Cisco switch security common traffic control and anti-DDoS problems. Recently, cisco switch security has been favored by many friends. Let's have a deep understanding of cisco switch security solutions today! Traffic control, anti

MAC address on the switch. In the middle of a Cisco switching network, how do I find out which port of the switch is connected to the IP address of a machine? The most convenient and quick way is to use the User tracking function of the CiscoWorks 2000 LMS network management software. The graphical interface is clear at a glance. If you do not have this software

The frame format of VLAN relay is divided into two types: ISL (Inter-Switch Link, connection between switches) and 802.1Q. The former is the protocol unique to the

In the real world or laboratory environment, Cisco IOS test commands are very useful and powerful commands. Learn the basic usage of this command and learn a few useful sub-commands. This is not surprising if you have never used the Cisco IOS test command. I have met many ne

In fact, Cisco does not take a special advantage in the low-end switch market, because 3Com, Dlink and other companies have better performance and price ratios. The 1900 vswitch is a typical low-end product for desktop computer access at the end of the network. It pro

want to initialize the switch, you need to enter the Privileged EXEC mode. Enter setup in the command prompt symbol to start the initialization operation.The Privileged EXEC mode is introduced just now. In this case, we need to talk about several modes of machine change. Different modes can execute different operation commands. First, we need to talk about two basic modes.For the sake of security,

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
