Table 8-1. BootP/DHCP/AutoIP options

Options

Bit

Value

AutoIP 0 1

DHCP 1 2

BootP 2 4

For example, if the third octet is 0.0.5.0, the AutoIP and BootP options are disabled; only
DHCP is enabled. (The value 5 results from adding the binary equivalents of 0 and 2.)
This is the most common setting when using DHCP.

Set Gateway IP Address

The gateway address, or router, allows communication to other LAN segments. The
gateway address should be the IP address of the router connected to the same LAN
segment as the unit. The gateway address must be within the local network. The default
setting is N (No), meaning the gateway address has not been set. To set the gateway
address, type Y and enter the address.

Set Gateway IP Address (N) ? Y
Gateway IP addr ((000) (000) (000) (000)_

Netmask: Number of Bits for Host Part

A netmask defines the number of bits taken from the IP address that are assigned for the
host part.

Netmask: Number of Bits for Host Part (0=default) (0) _

Note:

Class A: 24 bits; Class B: 16 bits; Class C: 8 bits

The unit prompts for the number of host bits to be entered, then calculates the netmask,
which appears in standard decimal-dot notation (for example, 255.255.255.0) when the
saved parameters display.
