6.7.2 WLAN Interface Commands
Use these commands to configure global settings that apply to all of the wireless LAN
interfaces you create on the WLAN card.
Table 31 WLAN Interface Commands
COMMAND DESCRIPTION
[no] interface ap_interface Creates the specified interface if necessary and enters sub-
command mode. The
no command deletes the specified
interface.
ap_interface: The name of the WLAN Access Point
interface. Use wlan-x-y where x equals the number of the
card slot and y equals the number of the individual WLAN
interface. For example, wlan-1-1.
[no] block-intra Enables intra-BSS blocking (prevents) wireless clients in this
profile’s BSS from communicating with one another.
group-key <30..30000> Sets the WPA2 group key update timer. This is the interval in
seconds for how often the AP sends a new group key out to
all clients.
[no] hide Obscures the SSID in the outgoing beacon frame so a station
cannot obtain the SSID through scanning.
idle <30..30000> Sets the WPA2 idle timeout. The ZyWALL automatically
disconnects a wireless station that has been inactive for this
number of seconds. The wireless station needs to enter the
username and password again before access to the wired
network is allowed.
[no] ip address ip subnet_mask Assigns the specified IP address and subnet mask to the
specified interface. The
no command clears the IP address
and the subnet mask.
[no]ip gateway ip [metric <0..15>] Adds the specified gateway for the interface. Sets the priority
(relative to every gateway on every interface) for the specified
gateway. The lower the number, the higher the priority. The
no command removes the gateway.
[no] mtu <576..2304> Specifies the Maximum Transmission Unit, which is the
maximum number of bytes in each packet moving through
this interface. The ZyWALL divides larger packets into smaller
fragments. The
no command resets the MTU to 1500.
reauth <30..30000> Sets the WPA2 reauthentication timer. This is at what interval
wireless stations have to resend usernames and passwords
in order to stay connected. If a RADIUS server authenticates
wireless stations, the reauthentication timer on the RADIUS
server has priority.
security mode {none | wep | wpa |
wpa-wpa2 | wpa2}
Sets what type of security the wireless interface uses.
none: applies no security.
wep: WEP security (extremely weak).
wpa: WPA security.
wpa-wpa2: WPA/WPA2-Enterprise or WPA/WPA2-PSK
security.
wpa2: WPA2 security (strongest option).
security wep <64 | 128> default-key
<1..4>
Sets WEP encryption to use a 64 or 128 bit key and selects
the default key.
security wep mode <open | share> Sets the WEP encryption to use open or shared key
authentication.
