Explanation:
Access point (AP) monitor mode, sniffer mode, and rogue detector mode do not provide client connectivity.
After adding an AP to a wireless LAN controller (WLC), you can configure the AP to operate in one of six modes depending on your needs and the capability of the AP. Three of the modes, monitor mode, sniffer mode, and rogue detector mode, are used primarily for monitoring and administrative purposes and, thus, do not provide client connectivity. For example, you can place an AP in monitor mode to configure the AP to scan wireless traffic. You can place an AP in sniffer mode to configure the AP to scan for wireless traffic and to send the traffic to a management station running a tool such as Wireshark. You can configure an AP to operate in rogue detector mode to configure the AP to scan traffic on the wired connection in search of unauthorized APs and unauthorized clients on the wired network.
Hybrid remote edge access point (HREAP) mode, which is also known as FlexConnect, allows for client connectivity. An AP operating in HREAP mode can be remotely managed from a central location via a WAN link, which is useful when deploying APs to remote offices. This enables administrators to deploy an AP in the remote office without also needing to deploy a WLC to the office. Furthermore, APs operating in HREAP mode can provide client connectivity even if the connection to the remote WLC is lost.
An AP is in local mode by default. In this mode, the AP can connect to a WLC and can provide client connectivity. In addition, an AP operating in local mode monitors all wireless channels.
An AP operating in bridge mode can provide client connectivity. You can configure an AP for bridge mode in order to use the AP to connect two networks together. In addition, you can use this mode to configure a mesh network.
