To fight for freedom. It is rather for us to be here dedicated to the great task remaining before us that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion that we here highly resolve that these dead shall not have died in vain that this nation, under God, shall have a new birth of freedom and that government Of the people, by the people, for the people, shall not perish from the earth. Secondly, by an impressive expression of the public will and without regard to partisanship, we are committed to full support of all those resolute people everywhere who are resisting aggression and are thereby keeping war away from our hemisphere. By this support we express our determination that the democratic cause shall prevail, and we strengthen the defense and the security of our own nation.
Moreover, Layer 2 switches deliver the ability to increase bandwidth to the wiring closet without adding unnecessary complexity to the network.
At Layer 2, no modification is required to the frame content when going between Layer 1 interfaces, such as Fast Ethernet to 10 Gigabit Ethernet. In review, the network design properties of current-generation Layer 2 switches include the following: Layer 3 switches overcome the inadequacies of Layer 2 scalability by providing routing domains.
A Layer 3 switch performs everything on a packet that a traditional router does, including Assign analyzing documents following: Determines the forwarding path based on Layer 3 information Validates the integrity of the Layer 3 packet header via the Layer 3 checksum Verifies and decrements packet Time-To-Live TTL expiration Rewrites the source and destination MAC address during IP rewrites Updates Layer 2 CRC during Layer 3 rewrite Processes and responds to any option information in the packet such as the Internet Control Message Protocol ICMP record Updates forwarding statistics for network management applications Applies security controls and classification of service if required Layer 3 routing requires the ability of packet rewriting.
Packet rewriting occurs on any routed boundary. Figure illustrates the basic packet rewriting requirements of Layer 3 routing in an example in which two workstations are communicating using ICMP. Workstation A sends an ARP request for its default gateway.
Without knowing the MAC address of the default gateway, Workstation A cannot send any traffic outside the local subnet. Note that, in this example, Workstation A's default gateway is the Cisco router with two Ethernet interfaces.
Figure illustrates the Layer 2 and Layer 3 rewriting at different places along the path between Workstation A and B. This figure and example illustrate the fundamental operation of Layer 3 routing and switching.
The Assign analyzing documents difference between the packet-forwarding operation of a router and Layer 3 switching is the physical implementation.
Layer 3 switches use different hardware components and have greater port density than traditional routers.
These concepts of Layer 2 switching, Layer 3 forwarding, and Layer 3 switching are applied in a single platform: Because it is designed to handle high-performance LAN traffic, a Layer 3 switch is locatable when there is a need for a router and a switch within the network, cost effectively replacing the traditional router and router-on-a-stick designs of the past.
Understanding Multilayer Switching Multilayer switching combines Layer 2 switching and Layer 3 routing functionality. Generally, the networking field uses the terms Layer 3 switch and multilayer switch interchangeably to describe a switch that is capable of Layer 2 and Layer 3 switching.
In specific terms, multilayer switches move campus traffic at wire speed while satisfying Layer 3 connectivity requirements. This combination not only solves throughput problems but also helps to remove the conditions under which Layer 3 bottlenecks form.
Moreover, multilayer switches support many other Layer 2 and Layer 3 features besides routing and switching. For example, many multilayer switches support QoS marking. Combining both Layer 2 and Layer 3 functionality and features allows for ease of deployment and simplified network topologies.
Moreover, Layer 3 switches limit the scale of spanning tree by segmenting Layer 2, which eases network complexity. In addition, Layer 3 routing protocols enable load-balancing, fast convergence, scalability, and control compared to traditional Layer 2 features.
In review, multilayer switching is a marketing term used to refer to any Cisco switch capable of Layer 2 switching and Layer 3 routing. From a design perspective, all enterprise campus designs include multilayer switches in some aspect, most likely in the core or distribution layers.
Moreover, some campus designs are evolving to include an option for designing Layer 3 switching all the way to the access layer with a future option of supporting Layer 3 network ports on each individual access port.
Over the next few years, the trend in the campus is to move to a pure Layer 3 environment consisting of inexpensive Layer 3 switches.

The Most Effective Way of Organizing Your Files, Folders and Documents. By Brooks Duncan | 56 comments. One of the simplest and most overlooked aspects of being organized is .
For brevity, this section highlights a few popular models used in the campus, core backbone, and data center. For a complete list of Cisco switches, consult product documentation at Cisco.
They are found in a wide variety of installs not only including campus, data center, and backbone, but also found in deployment of services, WAN, branch, and so on in both enterprise and service provider networks.
Scalable modular switch up to 13 slots Supports up to 16 Gigabit Ethernet interfaces per slot in an over-subscription model Up to 80 Gbps of bandwidth per slot in current generation hardware Supports Cisco IOS with a plethora of Layer 2 and Layer 3 switching features Optionally supports up to Layer 7 features with specialized modules Integrated redundant and high-available power supplies, fans, and supervisor engineers Supports Layer 3 Non-Stop Forwarding NSF whereby routing peers are maintained during a supervisor switchover.
Backward capability and investment protection have lead to a long life cycle Cisco Catalyst Family of Switches The Cisco Catalyst family of switches is a vastly popular modular switch found in many campus networks at the distribution layer or in collapsed core networks of small to medium-sized networks.
Collapsed core designs combine the core and distribution layers into a single area. The Catalyst is one step down from the Catalyst but does support a wide array of Layer 2 and Layer 3 features.
In summary, the Cisco Catalyst family of switches are summarized as follows: Scalable module switch with up to 10 slots Supports multiple 10 Gigabit Ethernet interfaces per slot Supports Cisco IOS Supports both Layer 2 switching and Layer 3 switching Optionally supports integrated redundant and high-available power supplies and supervisor engines Cisco Catalyst G,and Family of Switches The Cisco Catalyst G,and family of switches are popular switches used in campus networks for fixed-port scenarios, most often the access layer.
These switches are summarized as follows: Available in a variety of fixed port configurations with up to 48 1-Gbps access layer ports and 4 Gigabit Ethernet interfaces for uplinks to distribution layer Supports Cisco IOS Supports both Layer 2 and Layer 3 switching Not architected with redundant hardware Cisco Catalyst Family of Switches The Cisco Catalyst family of switches are Layer 2-only switches capable of few Layer 3 features aside from Layer 3 routing.
These features are often found in the access layer in campus networks. Available in a variety of fixed port configurations with up to 48 1-Gbps access layer ports and multiple Gigabit Ethernet uplinks Supports Cisco IOS Supports only Layer 2 switching Not architected with redundant hardware Nexus Family of Switches The Nexus family of switches are the Cisco premier data center switches.
