Configuring WLSM Failover Chapter 12 Configuring WDS, Fast Secure Roaming, Radio Management, and Wireless Intrusion Detection tunnels, which keeps data traffic going between client and SUP. But because of the WLSM failure, the control traffic going between the access point and the WLSM is disrupted (as shown in Figure 12-18), which prevents the access points from accepting new client connections until the WLSM software is back online. Resilient tunnel recovery is automatic and does not require any configuration. Figure 12-18 Resilient Tunnel Recovery Data traffic SUP Client Access point Control traffic WLSM 146929 Active/Standby WLSM Failover In addition to resilient tunnel recovery, WLSM supports another level of resiliency by allowing you to deploy two WLSMs per chassis: an active WLSM and a standby WLSM. If the active WLSM fails, the standby WLSM becomes active and takes over the control traffic for existing and new access point clients without interrupting data traffic. This feature in addition to resilient tunnel recovery provide near-hot standby in case of WLSM failure. 12-32 Cisco IOS Software Configuration Guide for Cisco Aironet Access Points OL-8191-01
CHAPTER 13 Configuring RADIUS and TACACS+ Servers This chapter describes how to enable and configure the Remote Authentication Dial-In User Service (RADIUS) and Terminal Access Controller Access Control System Plus (TACACS+), that provides detailed accounting information and flexible administrative control over authentication and authorization processes. RADIUS and TACACS+ are facilitated through AAA and can be enabled only through AAA commands. Note You can configure your access point as a local authenticator to provide a backup for your main server or to provide authentication service on a network without a RADIUS server. See Chapter 11, “Configuring Authentication Types,” for detailed instructions on configuring your access point as a local authenticator. Note For complete syntax and usage information for the commands used in this chapter, refer to the Cisco IOS Security Command Reference for Release 12.2. This chapter contains these sections: • Configuring and Enabling RADIUS, page 13-2 • Configuring and Enabling TACACS+, page 13-22 OL-8191-01 Cisco IOS Software Configuration Guide for Cisco Aironet Access Points 13-1
