EDCA Parameters
(Enhanced Distributed Channel Access) govern wireless data
from your Gateway to the client;
Client EDCA Parameters
govern wireless data from the
client to your Gateway.
set wireless wmm option [ off | on ]
Enables or disables wireless multi-media settings option, which allows you to fine tune WiFi
Multimedia Quality of Service (QoS) by transmitting data depending on Diffserv priority set-
tings. These priorities are mapped into four Access Categories (AC), in increasing order of
priority: Background (BK), Best Effort (BE), Video (VI), and Voice (VO). It requires WiFi Multi-
media-capable clients, usually a separate feature enabled at the client.

Wireless Privacy Settings
set wireless network-id privacy option { off | WEP | WPA-PSK |
WPA-802.1x }
Specifies the type of privacy enabled on the wireless LAN. off = no privacy; WEP = WEP
encryption; WPA-PSK = Wireless Protected Access/Pre-Shared Key; WPA-802.1x = Wireless
Protected Access/802.1x authentication. See
“
Privacy
” on page
126
for a discussion of
these options.
WPA provides Wireless Protected Access, the most secure option for your wireless net-
work. This mechanism provides the best data protection and access control. PSK requires
a Pre-Shared Key; 802.1x requires a RADIUS server for authentication.
WEP is Wired Equivalent Privacy, a method of encrypting data between the wireless Gate-
way and its clients. It is strongly recommended to turn this
on
as it is the primary way to
protect your network and data from intruders. Note that 40bit is the same as 64bit and will
work with either type of wireless client. The default is
off
.
A single key is selected (see
default-key
) for encryption of outbound/transmitted packets.
The WEP-enabled client must have the identical key, of the same length, in the identical
slot (1..4) as the wireless Gateway, in order to successfully receive and decrypt the
packet. Similarly, the client also has a ‘default’ key that it uses to encrypt its transmis-
sions. In order for the wireless Gateway to receive the client’s data, it must likewise have
the identical key, of the same length, in the same slot. For simplicity, a wireless Gateway
and its clients need only enter, share, and use the first key.
set wireless network-id privacy pre-shared-key
string
The Pre Shared Key is a passphrase shared between the Router and the clients and is
used to generate dynamically changing keys, when
WPA-PSK
is selected or enabled. The
passphrase can be 8 – 63 characters. It is recommended to use at least 20 characters for
best security.
set wireless network-id privacy default-keyid { 1...4 }
Specifies which WEP encryption key (of 4) the wireless Gateway will use to transmit data.
The client
must
have an identical matching key, in the same numeric slot, in order to suc-
cessfully decode. Note that a client allows you to choose which of its keys it will use to
transmit. Therefore, you must have an identical key in the same numeric slot on the Gate-
way.

CONFIG Commands
For simplicity, it is easiest to have both the Gateway and the client transmit with the same
key. The default is
1
.
set wireless network-id privacy encryption-key1-length
{40/64bit, 128bit, 256bit}
set wireless network-id privacy encryption-key2-length
{40/64bit, 128bit, 256bit}
set wireless network-id privacy encryption-key3-length
{40/64bit, 128bit, 256bit}
set wireless network-id privacy encryption-key4-length
{40/64bit, 128bit, 256bit}
Selects the length of each encryption key.
40bit
encryption is equivalent to
64bit
encryp-
tion. The longer the key, the stronger the encryption and the more difficult it is to break the
encryption.
set wireless network-id privacy encryption-key1 {
hexadecimal digits
}
set wireless network-id privacy encryption-key2 {
hexadecimal digits
}
set wireless network-id privacy encryption-key3 {
hexadecimal digits
}
set wireless network-id privacy encryption-key4 {
hexadecimal digits
}
The encryption keys. Enter keys using hexadecimal digits. For 40/64bit encryption, you
need 10 digits; 26 digits for 128bit, and 58 digits for 256bit WEP. Valid hexadecimal char-
acters are 0 – 9, a – f.
Example 40bit key:
02468ACE02.
Example 128bit key:
0123456789ABCDEF0123456789.
Example 256bit key:
592CA140F0A238B0C61AE162F592CA140F0A238B0C61AE162F21A09C.
You must set at least one of these keys, indicated by the default-keyid.
Wireless MAC Address Authorization Settings
set wireless mac-auth option { on | off }
Enabling this feature limits the MAC addresses that are allowed to access the LAN as well
as the WAN to specified MAC (hardware) addresses.
