routing protocols to generate route tables, and running ARP to parse IP addresses; set the cache IP Forwarding Table item. As a basic network, the IP network is evolving into a multi-service network. Therefore, network devices must provide a data operation platform for different policies. In the smart architecture of the three-tier vswitch in the harbor, each data packet can be processed according to the policy through a fast filter engine. 2. layer-

Its VLAN configuration only affects itself.The switch is in Server mode by default.4) create a VLAN. By default, the switch only has VLAN 1. You can use co

The processing of layer-3 data packets by the Gigabit route switch technology, I insist on writing notes every day. Record your experiences and put more time into your career. In the traditional sense, only the device that processes Layer 2 Data Forwarding is called a switch

Case:There are two PCs at the front-end. After Windows 7 is started and the password is entered, the desktop file cannot be displayed (the desktop file is roaming on the win2008r2 server). In the lower-right corner of the screen, the Network Disk cannot be accessed. Refresh the desktop file.Analysis:The Network Disk prompts that it cannot be accessed because of two reasons. I. Hardware problems. Here the hardware mainly refers to the network. 2. software problems. There is no third-party softwar

Generally, a default route is set for all hosts in the LAN to specify the def

[Background description] The company has an internal DI-604LB + Broadband Router and a layer-3 switch. To prevent broadcast storms in the network, the Administrator has created three VLANs on the layer-3 switch. The company uses D

802.1p network services: Different Levels of gold, silver, and bronze services can be implemented based on different payment options, so as to ensure the services of high-priority users as much as possible. Supports the network layer-3 DiffServ service: it provides packet priority tag and priority differentiation processing. The above intelligent services can solve the problem of distribution efficiency an

The h3c layer-3 Switch acl is an example of a new library that can only access the electronic reading room, and cannot access other hosts on the Intranet, so as to avoid security impact. the IP address of the On-Internet www.2cto.com electronic reading room is not opened to 10.0.1.9, the new library plans to divide vlan 11, network segment 10.1.11.0/25, and vlan-

How to communicate with different vlan segments of a layer-3 switch can be achieved through the layer-3 function of the layer-3 Switch, that

Layer-3 egress connection to the internal port of the firewall It is recommended that layer-3 core switches use VLAN1 to connect to the firewall's internal port. The Intranet access to the Internet may be slow due to IP redirection !! The specific examples and solutions are as follows: The core of a certain Enterprise

Idea: Configure The VTP host and client, enable IP routing, and divide VLAN -----> define IP addresses for each VLAN port, and enable trunk ------> enable DHCP on The vtp server, and define IP-pool, set different CIDR blocks to VLAN interface IP addresses as gateways ------> Add ports to corresponding VLANs -------> set management IP addresses and passwords of vswitches 650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M02/4C/42/wKiom1Q6Ms_AiVU2AAH5SP-f5do600.jpg "Title =" Capture 2.jp
