Chapter 1 Overview Management Options Advantages of Using CMS and Clustering Switches Using CMS and switch clusters can simplify and minimize your configuration and monitoring tasks. You can use Cisco switch clustering technology to manage up to 16 interconnected supported Catalyst switches through one IP address as if they were a single entity. This can conserve IP addresses if you have a limited number of them. CMS is the easiest interface to use and makes switch and switch cluster management accessible to authorized users from any PC on your network. By using switch clusters and CMS, you can • Manage and monitor interconnected Catalyst switches, regardless of their geographic proximity and interconnection media, including Ethernet, Fast Ethernet, Fast EtherChannel, Cisco GigaStack Gigabit Interface Converter (GBIC), Gigabit Ethernet, and Gigabit EtherChannel connections. Refer to the release notes (http://www.cisco.com/univercd/cc/td/doc/product/lan/c2900xl/index.htm) for a list of supported switches. • Accomplish multiple configuration tasks from a single CMS window without needing to remember CLI commands to accomplish specific tasks. • Apply actions from CMS to multiple ports and multiple switches at the same time to avoid re-entering the same commands for each individual port or switch. Here are some examples of globally setting and managing multiple ports and switches: - Port configuration such as speed and duplex settings - Port and console port security - NTP, STP, VLAN, and quality of service (QoS) configuration - Inventory and statistic reporting and link- and switch-level monitoring and troubleshooting - Group software upgrade • View a topology of interconnected devices to identify existing switch clusters and eligible switches that can join a cluster. You can also use the topology to quickly identify link information between switches. • Monitor real-time status of a switch or multiple switches from the LEDs on the front-panel images. The system, redundant power system (RPS), and port LED colors on the images are similar to those used on the physical LEDs themselves. • Use an interactive mode that takes you step-by-step through VLAN and voice VLAN (VVID) configuration. • Use a wizard that prompts you to provide only minimal required information to configure VVIDs.
