Network Addressing (HP 28688B and

HP 28699A Only)

The HP 28688B EtherTwist Hub Plus and the HP 28699A Hub Plus/48 can be managed

over the network by HP network management products, and any other network

management products that comply with the Simple Network Management Protocol

(SNMP) standard. The communication between the SNMP network management station

and the hub takes place using the network layer protocols, IPX for Novell networks, or IP

for TCP/IP networks.

Which protocol you use depends on the protocol being used by the network management

station. Additionally, if the network management station is on the other side of a router

from your hub, the protocol you run on both the hub and the network management station

depends on which protocol the router can handle.

The network layer communications require that the hub have a network layer address.

This appendix provides some background information on IPX and IP addressing.

IPX Addressing for Novell NetWare

The Novell NetWare network operating system uses a proprietary protocol called

Internetwork Packet Exchange (IPX). The IPX protocol firmware is always available on

the HP EtherTwist Hub Plus and Hub Plus/48; it becomes active when the hub gets an

IPX address. The IPX address consists of a network number and a device identification.

The address is automatically assigned to the hub as follows (no IPX configuration of the

hub is necessary):

The network number is automatically assigned by a router or file server on the

network that is running the IPX protocol.

The device identification is merely the hub’s station address (also known as the

MAC address, Ethernet address, or physical address). This address is a unique

12-digit hexadecimal number assigned to the hub at the factory.
