Configuring CMS
Access to Older Switches In a Cluster
If your cluster has these member switches running earlier software releases and if you have read-only
access to these member switches, some configuration windows for those switches display incomplete
information:
• Catalyst 2900 XL or Catalyst 3500 XL member switches running Cisco IOS Release 12.0(5)WC2
or earlier
• Catalyst 2950 member switches running Cisco IOS Release 12.0(5)WC2 or earlier
For more information about this limitation, refer to the release notes.
These switches do not support read-only mode on CMS:
• Catalyst 1900 and Catalyst 2820 switches
• Catalyst 2900 XL switches with 4-MB CPU DRAM
In read-only mode, these switches appear as unavailable devices and cannot be configured from CMS.
Configuring CMS
This section contains these topics that describe the requirements and configuration information for CMS:
• “CMS Requirements” section on page 3-7
• “Cross-Platform Considerations” section on page 3-9
• “Launching CMS” section on page 3-10
CMS Requirements
This section describes the hardware and software requirements for running CMS:
• “Minimum Hardware Configuration” section on page 3-7
• “Operating System and Browser Support” section on page 3-8
• “Browser Plug-In Requirements” section on page 3-8
• “Specifying an HTTP Port (Nondefault Configuration Only)” section on page 3-9
• “Configuring an Authentication Method (Nondefault Configuration Only)” section on page 3-9
Note The software requirements are automatically verified by the CMS Startup Report when you launch CMS.
For more information, see the “Launching CMS” section on page 3-10.
Minimum Hardware Configuration
The minimum PC requirement is a Pentium processor running at 233 MHz with 64 MB of DRAM. The
minimum UNIX workstation requirement is a Sun Ultra 1 running at 143 MHz with 64 MB of DRAM.
Table 3-2 lists the minimum platforms for running CMS.
