Catalyst 2950 Desktop Switch Software Configuration Guide
78-14982-01
Chapter 1 Overview
Network Configuration Examples
By using switch clusters and CMS, you can:
• Manage and monitor interconnected Catalyst switches (refer to the release notes for a list of
supported 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.
• 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 settings
–
NTP, STP, VLAN, and quality of service (QoS) configurations
–
Inventory and statistic reporting and link and switch-level monitoring and troubleshooting
–
Group software upgrades
• 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
on the physical LEDs.
• Use an interactive mode that takes you step-by-step through configuring complex features such as
VLANs, ACLs, and QoS.
• Use a wizard that prompts you to provide the minimum required information to configure complex
features such as QoS priorities for video traffic, priority levels for data applications, and security.
For more information about CMS, see Chapter 3, “Getting Started with CMS.” For more information
about switch clusters, see Chapter 6, “Clustering Switches.”
Network Configuration Examples
This section provides network configuration concepts and includes examples of using the switch to
create dedicated network segments and interconnecting the segments through Fast Ethernet and Gigabit
Ethernet connections.
Design Concepts for Using the Switch
As your network users compete for network bandwidth, it takes longer to send and receive data. When
you configure your network, consider the bandwidth required by your network users and the relative
priority of the network applications they use.
Table 1-2 describes what can cause network performance to degrade and how you can configure your
network to increase the bandwidth available to your network users.
