CCNP Enterprise 300-430 Release Date

During the Extensible Authentication Protocol (EAP) process, the RADIUS server generates an encrypted session key after the client’s identity is authenticated. This session key is sent to the access point to encrypt data frames between the client and the access point. It ensures that each session has a unique encryption key, enhancing security. References: Look for information on EAP and RADIUS in the CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

 To ensure the 1810 OEAP can join the controller from remote teleworker locations, the firewall must allow specific UDP ports that are used for AP communication with the controller. UDP ports 5246 and 5247 are used for Control and Provisioning of Wireless Access Points (CAPWAP) control and data messages, while UDP ports 12222 and 12223 are used for OfficeExtend APs’ data traffic. Blocking these ports would prevent the APs from joining the controller, hence they must be allowed on the firewall.

 The exhibit provided appears to be a floor map overlay with Cisco CleanAir Zone of Impact for interferers, which shows different areas affected by interference on a wireless network. The area labeled ‘A’ indicates the greatest impact on the wireless network due to its larger size compared with other zones, suggesting more significant interference or a stronger source of interference within this zone. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

The issue with users configured for EAP-PEAP not being able to connect to the network, when a Cisco Wireless LAN Controller (WLC) is deployed using local EAP, typically points to a misconfiguration in the local EAP profile on the WLC. EAP-PEAP relies on a server-side certificate to create a secure TLS tunnel for the authentication process. If the local EAP profile is not correctly configured with the proper certificate or other necessary settings, the authentication process will fail, preventing users from connecting. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )
