How to Plan for Switch Clustering
Anticipating conflicts and compatibility issues is a high priority when you manage several switches
through a cluster. This section describes the guidelines, requirements, and caveats that you should
understand before you create the cluster:
• Automatic Discovery of Cluster Candidates and Members, page 6-5
• IP Addresses, page 6-11
• Hostnames, page 6-11
• Passwords, page 6-12
• SNMP Community Strings, page 6-12
• TACACS+ and RADIUS, page 6-12
• LRE Profiles, page 6-13
Refer to the release notes for the list of Catalyst switches eligible for switch clustering, including which
ones can be cluster command switches and which ones can only be cluster member switches, and for th e
required software versions and browser and Java plug-in configurations.
