Simply put: Layer-1 switchOnly physical layer protocols are supported (one phone-controlled switch can be called ???)L2 SwitchSupports physical layer and data link layer protocols, such as Ethernet switches.L3 SwitchSupports physical
5012. The value of 2nd bits is 0 ~ 4 indicates that it is a layer-2 switch.
3550. The fifth digit is 5 ~ 9 indicates that it is a layer-3 switch.

of using Server Load balancer to improve the scalability, availability, and manageability of Server clusters. This chapter mainly discusses the deployment of Server Load balancer and several solutions for deploying Server Load balancer in the existing network. We will also discuss how to design highly available solutions to implement fault tolerance for different network components throughout the network, including Load balancer.
Before discussing the network structure, we need to understa
Performance Tests on layer-2 and layer-3 vswitches with 24 ports and all-gigabit vswitches have encountered many problems recently. Experts have said that QoS ensures port congestion, high-priority data is processed first. It makes sense to improve the utilization of 24 fully-gigabit switches with insufficient bandwidth.
Lan exchange technology can also be called layer-2 Switch Exchange Technology, the content mainly includes the working principle of Layer 2 switching, network loops, and how to use the Spanning-Tree Protocol to solve Network loops, VLANs, and VTP technologies, this article m
Lab objectives:1. Master the configuration of the switch Tag VLAN;2. master the basic configuration methods of layer-3 switches;3. Master how to configure VLAN routing for layer-3 switches;4. layer-3 switches are used to implement VLAN visibility and mutual communication;Tec
Two-layer switching technology is a mature development, two-layer switch is a data link layer device, can identify the Mac in the packet
Address information, forwarding based on MAC addresses, and recording these MAC addresses with corresponding ports in one of their own.

Today, the tutor told me about the company's network topology, related to the switch, the basic concept of routers and principles, I am not very clear, so on the internet to learn the information to learn a bit, and then feel that this article is good, so it reproduced, but I reproduced not the original text, and did not attach the original link.
Here I posted a link to my reprinted article: http://blog.csdn.net/herostarone/article/details/8256235
Many SME internal network structures are simple, with only one switch connecting all employees and servers together and then accessing the Internet through fiber optics. Of course, in order to ensure the security of some hosts and split the internal broadcast packet to improve the network transmission speed, take such as partition VLAN, the allocation of different subnets to achieve. By partitioning VLANs, clients on different ports on the same
Two-tier switch:The second layer switching technology is more mature, two layer switch is a data link layer device, can identify the MAC address information in the packet, according to the MAC address to forward, and these MAC addresses and corresponding ports recorded in their own internal table of addresses. Specific
transmission and commerce far exceeds the improvement of computer processing power. Offloading content to a web switch balances the entire site's infrastructure.
------------------Layer 3 switch is to lead the switch by feature!! The 2-tier is based on MAC address access!--
Two-layer switching technology is a mature development, two-layer switch is a data link layer device, can identify the MAC address information in the packet, according to the MAC address forwarding, and the MAC
The layer-3 switch you know works like this. It works like a layer-3 switch.
Why do we say that the L3 forwarding performance of a layer-3 switch is much higher than that of a router? Sometimes it is mentioned in many books that
