CISCO CATALYST SWITCHES

Cisco has recently released new cisco switches in india that are compatible with Cisco Catalyst Multigigabit Technology (mGiG), a revolutionary technology that achieves multigigabit speeds (2.5Gbps and 5Gbps) using Category 5e cables. This technology makes it possible to construct wired LAN networks with sufficient performance to support the super high-speed wireless LAN using IEEE 802.11ac, without replacing the existing cabling infrastructure. mGig is currently supported on one model in the Cisco Catalyst 3560-CX Series, two models in the Cisco Catalyst 3850 Series, and via a line card on the Cisco Catalyst 4500E Series. In addition to the mGig compatible models, a new lineup of models have been introduced including the Cisco Catalyst 2960-CX/3560-CX Series models and teh Cisco Catalyst 3850 Series models equipped with SFP + module slots.


Cisco Catalyst 2960-CX Series : L2 compact switches suitable for deployment in the access layer. These switches deliver basic network services even outside the wiring closet.

Cisco Catalyst 3560-CX Series :  L3 compact switches suitable for deployment in the access layer. These switches deliver advanced network services even outside the wiring closet.

Cisco Catalyst 2960-Plus Series : L2 fixed-configuration switches suitable for deployment in the access layer. FE is supported on all down link ports.

Cisco Catalyst 2960-X Series : L2/L3 fixed-configuration switches suitable for deployment in the access layer. GE and stacking are supported on all down link ports.

Cisco Catalyst 3650 Series : L2/L3 fixed-configuration switches suitable for deployment inthe access layer or core layer. provide a wireless controller function to server as an integrated platform for wired/wireless LAN networks.

Cisco Catalyst 3850 Series : Next-generation L2/L3 fixed configuration switches for deployment in the access layer or core layer. Provide a wireless controller function to server as an integrated platform for wired/wireless LAN networks.

Cisco Catalyst 4500E Series :  L2/L3 modular switches suitable for deployment int he access layer or core layer. The superior cost performance of these switches ensure the protection of investment over long periods.

Cisco Catalyst 4500-X Series : L3 fixed-configuration switches suitable for deployment in the core layer. Deliver excellent expandability and performance in environments with space constraints.

Cisco Catalyst 6500 Series : L3 modular switches suitable for deployment in the core layer. Provide a wide range of network services thanks to their top-of-the- industry performance.

Cisco Catalyst 6800 Series : L3 fixed-configuration/modular switches suitable for deployment in the core layer Provide network services optimized for 10/40/100 Gigabit Ethernet.

 

SELECTION OF CISCO CATALYST SWITCHES

Access Switches and Core Switches

Medium-sized corporate networks today are generally configured in two layers with access switches and core switches. Access switches are used to connect the end devices such as client PCs. IP phones and wireless access points; and core switches are used to consolidate lines by connecting multiple access switches. Switches with higher performance than access switches should be selected for core switches as their role is to consolidate a large number of lines.

L2 Switches and L3 Switches

Switches can be categorized into L2 Switches (Layer 2 switches) and L3 switches (Layer 3 switches) based on their functionality. In general, L2 switches are used for access switches and L3 switches are used for core switches, respectively. However, L3 switches should also be selected for access switches when offering services with
higher added value to the end users such as MACsec, which is a part of the Cisco TrustSec solution. The Cisco Catalyst 3650/3850/4500E Series support the upgrade from L2 to L3 switches via a Cisco IOS upgrade license.

CONFIGURATION / CONNECTION EXAMPLES

 

 

Fixed Configuration Switches and Modular Switches

Typically, fixed configuration switches (or box-typed switches) are referred to as having low cost and low performance; and modular switches (or chassis type switches) are referred to as having high cost and high performance. However, when the port unit prices of multiple fixed-configuration switches and a single modular switch are put to comparison, the latter cost may become lower as the number of ports increases.

High performance switches should generally be selected for the core switches. However, in a small sized network, a sufficient performance and redundant configuration can be achieved by connecting the fixed configuration Cisco Catalyst 3650/3850 Series switches in a stack.

Compact Switches

In some physical environments such as an office, it may be impossible or labor and cost intensive to run separate wiring from access switches installed in a wiring closet to the end devices such as a client PC, IP phone and wireless access points. The Cisco Catalyst 2960-CX/3560-CX Series compact switches have been developed to resolve these issues.
