4. DHCP configuration
Although the Static IP configuration is relatively straightforward to configure, it requires manual 
configuration of each device; a lengthy task if there are a large number of devices to configure.
The Authentication Devices are able to use DHCP to automatically configure the IP Address, subnet 
mask and default gateway. Also if configured on the DHCP server, the DCE server address can also be 
used (see Option 230 below).
DHCP Negotiation fails
If the terminal fails to negotiate with the DHCP server then the IP settings of the Authentication 
Device are set to:
1.
Terminal IP Address = 192.168.2.1 (hard-coded)
2.
Terminal mask = 255.255.0.0 (hard-coded)
3.
Gateway IP Address as stored in the EEPROM
4.
Server IP Address as stored in the EEPROM
If you have multiple Authentication Devices and DHCP fails, all device IP Address are set to the same 
address (192.168.2.1). 
DHCP Negotiation successful
On successful negotiation, the standard IP address values set (IP address, Mask and Gateway) will be 
used as returned by the DHCP server. 
Note:
Values returned by the DHCP server are NOT stored in the EEPROM.
Option 230 present
The Administrator can set option 230 on the DHCP server to allow for the configuration of the server 
field on the Authentication Device.
EQ;A;<DCE Server IP address>
Where the <DCE Server IP address> is the IP address of the server specified in standard 4 octet form, 
e.g. 192.168.1.23
If the parsing of the string is successful the server IP address will be set to the IP address as specified 
however if the parsing of the option fails for whatever reason the server IP address is set to 0.0.0.0. A 
server IP address of 0.0.0.0 will cause the Authentication Device to issue a broadcast bootp request. For 
details, see 
If option 230 is present but is not a Secure Access value, (i.e. used by some other application), the 
server IP Address is set to 0.0.0.0 which causes a broadcast bootp to be issued.
