D-Link Unified Access System Software User Manual 12/10/09 Field MAC Address AP Mode Location Authentication Password Profile Channel Table 267: Valid AP Configuration Description This field shows the MAC address of the AP. To change this field, you must delete the entire Valid AP configuration and then enter the correct MAC address from the page that lists all Valid APs. You can configure the AP to be in one of three modes: • Standalone: The AP acts as an individual access point in the network. You do not manage the AP by using the switch. Instead, you log on to the AP itself and manage it by using the Administrator Web User Interface (UI), CLI, or SNMP. If you select the Standalone mode, the screen refreshes and different fields appear. See the following table for the Standalone mode field descriptions. • Managed: The AP is part of the D-Link Unified Switch, and you manage it by using the Unified Switch. If an AP is in Managed Mode, the Administrator Web UI and SNMP services on the AP are disabled. • Rogue: Select Rogue as the AP mode if you wish to be notified (through an SNMP trap, if enabled) when this AP is detected in the network. Additionally, the when this AP is detected through an RF scan, the status is listed as Rogue. If you select the Rogue mode, the screen refreshes, and fields that do not apply to this mode are hidden. To help you identify the AP, you can enter a location. This field accepts up to 32 alphanumeric characters. You can require that the AP authenticate itself with the switch upon discovery. If you require authentication, which is a setting on the Basic Setup > Global tab, select the Edit option and enter the password in this field. The valid password range is between 8 and 63 alphanumeric characters. The password in this field must match the password configured on the AP. If you configure multiple AP Profiles, you can select the profile to assign to this AP. For more information about configuring AP Profiles, see "Advanced Global Settings" on page 506. The Channel defines the portion of the radio spectrum that the radio uses for transmitting and receiving. The range of channels and the default channel are determined by the Mode of the radio interface and the country in which the APs operate. In the United States, IEEE 802.11b, 802.11g, and 2.4 GHz 802.11n modes (802.11 b/g/n) support the use of channels 1 through 11 inclusive, while IEEE 802.11a and 5-GHz 802.11n modes supports a larger set of non-consecutive channels (36,40,44, 48, 52, 56, 60, 64, 149, 153, 157, 161, 165). Interference can occur when multiple access points within range of each other are broadcasting on the same or overlapping channels. The impact of this interference on network performance can intensify during busy times when a large amount of data and media traffic is competing for bandwidth. If you select auto, the AP scans the RF area for occupied channels and selects a channel from the available non-interfering, or clear channels. The AP selects the best channel whenever its radio or radios restart. If you specify a channel, make sure that the channel does not interfere with the channel that neighbor APs use. Note: The channel you set for an AP in the valid AP database is fixed and takes precedence over initial channel selection done by the AP and any automatic channel planning done by the switch. Note: For radios that use 802.11a and/or 5-GHz 802.11n mode, some countries have a regulatory domain that requires radar detection. For these countries (based on the country code setting), the radio automatically uses the 802.11h protocol for selecting the channel if radar is detected on the statically assigned channel.
