Figure 1 Dual-Homed Device Configuration
When setting the minimum router configuration you must use the dual-homed device router-side (secondary) IP address and
DNS name when configuring theIP hostnamefor the CWI client. This mapping is required for the client to view the notifications
from the router received by the dual-home instance of CWI. See the “Router Prerequisites” section on page 7.
If you have a dual-homed device in your network, you can use the standard or SSL encryption configurations. See the “Setting
Up theRequired Management Services with a Secure Connection” sectionon page 8 and “Setting Upthe Required Management
Services Without a Secure Connection” section on page 8 for procedures.
Prerequisites
Prerequisites ensure that the CWI client and router are correctly set up to allow them to communicate. Meeting all prerequisites
before starting any of the procedures in this guide is recommended to ensure successful communication between the CWI client
and router.
The following prerequisites are provided:
• CWI Client System Prerequisites, page 5
• Router Prerequisites, page 7
• CWI Client Prerequisites, page 7
Note If you are using the CORBA connections and require notifications, the router must be explicitly configured for each
client that is to receive notifications. These notifications include real-time inventory updates (for example online
insertion and removal [OIR]), alarms, and change of configuration events. See the “Router Prerequisites” section on
page 7 for information on configuring the router to send notifications to a specified client.
CWI Client System Prerequisites
The CWI client hardware requirements ensure that the CWI client has the proper verified system requirements for the chosen
platform.
The following system requirements for a CWI client are provided in the hardware platform tables:
• Windows-based PC (see Table 2)
• UNIX (see Table 3)
• Linux (see Table 4)
• Macintosh (see Table 5)
Table 2 Windows-Based PC Minimum System Requirements
Requirement Type Minimum Requirements
System hardware IBM PC-compatible 500 MHz PentiumIII minimum, 1.20 GHz Pentium IV recommended.
System software Windows 2000 or Windows XP.
Memory (RAM) 256 MB minimum, 512 MB recommended.
