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

For details about how to set the default mode of layer-3 Switch gateway, recently, many friends have been paying attention to the setting of switch gateway. Today, let's have a deep understanding of the techniques for setting the switch gateway! The new experience is waiting

Layer-3 Switch ACLs are used to isolate different VLANs. Create three VLANs: vlan10 vlan20 vlan30 www.2cto.com PC1 PC3 vlan10 PC2 PC4 vlan20 PC5 vlan30Vlan10 vlan20 vlan30 cannot communicate with each other but can access the Internet Pc1: 172.16.10.2 pc2: 172.16.20.2 pc3: 172.16.10.3 pc4: 172.16.20.3 pc5: 172.16.30.2 configure R1Int f0/0Ip add 192.168.1.2 255.25

The contact with the vswitch has been around for a while, and you may find that some content is getting confused. For example, if the vswitch configures the default gateway, the specific configuration commands are quite familiar, but now I don't quite understand why I want to complete the switch gateway settings. I also found some information on the Internet, some for remote access to the switch, and some f

Enable // enter private Mode Configure terminal // enter global Mode Service password-encryption // encrypt the password Hostname Catalyst 3550-12T1 // define the name for the layer-3 Switch Enable password 123456. // enable password Enable secret 654321 // The encryption password of enable (it should be garbled, not 654321) Ip subnet-zero // allow all 0 subnets

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

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

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

Today, I am doing a big internship in hcna experiment. I am based on a very full network system. The center switch is Huawei 3500, followed by two 3026 S, and uplinked to a vro, the route configuration is complete. on the Intranet, I have made two network segments, vlan20 (192.168.2.0), vlan30 (192.168.3.0), and The vro Intranet interface is 192.168.1.1, which is connected to E0/1 of 3500, e0/1 belongs to vlan10, And the IP address is 192.168.1.2. 350

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_A
