Nextiva S2750e Series User Guide

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

parameters 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 or be visible by the other devices. Devices use

the following temporary APIPA configuration:

 IP address: 169.254.X.Y (where X and Y are based on the last two digits of the MAC

address of the device)

 Subnet mask: 255.255.0.0

 Gateway: 169.254. *. *

A device is in APIPA mode:

 The first time it boots up

 After receiving a duplicate IP address

 After a hardware reset

 When the DHCP server does not have any available IP addresses

 After loading the default parameters

DHCP configuration is automatically disabled after a factory reset.
