Switch: instance for VLAN configuration of Cisco L3 switch + L2 Switch

An instance of VLAN configuration for Cisco L3 switches and L2 SwitchesCisco VLAN implementation is usually port-centric. The port connected to the node determines the VLAN in which it resides. There are two ways to allocate a port to a VLAN: Static and Dynamic. The process of creating a static

Layer-3 Switch VLAN/VTP/inter-VLAN routing/DHCP

A typical LAN is to connect a core switch with a layer-3 Switch to several Branch switches (not necessarily with layer-3 switching ). We assume that the core switch name is com, and the Branch switches are par1, par2, and par3 respectively, which are connected to the core switch through the light module of port 1; assu

Two-layer switch when three-layer switch uses one-arm routing to implement VLAN interoperability on layer Two switches

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,

Cisco Cisco switch VLAN configuration Tips

Technical standards for VLANs IEEE 802.1Q was formally promulgated by IEEE Commissioners in June 1999, and the earliest Vlna technology was proposed by Cisco (Cisco) companies in 1996. With the development of the past few years, VLAN technology has been widely used in large and small enterprise networks, becoming the most popular Ethernet LAN technology at present. This article is going to introduce one of the most common

Hua San (H3C) switch operation commands detailed VLAN switch

Programmers are lazy, you know. Ten years of life and death two boundless, write procedures, to the dawn. Thousand lines of code, where the bug is hidden. Even if the line and how, toward the change, Xi heartbroken. Lead a new idea every day, change every day, daily busy. Care without words, only tears thousand lines. Every night the lights are dim, the night is hard to sleep, and overtime. Gossip less, directly on the code: Hua San switch operation

Switch VLAN division Experiment

Basic knowledge of VLAN division experiment: VLAN is short for Virtual Local Area Network (VLAN), which is a logical Network divided on a physical Network. This network corresponds to the L2 network of the ISO model. VLAN division is not limited by the actual physical location of the network port. A

Therefore, the use of VLAN in the initial design of the network can bring great benefits to the future expansion of the network.VLAN partitioning by routers is a cost-effective method in small and medium-sized enterprises. However, VLAN partitioning by routers seriously affects the network performance of enterprises, therefore, layer-3 switches with routing functions are widely used in

H3C Switch series of Super VLAN

First, the generation of Super VLAN backgroundIsolate-user-vlan successfully solved the problem of reducing the number of VLANs, and also realized the sharing of three-layer gateways to some extent. But it also has a problem with MAC address duplication that consumes MAC address table entries, and the technology itself belongs to a two layer VLAN technology.In a
