Configuration Guide Configuring FAT APs
Working Principle
 Planning WLAN Subnets
In a wireless network, users can divide the network into multiple WLAN subnets by creating WLANs and specify the functions
and attributes of the WLANs in the WLAN configuration mode, thus providing different network services for wireless users.
 Associating an SSID
When a WLAN is created, an SSID must be associated with the WLAN. An SSID is only the name of a network service
domain. One SSID may map to one or more WLANs.
 Broadcasting SSIDs
In a WLAN, the AP regularly broadcasts the SSID information to announce existence of the wireless network. An STA can
discover a WLAN by searching for its SSID using a WNIC. To prevent illegal users from discovering WLANs by means of
SSID broadcasting and establishing illegal connections, the SSID broadcasting can be disabled.
 Multicast Rate
A multicast rate is a rate used when an AP sends multicast packets to STAs in a WLAN. The higher the multicast rate, the
higher the network performance, the higher requirement for the signal-noise ratio, and the higher the multicast packet loss
ratio of wireless terminals. On the other hand, the lower the multicast rate, the lower the network performance, the lower
requirement for the signal-noise ratio, and the lower the multicast packet loss ratio of wireless terminals.
1.3.2 Mapping a WLAN to Wireless Devices
After a WLAN is created, the WLAN needs to use wireless devices for wireless transmission.
Working Principle
 Configuring a dot11radio Subinterface
A dot11radio subinterface is a virtual wireless device, whose functions are basically the same as those of a physical wireless
device.
 Configuring a VLAN Encapsulated by a dot11radio Subinterface
VLAN attributes are needed when wireless packets of wireless devices are transferred in a wired network.
 Mapping a WLAN ID to a dot11radio Subinterface
Specify the virtual wireless devices to be used by a WLAN for wireless transmission.
1.3.3 Deploying and Optimizing the Network
After a WLAN is mapped to a wireless device, the RF parameters of the wireless device need to be set for deploying and
optimizing the network.
