C: DHCP Support and APIPA

54 Verint Video Solutions

At startup, an edge device searches for a valid IP network

configuration. The device requires this configuration prior to

starting its functions. The network configuration for Nextiva

devices consists of:

 An IP address

 A subnet mask

 A gateway

The device first looks in its local memory. If no configuration is

found, it tries to contact a DHCP server. If DHCP configuration

fails—if the device does not find a server or if it cannot get a

configuration from it within one minute—the device assigns

itself temporary network settings based on the APIPA

addressing scheme. This scheme allows a device to find a

unique IP address until it receives a complete network

configuration, either manually or from a DHCP server.

A device in APIPA mode does not reside on the same subnet as

the other devices on the IP network; therefore, it may not be

able to see them or be visible to them. Devices use the

following temporary APIPA configuration:

 IP address: 169.254. *. *

 Subnet mask: 255.255.0.0

 Gateway: 169.254. *. *

The *. * portion is based on the MAC address of the device.

A device is in APIPA mode:

 The first time it boots up

 After receiving a duplicate IP address

 After a factory reset

 When the DHCP server does not have any available IP

addresses

DHCP configuration is automatically disabled:

 After a firmware upgrade

 After a factory reset
