Table 1 has the following columns:

Specify how the MAC address is assigned to the client. The following are possible: 
–  Automatic 
The client automatically adopts the source MAC address of the first frame that it 
receives over the Ethernet interface. 
–  Manual 
If you select "Manual", enter the MAC address in the "MAC Address" column. 
–  Own 
The client uses the MAC address of the Ethernet interface for the WLAN interface. 
–  Layer 2 Tunnel 
The client uses the MAC address of the Ethernet interface for the WLAN interface. 
The network is also informed of the MAC addresses connected to the Ethernet 
interface of the client. Up to eight MAC addresses can be used. 
● 
 
If you have selected "Manual" for "MAC Mode", enter the MAC address of the client. 
● 
 
–  Enabled 
In client mode, the SCALANCE W device attempts to connect to the access point that 
corresponds to the security settings of security context 1. The clients can only connect 
to the access point on which the "Broadcast SSID" option is enabled. 
–  Disabled 
The client attempts to connect to the access point from the SSID list whose security 
settings match one of the defined security contexts. 
● 
 
–  Enabled 
After changing to a different access point, a check is made to find out whether the 
IPv4 address of the client is still valid. If he IPv4 address is invalid, a new IPv4 
address is requested from the DHCP server. 
–  Disabled 
If the client changes to a different access point the IPv4 address is not checked.
