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

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

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 ......

Objective Docker as the hottest lightweight container technology at present, there are many commendable features, such as Docker mirroring management. However, Docker also has many imperfect places, the network aspect is the Docker relatively weak part. Therefore, it is necessary for us to have an in-depth understanding of Docker's network knowledge to meet the higher network requirements. Docker Network mode selection At present, many articles have introduced the network model of Docker, but

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

Fix after "Go" testSuccessfully let IVM run a number of VLANs, add a can carry multiple Vlanid network card, Nativevlan is the compromise method of transformation, if not like this method, with---Delete multi-vlan Nic method, in general, Lpar can only and IVM in the same network segment, I have a study, Success has allowed IVM to run multiple VLANs. The steps are as follows: first, change the blade's built-in switch settings to find the appropriate in

A typical LAN is to connect a core switch with a layer-3 Switch to several Branch switches (not necessarily with layer-3 switching ).

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

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

, reducing network complexity and improving server management capabilities and large-scale scalability. Each UCS rack server is equipped with a VIF interface card that provides two Gigabit Ethernet interfaces. using Cisco Network virtualization technology, it provides both management network interfaces and operating system network interfaces. FI is the old version of 6120, which is inconsistent with the new server version. Therefore, you need to set all versions to the latest version, for exampl

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

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

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

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
