Select WEP Key 1 as Transmit Key for EAP Authentication
If you use Network-EAP as the authentication type on your wireless network, you must select key 1 as
the transmit key on the access point AP Radio Data Encryption page. The access point uses the WEP key
you enter in key slot 1 to encrypt multicast and broadcast data signals that it sends to EAP-enabled client
devices. Because the access point transmits the WEP key used for multicast messages to the
EAP-enabled client device during the EAP authentication process, that key does not have to appear in
the EAP-enabled device’s WEP key list. The access point uses a dynamic WEP key to encrypt unicast
messages to EAP-enabled clients. When you set up a repeater access point to authenticate as a LEAP
client, the repeater derives a dynamic WEP key and uses it to communicate with the root access point.
Repeaters not set up for LEAP authentication use static WEP keys when communicating with other
access points.

If you do not use EAP authentication on your wireless network, you can select any WEP key as the
transmit key. If you use EAP authentication and you enable broadcast key rotation, you can enable
WEP without entering WEP keys.

MIB File Compatible with Firmware Version 11.00 and Later
The access point MIB file (AWCVX-MIB) is supported only by access point firmware version 11.00 and
later. Earlier versions of firmware do not support this MIB. You can download the access point MIB at
later. Earlier versions of firmware do not support this MIB. You can download the access point MIB at

This section lists important information about access points running firmware version 11.42T.
New Default Setting for Data Beacon Rate (DTIM)
In firmware version 11.42T, the default setting for Data Beacon Rate (DTIM) on the AP Radio Hardware
page is 1. This setting determines how often the access point’s beacon contains a delivery traffic
indication message (DTIM). The DTIM tells power-save client devices that a packet is waiting for them.
page is 1. This setting determines how often the access point’s beacon contains a delivery traffic
indication message (DTIM). The DTIM tells power-save client devices that a packet is waiting for them.
The new default setting causes client devices using power-save mode to wake up more often than the
default setting in firmware version 11.40T, which was 2. To conserve battery power in client devices
using power-save mode, increase the Data Beacon Rate (DTIM) setting.

Software Configuration Guide for more information on this setting.
Set Flow Control to None or Xon/Xoff When Using Terminal Emulator
The terminal emulator flow control setting for 1200 series access points (none or Xon/Xoff) differs from
the flow control setting for 340 and 350 series access points (none, Xon/Xoff, or Hardware).
