COMMAND

DESCRIPTION

guard-interval [short

Sets Guard Interval to Short (increases data throughput) or Long (prioritize data

long]

integrity).

[no] amsdu

Enables Aggregated Mac Service Data Unit (AMSDU) for faster data transfer rates.

[no] ampdu

Enables Aggregated Mac Protocol Data Unit (AMPDU) for faster data transfer rates.

[no] block-ack

Adds the block ACK (BA) mechanism to increase data output.

exit

Leaves the sub-command mode.

6.9.1.1 WLAN General Commands Example

This example sets wireless slot 1 to use the IEEE 802.11b and IEEE 802.11g bands, channel 5, super mode, 50 % output power, and enables it.

Router(config)# wlan slot1

Router(config-wlan-slot)# band bg

Router(config-wlan-slot)# channel 5

Router(config-wlan-slot)# super

Router(config-wlan-slot)# output-power 50%

Router(config-wlan-slot)# activate

Router(config-wlan-slot)# exit

Router(config)#

6.9.2 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 33 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

Assigns the specified IP address and subnet mask to the specified interface. The

subnet_mask

no command clears the IP address and the subnet mask.

[no] ip gateway ip [metric

Adds the specified gateway for the interface. Sets the priority (relative to every

<0..15>]

gateway on every interface) for the specified gateway. The lower the number, the

 

higher the priority. The no command removes the gateway.
