3Com WX4400 3CRWX440095A manual MAP Overview, Through radio signals, Layer 2 or Layer 3 networks

10	CONFIGURING MAP ACCESS
	POINTS

	MAPs contain radios that provide networking between your wired
	network and IEEE 802.11 wireless users. A MAP connects to the wired
	network through a 10/100 Ethernet link and connects to wireless users
	through radio signals.
MAP Overview	Figure 8 shows an example of a 3Com network containing MAPs and WX
	switches. A MAP can be directly connected to a WX switch port or
	indirectly connected to a WX switch through a Layer 2 or IPv4 Layer 3
	network. For redundancy, a MAP can have one of the following
	combinations of multiple connections:
	„ Two direct connections to a single WX or two WX switches
	„ Up to four indirect connections to WX switches through intermediate
	Layer 2 or Layer 3 networks
	„ One direct connection to a WX and up to three indirect connections
	to WX switches through intermediate Layer 2 or Layer 3 networks
