At present, the demand for Routing Switching equipment is very high in the market, especially in enterprises. It can be seen from the data that the performance of Routing Switching equipment is also gradually improving. The vro and vswitch password recovery methods must be mastered by the network administrator. These contents are displayed in the CCNA courses. However, from the description of this user, we can see that the model of the routing switch device used by your company is not CISCO, so

Recently, the organization decided to upgrade the network device. All the originally used 3Com switches, and all the computers were assigned to two VLANs. Except some computers use fixed IP addresses, other computers obtain the address through a DHCP server. After the network is upgraded, the network center router remains unchanged. Most access-level switches are switched to Cisco Catayst 3550 or Cisco Catayst 2950, but the following situations occur

divided into two types, which are called analysis ports in the CATALYST family ).1. Catalyst 2900XL/3500XL/2950 series switch port monitoring configuration (based on CLI)Run the following command to configure a port listener: Port monitor For example, F0/1 and F0/2 and F0/5 belong to the same VLAN1 and F0/1 Listen to ports F0/2 and F0/5: interface FastEthernet0/1port monitor FastEthernet0/2port monitor FastEthernet0/5port monitor VLAN1 2.

meet the needs of netizens for surfing and playing games. Therefore, two lines are required to increase bandwidth; on the other hand, network interruption will have a great negative impact on the operation of Internet cafes, so line backup is also very important. The dual-WAN port not only increases bandwidth, but also achieves line backup, which meets the double-layer requirements of Internet cafes. For small and medium-sized enterprises, the same principle is true. On the one hand, increasing

The core route switch is a new generation switch product. Here we mainly introduce eight main features of the core route switch, quidway S8500 series 10-Gigabit core route switch is a new generation high-performance 10-Gigabit core route switch developed by Huawei 3Com. It can be widely used in the core layer of the E-government network, the core layer of the campus network and the Education Metropolitan Area Network, the core layer of the campus netw

with you for ease of use? The answer is yes. Now I will introduce you to a Linux firewall that can be installed on a general floppy disk. The Linux Firewall named floppyfw can be stored in a general floppy disk and run independently in RAM memory. Use it to start the computer, use ipchains to filter out useless IP packets, and use it to configure IP disguised IP masquerade), monitor the port, you can use a host to remotely control computers in other networks. Floppyfw is very powerful, but it r

big, the centralized cabling solution was adopted, with 5 types of lines, 125 mbps bandwidth and information points. The vswitch uses 12-port 3Com 3c5092a 10/100 M Adaptive device, and the shared hub uses several 3Com 16-port hubs. Cisco 3600 is used as the router and four Wide Area Network ports are connected.Remote grass-roots units and boxes are deployed in the dial-up mode. In the future, Frame Relay F

like an overlay. No matter where the data comes from and where it goes, it can be passed through at a high speed at the same time. Currently, the mainstream switch brands on the market include Cisco, 3Com, Huawei, Digital China, all-round, Shida, and TP-Link, these manufacturers' 8-port 10/100 M switches have hundreds of Yuan of products and thousands of yuan of products. The 24-port 10/100/6000 m switch with the most application in the network can b

In the "configuration" box, select a configuration consistent with your Nic and the specified operating system. For example, for a 3Com EtherLink III Nic, select DOS6.22 3Com EtherLink iii accton EN166x Nic and select DOS6.22 Novell NE2000.3) create a remote startup database record for the

To meet the needs of different users, there are also a variety of interfaces for this type of wireless network card, such as Type II interface Benq AWL100 Wireless lan pc card, Sony pcw150; USB interface 3COM 3CRSHPW696-CH, AboveCable ACAP2010-11/USB and PCMCIA Interface TP-LINK TL-WN210 +, D-Link DWL-650 +, there are also wireless NICs Intel WPCI2011B and

small and medium-sized enterprises. As the prices of low-end switches keep falling, the price of Yuan is becoming more and more selective. Today, the shopping guide of small series recommends several yuan enterprise switches. Huawei 3Com S1026T reference price: 950 yuan The S1026T is an iron case with a length of 330mm, a width of 230mm, and a thickness of 43mm. It can be placed on a 1U standard rack. The S1026T Ethernet switch is closely arranged on

If your network card is not supported, you can compare it with the wireless network card model supported by BT4. The following wireless network interfaces are sorted by interface type.

Linux adds drivers that are not included in the system, it is difficult to find the driver for this version. ?? External Device Driver support problems The external devices here mainly refer to the NIC, array card or scsicard issues, which will be discussed separately. The driver for the NIC mainly supports the core chip of the NIC. Not all NICs have drivers in Linux. There are many poor chip manufacturers who do not want the chip to be used in Linux when developing it. Therefore, they only wa

modification. However, some NICs do not have this option. Do not worry. You can update the NIC Driver first.ProgramTry it. This option will usually appear after the driver is updated. But there are still some special cases. No matter how you modify it, there is no such option. What should we do? Next, let's look at the following method as omnipotent! Registry Modification MethodStep 2: Click Start, select Run, and type regedit to bring up the registry. In step 3, find driverdesc in the prima

about flexibility later. 　　 Networking options: This mainly applies to TCP/IP Settings. Generally, you can use the default settings on the machine. If you want to use a firewall You can choose a route or something. I have never selected it. I dare not talk about it like PP; 　　 SCSI support: I don't have a SCSI device, so I don't select either of them. Do you have one? Make all you want into modules, In this way, the kernel will be relatively small. For example, 16.8 selects "AIC7xxx" in "low-le

China's router technology development is very rapid, so I studied the router technology in the router platform based on several POS access methods in the actual application, here to share with you, hope for everyone useful. Under the situation of further encouraging card consumption and popularizing the financial POS business, there are many problems in our financial system, such as high cost of POS access equipment, low access density, special equipment and inconvenient maintenance.
