A Public-Signed SAN (Subject Alternative Name) certificate allows multiple domain names to be protected with a single certificate. This is useful in a distributed environment like a guest portal on Cisco ISE, where there may be multiple nodes with different Common Names (CNs). Using a SAN certificate can prevent CN mismatch errors during SSL/TLS handshakes. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 If all APs are receiving multicast traffic instead of only those that need it, it indicates that Multicast Internet Group Management Protocol (IGMP) snooping is not enabled. IGMP snooping is a feature that allows a network switch to listen to IGMP network traffic and ensure that multicast packets are only sent to the ports associated with interested receivers, thus preventing unnecessary traffic on the network. References := CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

In a FlexConnect deployment, enabling FlexConnect Local Switching allows branch office APs to map client traffic directly onto the local LAN, bypassing the need to tunnel all traffic back to the WLC at the main campus. This is essential for corporate devices at branch offices to access local resources efficiently and to be mapped to the correct VLANs according to their VLAN tag ID and WLAN. This setting is not relevant for APs in Local mode at the main campus, as they already switch traffic locally by default.

The wireless client cannot reach the RUN state because it is not receiving an IP address. This is a crucial step in the connection process, as a valid IP address is necessary for the client to communicate on the network. Without it, the client cannot achieve the RUN state, which indicates full authentication and association.
