In addition to address binding, ARP configurations of Cisco routers are getting more and more attention. Therefore, we will discuss two aspects here. It seems a bit messy, but I hope it will help you. I know that the command for binding the IP address of the cisco router to the mac address is arp IP address, mac address, arpa, but I think there should be a comman

Otherwise, I would be discouraged from using xmodem to transmit 41 MB of IOS. Because I used xmodem to transmit a cisco Switch Failure IOS, it would take more than two megabytes. It took two hours. 41 MB? It can ta

This article describes how to configure a vswitch for a CISCO 3550 router and how to configure access control for a MAC address. In network management, users often encounter this situation: some users violate management regulations and modify their own IP addresses without permission to access restricted resources. Such behavior not only undermines information security rules, but may also cause network comm

This article mainly uses an example to explain in detail how to solve the packet loss problem caused by CISCO router faults? The following article gives me a detailed answer.
