Chapter 5 Wireless LAN

NXC-8160 User’s Guide

"

If you do not enable any wireless security on your NXC-8160, your network is 
accessible to any wireless networking device within range.

Allow Inter-Ess 

Forward

An Extended Service Set (ESS) consists of a series of overlapping BSSs, each 

containing an access point, with each access point connected together by a wired 

network. This type of wireless LAN topology is called an Infrastructure WLAN.
Select Enable to allow wireless clients using different SSIDs to communicate with 

each other. Traffic between them will not go through the NXC-8160.

Note: To allow Inter-ESS forwarding, you need to enable this 

feature on both SSIDs. The SSIDs should also belong to the 
same VLAN group if you activate VLAN.

Select Disable to stop communications between wireless clients using different 

SSIDs and all traffic will go through the NXC-8160.

VLAN (0-4095)

A VLAN (Virtual Local Area Network) allows a physical network to be partitioned 

into multiple logical networks. Devices on a logical network belong to one group.
Specify a VLAN ID number (between 0 and 4095) to have the SSID belong to one 

VLAN group. Otherwise, leave this field at its default (none). 

Disassociation 

Timeout

Enter the number of seconds (from 0 to 3600) for the NXC-8160 to wait before it 

automatically disconnect a wireless client from the wired network when there is no 

traffic sent to or from the wireless client. 

DTIM period

A DTIM (Delivery Traffic Indication Message) is used to tell the wireless clients in 

power-saving mode that a packet is to be sent to them.
Select a DTIM period (from 1 to 5) (in beacon intervals). This indicates how many 

broadcast and multicast packets can be transmitted to wireless clients between 

two DTIMs. 

Save

Click Save to save your changes back to the NXC-8160. Your changes take effect 

only after you click Apply in the Maintenance screen.
