Want to do the DHCP server must do in the Super-

A typical LAN means that a core switch with a layer-3 switch is connected to several Branch switches, which may not necessarily have layer-3 switching capabilities ). 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; assume that the vlan names are counter, market, and managing ......

VLAN learning notes VLAN learning notes (1): Why VLAN What is a VLAN? VLAN (Virtual LAN), translated into Chinese as "Virtual LAN ". A lan can be a network composed of a few home computers or an enterprise network composed of hundreds of computers. A

This article mainly introduces the implementation of 802.1Q VLAN protocol in Ethernet switches, as well as some basic content of the 802.1p protocol. For details about the implementation of these two protocols, refer to the relevant information of 802.1Q and 802.1p protocols. I. 802.1Q Protocol 802.1Q Protocol, namely Virtual Bridged Local Area Networks protocol, mainly defines VLAN implementation. Next we

Cisco's VLAN implementations are typically port-centric. The port connected to the node will determine the VLAN on which it resides. There are two ways to assign a port to a VLAN, which is static and dynamic, respectively. The process of forming a static VLAN is the process of assigning a port to a

CCNA Training Course (3) -- Vlan VTP relay single-arm route generation Tree Protocol This is the third day of the CCNA training course. There are many knowledge points on this day, and the experiment content is gradually becoming more complicated.VLAN A vswitch separates the conflict domains and the broadcast domains. A vro separates the conflict domains and the broadcast domains. In a pure exchange network, how do I divide broadcast domains? The answ

Sometimes, the security policy does not allow these same network segments of the virtual machines to communicate with each other, this time you can use the "Private VLAN" function.5.1 Private VLAN IntroductionDedicated

When I participated in the network engineering construction of some companies, I found that most of the company's choice of switches is still in the past, regardless of the enterprise intranet division based on subnets of different departments, generally, you only need to connect all the computers with a 10-ge switch. This requires dedicated enterprise-level traditional routers, such as CISCO 2600 series access routers, to access frame relay before ADSL and other broadband technologies are popul

If we want to communicate between VLANs, we usually use the three layer switch or router sub-interface mode. Linux on the VLAN with Cisco switch relay connection, also can realize their communication with each other.Environment: RHEL 5.2 Minimized installation, physical NIC Eth1, trunk port connected as VLAN switch connected to 2960 GIGABITETHERNET0/1.

I. Features of VLAN VLAN has the following features:Segmented, which can be divided into different network segments by department, function, and project;Flexibility: users who make up a VLAN do not need to consider the physical location of the thing. The same VLAN can also span multiple switches;Security: by separatin

The principle of Super VLAN aggregation, which is no longer difficult to understand, is also mainly used in the network of service providers to solve the shortage of IPv4 address resources. A Super VLAN is also known as VLAN Aggregation. The principle is to set a Super VLAN and multiple Sub VLANs (subvlans) association

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

Virtual lan vlan) not only facilitates network security and prevents network storms, but also improves network operation efficiency and solves many other problems. The popularization of layer-3 switches creates conditions for VLAN applications. In the process of upgrading the network, I also used VLAN technology to solve the problem of network expansion. I.
