Bandwidth—Radio 1 supports 20 MHz, 40 MHz, and 80 MHz bandwidths, whereas
Radio 2 supports only 20 MHz and 40 MHz bandwidths.
•
Transmit power—You can configure transmit power on a per radio basis. By default,
the access point assigns 100% power to each radio at startup.
To increase capacity of the network, place access points closer together and reduce
the value of the transmit power. This helps reduce overlap and interference among
access points. A lower transmit power setting can also keep your network more secure
because weaker wireless signals are less likely to propagate outside of the physical
location of your network.
Virtual Access Point Configuration Overview
A virtual access point (VAP) simulates a physical access point. VAPs allow the wireless
LAN to be segmented into multiple broadcast domains that are the wireless equivalent
of Ethernet VLANs. A single AP is segregated into multiple individual virtual APs simulating
multiple APs in a single system.
VAPs allow different security mechanisms for different clients on the same access point.
VAPs also provide better control over broadcast and multicast traffic, which can help
avoid a negative performance impact on a wireless network. Each VAP is identified by a
configured Service Set Identifier (SSID) and a unique BasicServiceSetIdentifier (BSSID).
The AP supports multiple VLANs, which can be distributed across VAPs and radios.
Each virtual access point can be independently enabled or disabled with the exception
of VAP 0 on each radio. VAP 0 is the physical radio interface and is always enabled. To
disable operation of VAP 0, the radio itself must be disabled. VAP 0 is assigned to the
BSSID of the physical radio interface. Reviewer: Please confirm if this is accurate.
A VAP is configured on a per-radio basis. You can configure up to 8 VAPs per radio.
Configure the following options for each VAP:
•
Description (maximum length is 64)
•
SSID value for the VAP. The maximum length is 32. The SSID value can include only
letters, numerals, and the special characters . - _ @ #.
•
VLAN ID for the VAP. The value can range from 1 to 4094. The default value is 1.
•
The maximum number of clients that can connect to the VAP. The value can range
from 1 to 127.
•
Security for the AP. The AP supports several types of authentication methods that are
used by clients to connect to the access point. Each of these methods and their
associated parameters is configurable on a per VAP basis. By default, no security is in
place on the access point, so any wireless client can associate with it and access your
LAN. You configure secure wireless client access for each VAP.
•
None—The data transferred between clients and the access point is not encrypted.
This method allows clients to associate with the access point without any
authentication.
