14.2.4 Security Configuration
As with most 802.11 access points, security configuration is limited to configuring WEP, MAC
address filtering, and limiting management access based on source IP address.
14.2.4.1 Configuring WEP
To enter WEP keys, click the Security button on the Wireless Interfaces tab of the main access point
configuration screen. The security configuration is essentially WEP configuration; clicking the
Security button brings up the WEP configuration dialog box shown in Figure 14-7. The AP-1000
supports both "64-bit WEP" (40 secret bits) and "128-bit WEP" (104 secret bits), depending on the
wireless interface card used. "Silver" Orinoco cards support only the shorter length, and "Gold" cards
support both. Keys can be entered either as alphanumeric strings or hexadecimal strings. Figure 14-7
shows a key being entered with a leading 0x to denote that the key is being entered as a hexadecimal
number.

Closed Wireless System is a Lucent proprietary extension to 802.11 that drops any frames from
stations with a wildcard network name. It is compatible only with Orinoco cards and will drop traffic
from cards manufactured by other vendors.
14.2.4.2 Filtering management connections
Management is done over SNMP and is controlled through the SNMP tab on the main access point
configuration screen. The SNMP configuration box is shown in Figure 14-8. Read Password and
