. For example, firewalls have weak anti-lookup capabilities. They only record the security activity status of cisco switches. As a recent smart access point for users, layer-3 switches go deeper into the network base layer than firewalls. In this layer, network control is easier, more effective, and more cost-effective. In the event of civil chaos, it can effectively control the scope of impact and accurately locate the sources of chaos. Therefore, th

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, you can use the following manual analysis method to find the answer: Ex

password to enter the privileged mode, and the original configuration content is retained.Operation steps: 1. Prepare the console cable and connect the Super Terminal. 2. Restart the switch (because 2950 does not have a power switch, you can directly unplug the power cord and connect it back.) 3. Press the MODE key at the start to enter the switch MODE. Note: th
