Protocol Support
♦
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. It can assign IP addresses, an IP default gateway and
DNS servers to DHCP clients. 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.
♦
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 (IPPR)
Traditionally, routing is based on the destination address only and the router takes the shortest path
to forward a packet. IP Policy Routing (IPPR) provides a mechanism to override the default
routing behavior and alter the packet forwarding based on the policy defined by the network
administrator.
♦
PPP (Point-to-Point Protocol) link layer protocol.
♦
Transparent bridging (IEEE 802.1D) with bridge filters for unsupported network layer protocols.
