Prerequisites
This chapter describes the factors that you should consider before installing CFM on a Windows NT or Solaris workstation. It includes the following sections:
Content Flow Monitor (CFM) is web-based status monitoring application within the CiscoWorks2000 product family for managing Cisco server load balancing devices. CFM consists of two components, a server and a client. You install and run the CFM software on a Windows NT or Solaris workstation and access it using a web browser from any workstation.
This section describes the system requirements and recommendations for the CFM server.
This guide is divided into chapters based on the platform on which you install the CFM software. Each installation chapter includes the server requirements and installation instructions specific to that platform.
CFM Release 1.0 supports running the CFM server on the following operating system platforms:
- Sun Solaris version 2.6 with the latest recommended patches from Sun Microsystems, Inc.
- Windows NT Workstation version 4.0 with Service Pack 5
or Windows NT Server version 4.0 with Service Pack 5
For information about the supported platforms, see the platform-specific installation chapters. For details on installing CFM on a Solaris workstation, see the "Installing CFM on Solaris" chapter. For details on installation the CFM on a Windows NT workstation, see the "Installing CFM on Windows NT" chapter.
The CFM client uses a web browser running on a workstation or PC to access the CFM server. You can use your web browser to access the CFM using any of the following hardware and software configurations:
- IBM PC-compatible computer with 300 Mhz processor---Windows NT version 4.0 with Service Pack 5, Windows 95, or Windows 98
- Sun SPARCstation or Sun Ultra 10---Solaris version 2.6
- IBM RISC System/6000 workstation---AIX version 4.3.3
- HP-UX workstation---HP-UX 10.2 or 11.0
- Hard disk space---10 MB minimum
- Web browser---To access the CFM server, you must have one of the following web browser applications on the client workstation:
- Netscape Navigator 4.6.1, 4.7, or later (Solaris or Windows)
The Accept all cookies option must be enabled. You can enable this option by selecting Edit > Preferences > Advanced and selecting the Accept all cookies checkbox
- Microsoft Internet Explorer version 5.0.1, or later (Windows only)
Java Virtual Machine version 5.00.317 or later is supported.
 |
Note Java, JavaScript, and Active-X features must be enabled in your web browser. For Netscape Navigator. |
CFM enables you to manage Cisco server load balancing (SLB) devices. This document assumes that you have already configured a device as a services manager and configured a device as a forwarding agent to handle load balancing traffic on your network server farm of real servers.
For information on configuring a services manager or a forwarding agent, refer to the Cisco MultiNode Load Balancing Feature Set for LocalDirector User Guide.
CFM uses the SNMP protocol to communicate with Cisco server load balancing devices. Follow the instructions provided in the following sections to enable SNMP on the LocalDirectors, services managers and forwarding agents that you want to monitor with CFM:
Because CFM uses SNMP to manage Cisco server load balancing devices, you must make sure that SNMP is properly configured on any services manager that you want to manage.
To configure SNMP on a services manager:
Step 1 Initiate a Telnet session to the LocalDirector that is configured as the services manager.
Step 2 At the command prompt, enter the following command to change to enable mode:
en enable_password
Where enable_password is the password required for entering enable mode for this LocalDirector.
Step 3 Enter the following command to change to configuration mode:
config t
Step 4 Configure the LocalDirector to accept SNMP command from the CFM server by entering the following command:
snmp-server host ip_address
Where ip_address is the IP address of the workstation where the CFM server is running.
|
Note You must configure the IP address of the CFM server so that the services manager can respond to SNMP requests from CFM. |
For more information on configuring the LocalDirector SNMP agent, refer to the "Command Reference" section of the Cisco LocalDirector Installation and Configuration Guide.
Because CFM uses SNMP to manage Cisco server load balancing devices, you must make sure that SNMP is properly configured on any forwarding agent that you want to manage.
To configure SNMP on a forwarding agent:
Step 1 Initiate a Telnet session to the router or switch routing module that is configured as the forwarding agent.
Step 2 At the command prompt, enter the following command to change to configuration mode:
config t
Step 3 Enter the following command to enable the forwarding agent to respond to SNMP requests:
snmp-server community public RO
Example
The following example is an excerpt from the configuration file for a forwarding agent that has been enabled to respond to SNMP requests:
!
snmp-server engineID local 00000009020000D063F74800
snmp-server community public RO
snmp-server community ciscoworks RW
snmp-server packetsize 8192
snmp-server contact hal
!
For more information on configuring the router SNMP agent, refer to the command reference for your router.
