Configuring the Radio Network 4 - 7<br />

The downsi<strong>de</strong> of using RTS/CTS is that for each data packet you transmit,<br />

you must transmit and receive another packet, which will affect<br />

throughput.<br />

Packet Encapsulation (Encapsulation Menu)<br />

Configuration Radio I80211 Encapsulation Menu<br />

Option Value Description<br />

1 - Encap [ 802.1H ] - Default encapsulation method<br />

2 - Show - Show encapsulation table<br />

3 - Add - Add a protocol encapsulation method<br />

4 - Remove - Remove a protocol encapsulation method<br />

Enter an option number or name, “=” main menu, previous menu<br />

The Encap option and the related encapsulation table commands of<br />

Show, Add and Remove are of concern only when both of the following<br />

conditions exist:<br />

n You are assembling a wireless LAN that incorporates non-Aironet<br />

equipment.<br />

n The non-Aironet equipment uses a proprietary method of packet<br />

encapsulation that is different from the method used by Aironet.<br />

If your wireless LAN consists only of Aironet components, use the<br />

<strong>de</strong>fault Encap value of 802.1H and disregard the information in following<br />

discussion “Packet Encapsulation in Mixed Networks.”<br />

Packet Encapsulation in Mixed Networks<br />

Aironet LAN software allows you to assemble a wireless infrastructure<br />

using components from different suppliers. When combining equipment<br />

from different sources into a wireless LAN, you might need to accommodate<br />

different methods of packet addressing and conversion. The<br />

complete subject of packet addressing is beyond the scope of this manual,<br />

and our purpose here is to provi<strong>de</strong> only basic gui<strong>de</strong>lines and consi<strong>de</strong>rations.<br />

To combine a mix of equipment from alternate suppliers into a wireless<br />

LAN, you need to know the packet encapsulation methods used by the<br />

different suppliers. If you <strong>de</strong>termine that your infrastructure will be<br />

mixing packet encapsulation methods, you will first need to <strong>de</strong>termine
