Configuring mesh services
Different from a traditional WLAN, a WLAN mesh network allows for wireless connections between APs,
making the WLAN more mobile and flexible. Moreover, multi-hop wireless links can be established
between APs. From the perspective of end users, a WLAN mesh network has no difference from a
traditional WLAN.
Mesh overview
Basic concepts in WLAN mesh
Figure 321 Typical WLAN mesh network
As shown in Figure 321 , the concepts involved in WLAN mesh are described below.
Concept Description
Access controller (AC) A device that controls and manages all the APs in the WLAN.
Mesh point (MP)
A wireless AP that connects to a mesh portal point (MPP) through a
wireless connection but cannot have any client attached.
Mesh access point (MAP) An AP providing the mesh service and the access service concurrently.
Mesh portal point (MPP) A wireless AP that connects to an AC through a wired connection.
Mesh link A wireless link between MPs.
