Chapter 15 Configuring the Catalyst 4500 Series Switch with Cisco Network Assistant
Managing a Network Using Cluster
Note If you have enabled clustering, you should disable clustering before configuring a community (see
Table 15-2).
Managing a Network Using Cluster
This section describes how to use clustering to create and manage Catalyst 4500 series switches using
the standalone Network Assistant application or the command-line interface (CLI).
Use clustering to group the switches in your network. You must enter the cluster run command on each
switch to be managed. The major advantage is that you can manage 16 devices with one IP address.
Note Clustering is the auto-discovering mechanism used in CNA 1.0.
Note For complete procedures for using Network Assistant to configure switch clusters, refer to
Getting Started with Cisco Network Assistant, available at:

Cluster Command Switch Requirements
A cluster command switch must meet these requirements:
• Uses Cisco IOS Release 12.2(20)EWA or later.
• Has an IP address.
• Cisco Discovery Protocol (CDP) version 2 is enabled (the default).
• Uses cluster-capable software and has clustering enabled.
• IP HTTP (or HTTPS) server is enabled.
Note On a Catalyst 4500 series switch, neither HTTP or HTTPS is enabled by default.
