LABEL DESCRIPTION
WEP Encryption Select Disable to allow wireless stations to communicate with the access
points without any data encryption.
Select
64-bit WEP or 128-bit WEP to enable data encryption.
Authentication
Method
Select Auto, Open System or Shared Key from the drop-down list box.
This field is N/A if WEP is not activated.
If WEP encryption is activated, the default setting is Auto.
ASCII Select this option to enter ASCII characters as the WEP keys.
Hex Select this option to enter hexadecimal characters as the WEP keys.
The preceding “0x” is entered automatically.
Key 1 to
Key 4 The WEP keys are used to encrypt data. Both the ZyAIR and the wireless
stations must use the same WEP key for data transmission.
If you chose
64-bit WEP , then enter any 5 ASCII characters or 10 hexadecimal
characters ("0-9", "A-F").
If you chose
128-bit WEP , then enter 13 ASCII characters or 26 hexadecimal
characters ("0-9", "A-F").
You must configure all four keys, but only one key can be activated at any one
time. The default key is key 1.
Enable Breathing
LED
Select this check box to enable the Breathing LED, also known as the ZyAIR
LED.
The blue ZyAIR LED is on when the ZyAIR is on and blinks (or breaths) when
data is being transmitted to/from its wireless stations. Clear the check box to
turn this LED off even when the ZyAIR is on and data is being transmitted/
received.
Enable Spanning
Tree Control (STP)
(R)STP detects and breaks network loops and provides backup links between
switches, bridges or routers. It allows a bridge to interact with other (R)STP -
compliant bridges in your network to ensure that only one path exists between
any two stations on the network. Select the check box to activate STP on the
ZyAIR.
Preamble Select a preamble type from the drop-down list menu. Choices are Long , Short
and Dynamic . The default setting is Long .
See the section on preamble for more information.
802.11 Mode Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to
associate with the ZyAIR.
Select
802.11g Only to allow only IEEE 802.11g compliant WLAN devices to
associate with the ZyAIR.
Select
Mixed to allow either IEEE802.11b or IEEE802.11g compliant WLAN
devices to associate with the ZyAIR. The transmission rate of your ZyAIR might
be reduced.
Max. Frame Burst Enable Maximum Frame Burst to help eliminate collisions in mixed-mode
networks (networks with both IEEE 802.11g and IEEE 802.11b traffic) and
enhance the performance of both pure IEEE 802.11g and mixed IEEE 802.11b/
g networks. Maximum Frame Burst sets the maximum time, in microseconds,
that the ZyAIR transmits IEEE 802.11g wireless traffic only.
Type the maximum frame burst between 0 and 1800 (650, 1000 or 1800
recommended). Enter 0 to disable this feature.
VLAN ID Enter a number from 1 to 255 to define this VLAN group. At least one device in
your network must belong to this VLAN group in order to manage the ZyAIR.
