failover

The video walks you through different methods that Cisco Access Point uses to discover Wireless LAN Controller and how an AP makes a decision on which controllers to join. Each method will be demonstrated with their order of priority explained. We will mention the purpose of Master Controller and stress on importance of controller priming. Wireshark analysis will be performed throughout the lab for us to examine controller discovery and AP registration processes.

The video looks further into mechanism that IPv6 uses to provide default router information to local hosts on Cisco router. This includes ability to influence end hosts to choose a preferred default gateway. We will specifically look at Default Router Preference flag in the RA packet on Wireshark, as well as performing router failover and observe exactly host the end hosts change their default gateway. 

The video demonstrates the process of setting up a distributed deployment on Cisco ACS 5.4. We will go through a secondary ACS registration, moving log collector role to a secondary ACS, failover testing, and promoting a secondary ACS to be a primary. Along the process, we will also verify MAR cache distribution that was configured in the previous labs, and note the caveat in the feature.
