Chapter 5 Clustering Switches Creating a Switch Cluster Network Port A network port cannot link cluster members. For more information about the network port, see the "Enabling a Network Port" section on page 7-6. NAT Commands When you create a cluster, Network Address Translation (NAT) commands are added to the configuration file of the command switch. Do not remove these commands. LRE Profiles A configuration conflict occurs if a switch cluster has Long-Reach Ethernet (LRE) switches that use both private and public profiles. If one LRE switch in a cluster is assigned a public profile, all LRE switches in that cluster must have that same public profile. Before you add an LRE switch to a cluster, make sure that you assign it the same public profile used by other LRE switches in the cluster. A cluster can have a mix of LRE switches that use different private profiles. Availability of Switch-Specific Features in Switch Clusters The menu bar on the command switch displays all options available from the switch cluster. Therefore, features specific to a member switch are available from the command-switch menu bar. For example, Device > LRE Profile appears in the command-switch menu bar when at least one Catalyst 2900 LRE XL switch is in the cluster. Creating a Switch Cluster Using CMS to create a cluster is easier than using the CLI commands. This section provides this information: • Enabling a Command Switch, page 5-20 • Adding Member Switches, page 5-21 • Creating a Cluster Standby Group, page 5-23 • Verifying a Switch Cluster, page 5-25 This section assumes you have already cabled the switches, as described in the switch hardware installation guide, and followed the guidelines described in the "Planning a Switch Cluster" section on page 5-5. Note Refer to the release notes (http://www.cisco.com/univercd/cc/td/doc/product/lan/c2900xl/index.htm) for the list of Catalyst switches eligible for switch clustering, including which ones can be command switches and which ones can only be member switches, and for the required software versions and browser and Java plug-in configurations. 78-6511-08 Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide 5-19
