Configuring the AP is a bit different because it’s an access point (again, think hub), not a
router. I’ll configure this device from the CLI, but you can use an HTTP interface as well. But
you can’t use SDM. The HTTP interface will be easier to use when you start adding security
and when you get into some more complex configurations.

Even though the SSID configuration is the same as it is for the R2 routed radio interface,
notice there’s no IP address under the Dot11radio 0 interface. Why? It’s not a routed port, so
the IP address is instead placed under the bridge virtual interface (BVI). I also set a default gateway
so this device can be managed from outside the LAN.
You need to know that, just as with a switch, you don’t need to add an IP address to the
AP for it to function. I could just as easily have added the DHCP pool to the Corp router for
the wireless LAN and not added an IP address or pool to the AP at all, and it still would have
worked just the same.
