Layer-3 switches are quite common, so I have studied how to build enterprise VLANs for layer-3 switches. Here I will share with you, hoping they will be useful to you. The emergence of Virtual lan vlan breaks the many inherent concepts of traditional networks, making the network structure flexible, convenient, and free

Since Layer-3 switches can be considered as composed of routers and common switches, You can first try to install some modules with routing functions during assembly, in this way, there is a layer-3 Switch rich in routing functions. Its functions are equally powerful. Recent

a layer-3 test. Take the outstanding layer-3 Switch DGS3308TG of Digital China D-Link as an example. We connect the eight Gigabit ports of the vswitch with the eight Gigabit ports on the IXIA1600 tester. We configure the layer-

Layer-3 egress connection to the internal port of the firewall It is recommended that layer-3 core switches use VLAN1 to connect to the firewall's internal port. The Intranet access to the Internet may be slow due to IP redirectio

In today's society, the most commonly used vro is the number of routers, because it is relatively cheap and its functions are no different from those of vswitches. However, layer-3 vswitches are indeed more powerful than vrouters, then we will study the layer-3 switch. Many

Have you ever thought about manually creating a layer-3 switch? Here we will teach you how to create such a layer-3 switch, which is equally powerful. Recently, the price of vswitches has been greatly reduced. Some models of some

from a group of MAC addresses. GMRP transmits such group information between vswitches on the Internet, so that vswitches can update their filtering information to implement extended service functions. A vswitch has the filtering service and extended filtering service without any configuration. Because the old vswitches, hubs, and routers do not support dynamic multicast address filtering, the corresponding ports connected to them need to be configured with extended filtering. The

Since Layer-3 switches can be considered as composed of routers and common switches, You can first try to install some modules with routing functions during assembly, in this way, there is a layer-3 Switch rich in routing functions. Its functions are equally powerful. Recent

There are many things worth learning about layer-3 router switches. Here we mainly introduce the solutions to soft faults in layer-3 router switches. Two days ago, our company's network was upgraded, and the core device adopted the INTEL550 series L3 route switch. The 500 se

routing. Therefore, poor performance of routers often becomes a network bottleneck. To solve the performance defects of software-based routers, driven by the new ASIC chip technology, the chip function used to process layer-2 data packets in a vswitch is enhanced to the ability to process layer-3 data packets. This Gigabit routing

VLAN based on a layer-3 switch can resolve conflicting domain, broadcast domain, and bandwidth issues for the LAN. VLAN can be divided based on the network layer. There are two solutions: one is divided by Protocol (if there are multiple protocols in the network; the other is based on the network

through the port to a certain range, so as to prevent the bandwidth of the switch from being abused without limit. The traffic control function of the security switch can control abnormal traffic to avoid network congestion. Anti-DDoS Once a company suffers a large-scale distributed denial-of-service attack, it will affect the normal network usage of a large num

switches are Layer 2 network devices. They can understand Layer 2 network protocols, such as MAC addresses. Layer-3 switch technology constantly collects data during operations to create its own address table. This table is quite simple. It mainly indicates the

disadvantages of a vswitch should begin with three aspects: overall architecture, performance, and function. The overall architecture refers to the value of basic performance parameters such as the port density, the maximum rate supported by the port, and the switching capacity of a layer-3

The instance explains VLAN division and configuration issues in layer-3 Switch configurations. vlan division and configuration issues cannot be avoided in layer-3 Switch configurations. Generally, there are four categories, how to

use the H3C3 layer switch code. You can find the layer-3 Switch configuration code on the Internet. If you can help me solve the problem, continue to deliver points. Lt; SwitchA gt; system-view# Creating VLAN100[SwitchA] vlan 100: Ethernet 1/0/1 is allocated to vlan100.[S

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.
