Explanation in Detail
In general, Cisco switches? models are started with WS-. WS-C means the switch products and the products with WS-X begining refer to the engines or modules of switches. In addition, there is WS-G which means the Gigabit fiber optic transceiver modules of switches. Now, I explain the detailed meaning of each letter in the model through a few of examples.
eg. WS-C3560G-24TS-S

  • W ? stands for IPSEC 40bit encryption;
  • S ? means switchboard;
  • C ? means the fixed-configuration switch;
  • 3650 ? refers to the seires;
  • G ? means all the interfaces are supported Gigabit or more. If there is no letter ?G? here, it shows that the mainly port of this switch is 10/100M or 100M;
  • 24 ? here means there are 24 ports of this switch;
  • T ? stands for port of BaseT port; sometimes, there is letter ?P? here which means BaseT port which supports PoE at the same time;
  • S ? the S behind T means the extended interface is SFP type interface and uplink;

Note: There are also ?D? or ?C? or ?W?repalcing ?T? or ?S? here, which respectively means 10Gigabit Ethernet XENPAK port and uplink, T/SPF and uplink, Integrated wireless LAN controller(50 support for up to 50 access points). Some combination meaning as following:
TT ? common port and uplink port are both BaseT;
LC ? common port is BaseT and partially support PoE(4 ports) uplink port are BaseT/SFP;
PC ? common port is BaseT and all support PoE(24 ports) uplink port are BaseT/SFP;
TC ?common port is BaseT and uplink port are all BaseT/SFP;
TS ? common port is BaseT and uplink port are all SFP;
PS ? common port is BaseT and all support the PoE, uplink port are all SFP;
FS ? common port is 100BaseFX and uplink port are all SFP;
when there is only T, it means there is no uplink port in the switch.

Primary Features and Benefits

Ease of Use: ?Plug-and-Play? Configuration

A working stack is self-managing and self-configuring. When switches are added or removed, the master switch automatically loads the Cisco IOS®Software revision running on the stack to the new switch, loads the global configuration parameters, and updates all the routing tables to reflect changes. Upgrades are applied universally and simultaneously to all members of the stack.

The Cisco Catalyst 3750 Series stacks up to nine switches as a single logical unit for a total of 468 Ethernet or PoE 10/100 ports, or 468 Ethernet 10/100/1000 ports or PoE 10/100/1000 ports, or nine 10 Gigabit Ethernet ports. Additional port combinations can be created by connecting the Cisco Catalyst 3750-E Series Switches to the stack. Individual 10/100, 10/100/1000, and 10 Gigabit Ethernet units can be joined in any combination to evolve with network needs.

Return on Investment Through Lower Operations Costs

The automatic Cisco IOS Software version checking and loading of the global configuration parameters provide the first level of operational time saving. The second level is added during the event of an outage. When you remove a troubled switch from an existing stack of switches and replace it with another switch, the master switch will recognize this as a maintenance outage and automatically reload the port-level configuration that was on the previous switch without user intervention. This allows IT managers to have local personnel in remote locations perform maintenance tasks instead of sending costly technicians out for a few minutes of work, thus saving thousands of dollars in operational costs.

Mix-and-Match Switch Types: Pay as You Expand Your Network

Stacks can be created with any combination of Cisco Catalyst 3750 and Cisco Catalyst 3750-E switches. Customers who need a mixture of 10/100 and 10/100/1000 ports, PoE, and wiring-closet aggregation capability can incrementally develop the access environment, paying only for what they need. When uplink capacity needs to be increased, you can easily upgrade your bandwidth by adding a 10 Gigabit Ethernet version to the stack and upgrade your Gigabit Ethernet links with 10 Gigabit Ethernet on the existing fiber.

Integrated Wireless LAN Controller

The Cisco Catalyst 3750G Integrated Wireless LAN Controller integrates wireless LAN controller functions into the Cisco Catalyst 3750G Series Switches and delivers improved operating efficiency and WLAN security, mobility, and ease of use for business-critical wireless LANs. The Cisco Catalyst 3750G Integrated Wireless LAN Controller delivers centralized security policies, wireless intrusion prevention system (IPS) capabilities, award-winning RF management, QoS, and Layer 3 fast secure roaming for WLANs. As a core component of the Cisco Unified Wireless Network, the Cisco Catalyst 3750G Integrated Wireless LAN Controller provides the control, security, redundancy, and reliability that network managers need to scale and manage their wireless networks as easily as they scale and manage their traditional wired networks.

Availability: Uninterrupted Performance at Layer 2 and Layer 3

The Cisco Catalyst 3750 Series increases availability for stackable switches. Each switch can operate as both a master controller and a forwarding processor. Each switch in the stack can serve as a master, creating a 1:N availability scheme for network control. In the unlikely event of a single unit failure, all other units continue to forward traffic and maintain operation.

Smart Multicast: A New Level of Efficiency for Converged Networks

With Cisco StackWise technology, the Cisco Catalyst 3750 Series offers greater efficiency for multicast applications such as video. Each data packet is put onto the backplane only once, which provides more effective support for more data streams.

Superior Quality of Service Across the Stack and at Wire Speed

The Cisco Catalyst 3750-E and 3750 Series offer Gigabit and 10 Gigabit Ethernet speed with intelligent services that keep everything flowing smoothly, even at 10 times the normal network speed. Mechanisms for marking, classification, and scheduling deliver best-in-class performance for data, voice, and video traffic, all at wire speed.

Network Security: Granular Control for the Access Environment

The Cisco Catalyst 3750 Series supports a comprehensive set of security features for connectivity and access control, including ACLs, authentication, port-level security, and identity-based network services with 802.1x and extensions. This set of comprehensive features not only helps prevent external attacks, but also defends the network against ?man-in-the-middle? attacks, a primary concern in today?s business environment.

Single IP Management: Many Switches, One Address

Each Cisco Catalyst 3750 Series stack is managed as a single object and has a single IP address. Single IP management is supported for activities such as fault detection, VLAN creation and modification, network security, and QoS controls.

Jumbo Frames: Support for High-Demand Applications

The Cisco Catalyst 3750 Series supports jumbo frames on the 10/100/1000 configurations for advanced data and video applications requiring very large frames. All Cisco Catalyst 3750-E Series switch models also support jumbo frames.

IPv6 Support

The Cisco Catalyst 3750 Series supports IPv6 routing in hardware for maximum performance. As network devices grow and the need for larger addressing and higher security becomes critical, the Cisco Catalyst 3750 Series will be ready to meet the requirement.

Standard PoE Support: Graceful Addition of IP Communications

The Cisco Catalyst 3750 and 3750G PoE models support Cisco IP phones and Cisco Aironet® wireless LAN (WLAN) access points, as well as any IEEE 802.3af-compliant end device. The Cisco Catalyst 3750 and 3750G 24-port versions can support 24 simultaneous full-powered PoE ports at 15.4W for maximum powered device support. The 48-port versions can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between.

10 Gigabit Ethernet Support: Increased Uplink Bandwidth for Gigabit Ethernet Deployments

The Cisco Catalyst 3750 Series allows network managers to incrementally add IEEE 802.3ae-compliant 10 Gigabit Ethernet connectivity in their wiring closets or grid clusters, further facilitating and enhancing Gigabit Ethernet networks. This provides investment protection to customers who want to use their existing fiber plant, add uplink bandwidth capacity to their switching stacks, and provide higher performance to applications and users. The Cisco Catalyst 3750-E Series offers an even greater variety of 10 Gigabit Ethernet port configuration switches.
