Configuring the DSL Router

HEthernet Interface

ÐAll DSL routers have an Ethernet interface with a unique MAC address assigned before shipping.

ÐThe Ethernet interface is a 10/100BaseT interface that automatically negotiates the rate. If all attached Ethernet devices support 100BaseT, the DSL router will default to 100BaseT. Otherwise, the DSL router operates at 10BaseT.

ÐThe DSL router can be configured for either DIX format or IEEE 802.3 format. When the DSL router is configured to use IEEE 802.3 format, the DSL router uses SNAP encapsulation as specified in RFC 1042.

ÐThe Hotwire 6302 IDSL and the 6342 SDSL Routers each have a hub configuration with four Ethernet connectors. The hub acts as a bit-level repeater. There is logically one Ethernet communications interface and one single collision domain.

ÐThe DSL router only accepts frames on the Ethernet interface with its own MAC address or a broadcast or multicast MAC address.

Ethernet and DSL Interface Identifiers

The following are the naming conventions used for the Hotwire DSL Router interfaces:

Heth1 (or e0) ± Ethernet interface name.

Hdsl1 (or d0) ± DSL interface name.

Service Domain IP Address Assignments

HMultiple Service Domains can be defined using network addresses and subnet masks.

HFor both the DSL interface and the Ethernet interface, four Service Domain IP Addresses and subnet masks can be defined.
