Cisco IR500 Series WPAN Gateway and Range Extender Installation and Configuration Guide
Chapter 5 Operation and Configuration
WPAN Gateway and WPAN Range Extender Data Flow
• RS232 Port—the gateway RS232 serial port is used to connect RS232-based DA devices and
transport serial data traffic over TCP. The gateway configuration and management of the serial port
is done via CSMP and the CG-NMS.
• Raw TCP Serial Transport—the CGR800-WPAN makes the bi-directional serial data stream for the
serial ports available over IPv6 via the IEEE 802.15.4g interface.
WPAN Range Extender and Ethernet-based DA Devices
The WPAN gateway connects IPv4-based DA devices to the IPv6-based FAN by the following means:
• Ethernet Port—the gateway Ethernet port is used to provide IPv4 connectivity to DA devices. The
gateway exports configuration and management of the Ethernet port via CSMP and the CG-NMS.
• DHCP—the CGR800-WPAN implements a DHCP Server to support dynamic configuration of
IPv4-based DA devices. The CGR800-WPAN exports DHCP configuration and management via
CSMP.
• Mapping of Address and Port using Translation (MAP-T)—The gateway provides shared or
uniquely addressed IPv4 host connectivity to and across an IPv6 domain using MAP-T. The gateway
implements the MAP Customer Edge (CE) functionality, as described in draft-ietf-software-map-t.
Each MAP domain must also include a device that implements the MAP Border Router (BR)
functionality (e.g. ASR-1000). The gateway configuration and management of MAP-T is done via
CSMP and the CG-NMS.
• NAT44—The gateway uses NAT44 to translate private IPv4 addresses used by DA devices
connected to the Ethernet port to public IPv4 addresses used with MAP-T.
Role of the WPAN Range Extender
The WPAN range extender is an IEEE 802.15.4g-2012 IPv6 router device that allows additional
flexibility in locating IEEE 802.15.4g devices, resulting in extra connectivity among CG-Mesh devices.
For example, while CG-Mesh electric meters must be placed where electric metering occurs, the range
extender may be placed anywhere AC power is available. The range extenders support the full CG-Mesh
network platform, including IEEE 802.15.4g, IEEE 802.1X, IPv6, and RPL.
