Getting to Know Your G.SHDSL Router
SNMP is only available if TCP/IP is configured on your Prestige.
IP Multicast
Deliver IP packets to a specific group of hosts using IP multicast. IGMP (Internet Group Management
Protocol) is the protocol used to support multicast groups. The latest version is version 2 (see RFC 2236);
the Prestige supports both versions 1 and 2.

IP Alias
IP Alias allows you to partition a physical network into logical networks over the same Ethernet interface.
The Prestige supports three logical LAN interfaces via its single physical Ethernet interface with the
Prestige itself as the gateway for each LAN network.

IP Policy Routing
IP Policy Routing provides a mechanism to override the default routing behavior and alter packet
forwarding based on the policies defined by the network administrator.

10/100MB Auto-negotiation Ethernet/Fast Ethernet Interface
This auto-negotiation feature allows the Prestige to detect the speed of incoming transmissions and adjust
appropriately, providing a faster data transfer on the Ethernet network as required. It enables fast data
transfer of either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending on your
Ethernet network.

Protocols Supported
• TCP/IP (Transmission Control Protocol/Internet Protocol) network layer protocol.
• PPP (Point-to-Point Protocol) link layer protocol.
• TCP/IP (Transmission Control Protocol/Internet Protocol) network layer protocol.
• PPP (Point-to-Point Protocol) link layer protocol.
• SUA™ (Single User Account) and NAT (Network Address Translation).
PAP and CHAP Security
The Prestige supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake
Authentication Protocol). CHAP is more secure than PAP; however, PAP is available on more platforms.

DHCP Support
DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain the
TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has built-in DHCP server
capability, enabled by default, which means it can assign IP addresses, an IP default gateway and DNS
servers to other systems that support the DHCP client. The Prestige can now also act as a surrogate DHCP
server (DHCP Relay) where it relays IP address assignment from the actual real DHCP server to the clients.
