Cisco WAN Switching Product Name Change

The Cisco WAN Switching products have new names. A switch in the BPX family is now part of the Cisco BPX® 8600 Series wide area switch family. The AXIS shelf is now called the Cisco MGX 8220 edge concentrator. Any switch in the IGX switch family (IGX 8, IGX 16 and IGX 32 wide-area switches) is now called the Cisco IGX 8400 series-wide area switch. The IGX 8 switch is now called the Cisco IGX 8410 wide-area switch. The IGX 16 switch is now called the Cisco IGX 8420 wide-area switch, and the IGX 32 switch is now called the Cisco IGX 8430 wide-area switch.
