Preparing For Snmp Management; Setting An Ip Address Using Bootp - IBM 8237 Installation And User Manual

Preparing for SNMP Management

SNMP management requires that you have a managed stack: that is, that your stack
contain at least one 8237 Model 002 or Model 003. Model 002 incorporates an
SNMP agent and Model 003 incorporates an RMON agent that implements the
SNMP protocol.
Model 002 supports the following MIBs:
Model 003 supports all of the above, as well as the RMON MIB (RFC 1757).
These MIBs can be managed by most network management applications, including
IBM Nways Manager for Windows, Nways Campus Manager LAN for AIX, and
Nways Campus LAN for HP-UX. The 8237 supports SNMP/IPX and Novell HMI
specifications, enabling this system to be integrated seamlessly into the NetWare
environment.
Before you can use an SNMP-based network management application, you must
configure your primary 8237 management agent using either the user interface
program or BootP. For information on the user interface program, see "The 8237
User Interface Program" on page 3-1.

Setting an IP Address Using BootP

If you have selected one of the BootP options on the Hub Configuration panel
(Figure 3-12 on page 3-16), the 8237 automatically sends out BootP requests every
6 seconds for up to 2 minutes after a power-up. The BootP request contains the
MAC address of the 8237.
The requests seek a BootP server, which you must have previously configured with
an address resolution table containing MAC addresses and corresponding IP
addresses. When the BootP server receives the request, it sends an IP address to
the requesting 8237's MAC address.
NOTE: BootP requests will not pass through routers.
BootP servers vary from manufacturer to manufacturer, so use the following
example for reference only. Refer to your BootP server's documentation for specific
instructions.

In the example in Figure 3-35, the first line is the locally administered name of the
device that will receive the IP address, "HT" is its hardware type, "HA" is its MAC
