Chapter 4. Using the Link Required Option Chapter 4. Using the Link Required Option As shown in Figure 4-1, Link Required is one of the options for the WLAP Mode entry on the RF Configuration screen. This option allows an access point to create a wireless link in the event it loses its Ethernet connection. Link Required can also be used to allow WLAPs to roam to another root access point if the original root access point loses its Ethernet connection. Network examples using the Link Required option are covered in the following subsections.

Figure 4-1: Setting the WLAP Mode to Link Required 4.1 Link Required for Maintaining Ethernet Link As previously mentioned, the Link Required option allows an access point to operate as a WLAP if it loses its Ethernet connection. An example network is shown in Figure 4-2. In this example, when access point B loses its Ethernet connection, it resets then makes a wireless link to the Ethernet through access point A.
