takes more time to set Intel vswitches. VTP protocol is not supported on Huawei 8016 devices, VTP protocol is supported on other devices 2026 and 8016, and VLAN1 cannot be configured on, therefore, the network segment of the network management device must be adjusted to other VLANs other than vlan1. in this way, the management VLAN of the TRUNK port should also be changed. CISCO uses the native vlan command, While Huawei uses the default vlan command

Cisco PT Simulation Experiment (5) port aggregation configuration for switchesExperimental Purpose :Understanding Port Aggregation FundamentalsMaster the configuration method of general switch port aggregationExperimental Background : The company's finance department and the sales department of the PC through 2 switches to communicate frequently, in order to improve the bandwidth between links, to ensure th

It's classic. I use it.DeploymentsThe deployments in this document were implemented in an isolated lab environment. the deployments were cleared by issuing the write erase command on the routers, and the clear config all command on the switches to ensure that all devices have a default configuration. make sure you understand the potential impact of any configuration or command on your network before using it.Catalyst 6500 SwitchNote: The following scr

the above technologies on CISCO switches to address typical Layer 2 attacks and spoofing, to prevent man-in-the-middle attacks, MAC/CAM attacks, DHCP attacks, and address spoofing in the exchange environment, more importantly, address management can be simplified through the deployment of the above technologies, track user IP addresses and corresponding switch ports directly to prevent IP address conflicts

Switch Stack-ports displays full port information for the stack switchStacking common, at present in some financial, logistics enterprises are very common, and the other side of the enterprise is not bad money, as long as the program is reasonable, the budget cost is not very small, so here again to emphasize the professional quality of the network workers have been seasoned pre-sales program capabilities.Think of learning as a living habit.-----------is shared by a network of two-tier operator

Q: Are there any simple tools and methods? Do a script, automatically execute on a script in N-around Cisco switches, and then return the results? Method One, the switch configuration file download, modified and uploaded to the n-switch. Then restart or copy start run. Method Two, under Windows to build a bat file, the contents and you telnet to the switch to modify the command used when the same, but the

To prevent IP address theft or employee IP address tampering in a Cisco switch, you can take the following measures: binding an IP address to a MAC address and binding an IP address to a vswitch port. 1. Check the port through IP Address Check the MAC address first, and then check the port based on the MAC address: Bangonglou3 # Show ARP | include 208.41 or show Mac-address-table to view the IP-Mac table of the entire port Internet 10.138.208.41 4 00
