Access Point Configuration Setting up Filter Control 5-36 The following example shows how to set the native VLAN ID and enable VLAN support. Note that to enable or disable VLAN support, you must reboot the access point. HP420(config)#native-vlanid 5 HP420(config)#vlan enable Reboot system now? : The following example shows how to enable filtering for management access and wireless-to-wireless communications. HP420(config)#filter loca-bridge HP420(config)#filter ap-manage HP420(config)# The following example shows how to enable protocol filtering, preventing the access point from forwarding Novell IPX frames.

Modifying Radio Settings Access Point Configuration Modifying Radio Settings The access point can operate in three standard modes, IEEE 802.11b only, 802.11g only, or a mixed 802.11b/802.11g mode. Not e Both the IEEE 802.11g and 802.11b standards operate within the 2.4 GHz band. In a wireless LAN environment there can often be interference from other 2.4 GHz devices, such as cordless phones. If you experience poor wireless LAN performance, try to limit any possible sources of radio interference within the service area. The IEEE 802.11g standard is an extension of the IEEE 802.11b standard and enables client stations with 802.11b wireless network cards to associate to an 802.11g access point. However, the 802.11b standard uses Complementary Code Keying (CCK) modulation technology to achieve a communication rate of up to 11 Mbps, whereas 802.11g uses Orthogonal Frequency Division Multiplexing (OFDM) to reach rates of up to 54 Mbps. (Note that the 802.11g standard is backward-compatible with 802.11b and therefore includes the ability to use OFDM or CCK modulation.) To support both 802.11g and 802.11b clients, the access point has to first communicate with all clients using CCK and only switch to OFDM for data transfers between 802.11g-compatible clients. This mechanism has the effect of reducing the maximum throughput for 802.11g clients in the network. Working in its mixed “b/g” mode, the access point will experience reduced data throughput, even if there are no 802.11b clients active in the network. To achieve a higher throughput, you can set the access point to operate in 802.11gonly mode, which ignores all 802.11b clients in the service area. Not e Both the IEEE 802.11g and 802.11b standards operate within the 2.4 GHz band. If you are operating in “802.11g-only” mode, any 802.11b devices in the service area will contribute to the radio frequency noise and affect network performance. Web: Modifying the Radio Working Mode and Settings The Port/Radio Settings window on the Configuration tab provides the basic settings for the access point’s radio operation. The access point’s radio channel settings are limited by local regulations, which determine the number of channels that are available. 5-37
