WLAN Basic Business Profile
Wireless Local Area Network WLAN (Wireless Local Area Network) broadly refers to radio waves, laser, infrared and the like instead of the network part or all of the wired LAN transmission medium constituted. WLAN technology described in this article is based on the 802.11 family of standards, i.e., the high-frequency signal (e.g., 2.4GHz or 5GHz) as a wireless LAN transmission medium.
802.11 is a wireless network communications industry standard IEEE 1997 is defined as WLAN. Since this standard and constantly replenished and improved, forming 802.11 standard series, for example 802.11,802.11a, 802.11b, 802.11e, 802.11g, 802.11i, 802.11n, 802.11ac and so on.

Business needs
Business users through WLAN access network to meet the most basic needs of mobile office. And occurs when the mobile roaming within the coverage area, without affecting the user's service usage.
Configuration process
Configuration Roadmap
It follows the idea of a small network configuration WLAN basic service:
- Disposed between the AP, AC and upper-layer network devices implement Layer communicate.
- AC is configured as a DHCP server assigns an IP address STA and AP.
- AP arranged on the line.
- Create an AP group, for the same configuration will need to be added to the AP AP are set to achieve a unified configuration.
- Configuration parameters of the AC system, comprising an interface for communication between the source country code, AC and AP.
- AP authentication mode on-line and off-line introducing AP, AP implemented on a normal line.
- WLAN service configuration parameters to achieve STA WLAN access network functions.
configuration list
AC configuration:
1, the configuration AC, so that can be transmitted between the AP and AC CAPWAP message
# Configuration AC, the upstream interface GE0 / 0/2 added VLANs 100 (management VLAN)
<6005> sysname AC # 创建vlan100、101 [AC] vlan batch 100 to 101
[AC]interface gigabitethernet 0/0/2
[ACgigabitethernet 0/0/2]port link-type access
[ACgigabitethernet 0/0/2]port default vlan 100
AC # Configure downlink interface GE0 / 0/1 was added VLAN101 (service VLAN)
[AC] interface gigabitethernet 0/0/1 [AC-GigabitEthernet0/0/1] port link-type trunk [AC-GigabitEthernet0/0/1] port trunk pvid vlan 101 [AC-GigabitEthernet0/0/1] port trunk allow-pass vlan all [AC]quit
2, AC arranged as a DHCP server, the IP address assigned to the STA and AP
# Configure the DHCP server based on the interface address pool, wherein, VLANIF 100 interface provides an IP address for the AP, VLANIF101 provide IP addresses for the STA.
[AC] dhcp enable [AC] interface vlanif 100 [AC-Vlanif100] ip address 169.254.158.62 24 [AC-Vlanif100] dhcp select interface [AC-Vlanif100] quit [AC] interface vlanif 101 [AC-Vlanif101] ip address 192.168.36.2 24 [AC-Vlanif101] dhcp select interface [AC-Vlanif101] quit
