describe how to combine and deploy the above technologies on CISCO switches for 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

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

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

distribution layer and the access layer, we need to adopt a comprehensive enterprise security policy to protect the entire network and the connected system. In addition, even when a worm occurs, we need to take measures to minimize its impact and protect our network infrastructure to ensure stable network operation. This article describes a unique solution on a Cisco Catalyst Switch to prevent the harm of worms in a very economical, effective, and sc

Overview of LAN Switches The LAN switch has developed into a more expansive space from the traditional hub-and-LAN. For example, Cisco's Catalyst 5000 series LAN switch includes an integrated switched hardware architecture that supports switched 10-mbps Ethernet and 100-mbps Fast Ethernet, with Fast Ethernet, FDDI, switched token Ring, and layer 3rd switching capabilities. This class of switches can provid

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

configuration file config.text, want to recover the password, it is necessary to bypass Config.text this file, first enter the system, then reset the password.Step one, because the Cisco switch Factory settings are no password, so you can restart the switch (unplug the switch and then reconnect) immediately press and hold the "mode" button on the switch. When you see the Configuration Interface display ()650) this.width=650; "src=" http://s3.51cto.co

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

Layer-3 switches of Cisco devices practice communication between different VLANs. Layer-3 switches of Cisco devices practice communication between different VLANs. Cisco device layer-3 Switch implements communication between different VLANs Prepare four PCs, four L2

This document describes how to configure a Cisco switch in two ways, configures some ancillary services, and provides detailed configuration steps and configuration commands. There are two methods to configure a Cisco switch: 1. Console: You can directly configure a Cisco switch. 2. Remote Logon (Telnet): Use the TELNET program to remotely configure a vswitch wit

The previous one to everyone talked about the basic operation of Cisco switches, before the Dragon Boat Festival holiday, the Cisco switch to share a simple configuration and wish you a happy Dragon Boat festival! Ok, to configure the switch, you must first enter the switch's global configuration mode, successfully connecting to the switch and landing successfull

Layer-3 Switch for Cisco switches Although single-arm routing solves the communication problem between different VLANs, it also has its fatal defects: -The single arm itself is the Backbone link of the network, which is easy to form a network bottleneck. -The sub-interface relies on physical interfaces, and the application is not flexible -You need to view the route table for each vlan forwarding, wasting

I believe that many users who use CISCO switches have encountered many problems. Here we have analyzed how to solve common problems of Cisco switches. The data of Cisco switch 03 is a complete database file, the default file name is bam date. dat: Normally, BAM automatically
