client centralized deployment lists the root-cause analysis done for thin client centralized deployment.

Table 1. Root-cause analysis of a wireless LAN Thin client centralized deployment

Class	Root-cause	Events (symptoms of root-cause)	Impacted system
WirelessController	Down	WirelessController Unresponsive WirelessController MightBeDown.	WirelessAccessPoint
			WirelessClient
WirelessAccessPoint		Down This event is generated when: The SNMP status of the WirelessAccessPoint is DOWN or NOTPRESENT, and The WirelessController is responsive	WirelessClient
WirelessClient		Disconnected This event is generated when: The WirelessClient is enabled for monitoring, and Host WirelessAccessPoint is responsive	None

Root-cause analysis for thin client distributed deployment lists the root-cause analysis done for a thin client distributed deployment.
