2.   When the Network Management Card reboots, the BOOTP server provides it with the TCP/IP 

settings. 

– If you specified a bootup file name, the Network Management Card attempts to transfer that 

file from the BOOTP server using TFTP or FTP. The Network Management Card assumes all 
settings specified in the bootup file. 

– If you did not specify a bootup file name, the Network Management Card can be configured 

remotely by using the control console or the Web interface (user name and password are both 
apc, by default).

To create the bootup file, see your BOOTP server documentation.

You can use an RFC2131/RFC2132-compliant DHCP server to configure the TCP/IP settings for 

the Network Management Card. 

This section briefly summarizes the Network Management Card communication with a 
DHCP server. For more detail about how a DHCP server is used to configure the network 
settings for a Network Management Card, see “DHCP Configuration” in the NetworkAIR 
FM DX User’s Guide.

1. A Network Management Card sends out a DHCP request that uses the following to identify itself:

– A Vendor Class Identifier (APC by default)

– A Client Identifier (by default, the MAC address value of the Network Management Card)

– A User Class Identifier (by default, the identification of the application firmware of the 

Network Management Card)

2. A properly configured DHCP server responds with a DHCP offer that includes all of the settings 

that the Network Management Card needs for network communication. The DHCP offer also 
includes the Vendor Specific Information option (DHCP option 43). By default, the Network 
Management Card will ignore DHCP offers that do not encapsulate the APC cookie in the Vendor 
Specific Information option using the following hexadecimal format:

Option 43 = 01 04 31 41 50 43

where 

– the first byte (

01

) is the code

– the second byte (

04

) is the length

– the remaining bytes (

31 41 50 43

) are the APC cookie

See your DHCP server documentation to add code to the Vendor Specific 
Information option.

To change the control console DHCP Cookie Is setting, use the Advanced option 
in the TCP/IP menu. See “Remote access to the control console” on page 64.

To change the Web interface setting Require vendor specific cookie to accept 
DHCP Address, which is enabled by default, first choose DHCP under the 
TCP/IP Configuration heading by selecting the Administration tab, the 
Network option on the top menu bar, and TCP/IP on the left navigation menu. To 
disable the APC cookie requirement,  click Next to access the DHCP 
Configuration page, and unmark the checkbox "Require vendor specific cookie to 
accept DHCP Address."
