cisco 2955 switch

There are still many things worth learning about Cisco switches. Here we mainly introduce the Cisco switch interface mode. In a Cisco switch network, there are four main types of interfaces in the LAN that are ultimately stable: access/trunk/multi/dot1q-tunnel. 1. access: it

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
