Network Addressing

Communication Between the Hub and

Network Management Station

When an HP Management Module (HP J3210A) is installed in a stack of hubs,

they can be managed over the network by HP network management products,

for example HP AdvanceStack Assistant. These hubs can also be managed by

any other network management products that comply with the Simple Net-

work Management Protocol (SNMP) standard and have standard SNMP MIB-

browser functionality.

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 at least one of the segments

of the Management Module have a network layer address. This appendix

provides some background information on IPX and IP addressing.

For both IP and IPX networks, each segment receives a separate address. If

you are not putting ports on segments 2-4 and you did not add the Switch

Module to your stack, then you only need to assign an address to segment 1.

The Management Module is shipped with IP disabled on segments 2-4.
