284 Configuring APs

NN47250-500 (Version 03.01)

Public and private SSIDs

Each radio can support the following types of SSIDs:
• Encrypted SSID—Clients using this SSID must use encryption. Use the encrypted SSID for secured
access to your enterprise network.
• Clear SSID—Clients using this SSID do not use encryption. Use the clear SSID for public access to
nonsecure portions of your network.
All supported AP models can support up to 32 SSIDs per radio. Each SSID can be encrypted or clear, and
beaconing can be enabled or disabled on an individual SSID basis.
Each radio has 32 MAC addresses and can therefore support up to 32 SSIDs, with one MAC address assigned
to each SSID as its BSSID. An AP's MAC address block is listed on a label on the back of the access point. If
the AP is already deployed and running on the network, you can display the MAC address assignments by
using the show ap status command.
All MAC addresses on an AP are assigned based on the AP’s base MAC address, as described in Table 7.

Encryption

Encrypted SSIDs can use the following encryption methods:
• Wi-Fi Protected Access (WPA)
• Non-WPA dynamic Wired Equivalent Privacy (WEP)
• Non-WPA static WEP
Dynamic WEP is enabled by default.
(For more information, including configuration instructions, see “Configuring user encryption” on page 361.)

Table 7: MAC address allocations on APs

AP All models

• The AP has a base MAC address. All the other addresses are
assigned based on this address.

Ethernet Ports All models

• Ethernet port 1 equals the AP base MAC address.
• Ethernet port 2 (if the AP model has one) equals the AP base
MAC address + 1.

Radios and SSIDs

2330/2330A/2330B

and Series 2332

• The 802.11b/g radio equals the AP base MAC address.
• The BSSIDs for the SSIDs configured on the 802.11b/g radio
end in even numbers. The first BSSID is equal to the AP’s
base MAC address. The next BSSID is equal to the AP’s base
MAC address + 2, and so on.
• The 802.11a radio equals the AP base MAC address + 1.
• The BSSIDs for the SSIDs configured on the 802.11a radio
end in odd numbers. The first BSSID is equal to the AP’s base
MAC address + 1. The next BSSID is equal to the AP’s base
MAC address + 3, and so on.
