End to end FCoE get breakthrough still need to wait for switch support
VMware has certified an End-to-end FCOE connectivity solution for Cisco and NetApp, but this does not mean that new markets are emerging because core switches still do not support transmission of FCOE information. Only the overhead switch (top-of-rack-switches) (tors) can transmit FCoE inform
Two-layer switch:
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 address and the corresponding port record in their own internal address table.
Specifically as follows:
(1) When the switch receives a
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 as follows:(1) When the switch receives a packet from a port, it reads the source MAC add
What is a fool switch? It is easy to understand the introduction is not to take care of its switch, connected to the network equipment can be used.
With the development of modern society, the modern "lazy person" also more and more, those who light, convenient, easy and labor-saving "lazy people" is more and more modern "lazy people" welcome. Today's switches are increasingly "goofy", such as the Omni-qs-5
The "advanced" usage of the PHP switch judgment statement is detailed in the switch
Only so called "advanced" usage, because I even switch the most basic usage has not mastered, so, the next is actually the basic usage of it!
A switch statement is similar to a series of IF statements that have the same expression. In
Often see network friends in the difference between the switch and router, in fact, if you have used both switch and router friends should know, for everyone, switch and router use the biggest difference is that the router can realize dial-up internet access, and then shared to multiple computers at the same time the Internet, But the
Are you worried about the port mode of the switch? below, I will walk into the switch with you and hold the switch port mode completely. I will use an article with a picture and truth to make you no longer confused.

After entering the configuration page, if this is the first configuration, You need to configure the IP address first, which is mainly for remote configuration later. The IP address configuration method is as follows:
Enter "I" in "Enter Selection:" On the configuration page that appears, and click Enter. The following configuration information is displayed:
The IP Configuration Menu appears.

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 the software of the router is also very powerful and can almost achieve the speed limit forwarding capability. However, it is unlikely
This article introduces the knowledge of switch stack and the principle of switch stack. There are many problems with switch stack on the network. For vswitches of various models, a q A topic about switch stack is provided below. I hope to give all questions about switch st
IntroductionTraditional routers have isolated networks, isolated broadcasts, routing and forwarding, and firewall operations in the network, and as the network continues to evolve, the load of routers is growing rapidly. One of the important reasons is that the VLAN (virtual local area network) technology is widely used in networks because of security and management convenience. VLAN technology can logically isolate different network segments, ports, or even hosts, and the communication between

A Router operates at the network layer, the third layer in the OSI Layer-7 network model. It works by removing the information of the second layer (data link layer) of a packet (including a broadcast packet) received on the Network (called "unpacking "), and view the layer-3 Information (IP address ). Then, the route of the data packet is determined based on the ro
Android slide switch component and android slide Switch
Because Android does not provide components such as slide switches, we need to implement a custom view component to achieve the slide switch effect.
Here is an example code, which includes three classes: switch component view, status listening interface, MainActiv
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. Recently, the price of vswitches has been greatly reduced. Some models of some domestic brands have fallen below RMB, which is almost the same as that of hubs. With the updates of People
Many vswitch users have encountered many problems due to many reasons. Here we mainly analyze the vswitch network faults caused by incorrect Switch location installation. A vswitch is a key connection device in a LAN. It has a large number of vswitches in a LAN. In such a network environment, the administrator needs to reasonably deploy the vswitch based on its performance and characteristics, because your improper deployment will pose hidden risks in

If statements process two branches, the if-else-if structure must be used when processing multiple branches. However, if there are many branches, the more nested if statement layers, the program is not only huge but also difficult to understand. therefore, the C language provides a condition selection statement specifically used to process multi-branch structur

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
