Cluster Management and Membership

As with previous Catalyst 1900 releases, you can conﬁgure and monitor the switch as an

individual device in your network. To do this, you must assign it an IP address and

password and then use the options available from the Catalyst 1900 Switch Manager,

management console, SNMP, or the CLI. (See Chapter 3, “Conﬁguring and Monitoring

from the Switch Manager,” and Chapter 4, “Conﬁguring and Monitoring from the

Management Console.”)

The switch can also be a member of a switch cluster. A cluster is a group of connected

switches that are managed as a single entity. A cluster has a command switch and member

switches. The Catalyst 1900 switches can only be member switches. Certain models of the

Catalyst 2900 XL switches can be command switches, and all models of the Catalyst 3500

XL switches can be command switches.

The command switch is the central management point used to conﬁgure and monitor the

switch cluster. All communication with member switches is through the command switch

IP address. Clustering can simplify your network management tasks. For example, from a

command switch, you can manage and monitor member switches regardless of their

geographic location, and you can perform cluster-wide ﬁrmware upgrades.

Not all Catalyst 1900 conﬁguration and monitoring options are available from the Cluster

Management applications of the command switch; however, you can access the

Catalyst 1900 management interfaces (switch manager, management console, and CLI)

from the command switch at any time.

Each switch in a cluster can belong to only one cluster at a time. The switches in a cluster

can be in the same location, or they can be distributed across a network. The Catalyst 1900

switches can be connected to a cluster in a star or daisy-chain topology through copper or

ﬁber-optic cables.

To conﬁgure and monitor a Catalyst 1900 switch as a cluster member, the following

requirements must be met:

• The Catalyst 2900 XL or 3500 XL command switch must be running IOS Software

Release 12.0(5)XP or higher and must have an IP address assigned.

• The Catalyst 1900 switch must be

— Running ﬁrmware version 9.x or higher.

— CDP version 2-enabled.

— Connected to a cluster-member or to a command-switch port assigned to the
