Description
Starting in exacqVision 7.4, the option to enable Dynamic Host Configuration Protocol (DHCP) services is provided. A DHCP server is used to provide IP addresses to any device on the network that requests address assignment.In exacqVision this feature can be used to more easily assign proper IP addresses to cameras. If multiple DHCP servers are listening for requests on the same network and assigning addresses out, at the very least address collisions are possible and most likely devices on the network will start to become segmented and unable to communicate according to which DHCP server they receive an address from.
For these reasons it is strongly recommended to never use more than one DHCP server on a local area network.
If DHCP is enabled on the exacqVision server and inadvertently connected to a network that already has DHCP services running, steps should be taken to remove the exacqVision DHCP server and reconfigure the devices that received an address from exacqVision.
- The DHCP server should be disabled or the exacqVision recorder should be disconnected from that network. To disable DHCP navigate to the server’s network configuration tab, uncheck the Enable DHCP server checkbox on each NIC and press Apply.
- Reboot any device that received an address from the exacqVision DHCP server. The exacqVision DHCP server will assign addresses in the same network range of exacqVision server NIC it was enabled on. For POE ports on an exacqVision Una server, DHCP is enabled by default and will assign addresses in the 192.168.201-216,2-255 range. After reboot, the device should request and receive a new address from the correct DHCP server.
