MAC Addresses
Each MP-620 is assigned a unique block of 64 MAC addresses. 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 MP’s MAC address block is listed on a label on the back of the MP. If the MP
is already deployed and running on the network, you can display the MAC
address assignments by using the show {ap | dap} status command.
All MAC addresses on an MP are assigned based on the MP’s base MAC address,
as described in Table 3.
