Nowadays, it is common that a company network consists of not only servers and PC, but also IoT devices, printer, IP cameras, and a lot more. Stability would always be the top priority, and IP conflict is one of the causes of unstable connections. In the past, the network administrator may need to take a long time to find conflict sources from the big network.
VigorSwitch supports IP Conflict Prevention (ICP) since firmware version 2.4.0. It helps the administrator to find out the conflicting port and IP and take action quickly. This article introduces ICP and demonstrates how to use it on VigorSwitch.
ICP takes the advantages when there are multiple switches on the network, even if not all the switches support ICP. The edge switch can be other brands that you already have, and ICP would still work partially.
PC4 conflicts PC1: PC4 can't go through core switch, but PC4 still can access other hosts within edge switch.
PC2 conflict PC1: PC2 will be locked. It's because PC1 is configured to have the higher priority of using the IP.
When IP conflict happens, ICP shows the conflict status on the GUI like below, so that the network administrator could be aware of where the problems are.
Quick Start Wizard will be convenient and easy way to set up.
1. In the Quick Start Wizard, first select a port to which DHCP server is connecting.
2. VigorSwitch will conduct a preliminary detection of the environment and show the port type. If the port is incorrect, click on the port to change the port type to the correct one
3. The switch will detect your network, and showing the hosts table. Remember to put the correct information on it.
4. Enable ICP, then ICP will be affected immediately.
NOTE: What is the sequence to enable ICP on different switch layer? We recommend to set the port type first (1-3 step on Wizard), then enable ICP on each layer.
