30InRow RD 100-Series and InRow RD 200-Series User’s Guide
DHCP response options
Each valid DHCP response contains options that provide the TCP/IP settings that the InRow RD needs to
operate on a network, and other information that affects the operation of the InRow RD.
Setting Description
Manual The IP address, subnet mask, and default gateway must be configured manually. Click Next>>,
and enter the new values.
BOOTP A BOOTP server provides the TCP/IP settings. At 32-second intervals, the InRow RD requests
network assignment from any BOOTP server:
• If it receives a valid response, it starts the network services.
• If it finds a BOOTP server, but a request to that server fails or times out, the InRow RD stops
requesting network settings until it is restarted.
• By default, if previously configured network settings exist, and it receives no valid response to
five requests (the original and four retries), it uses the previously configured settings so that it
remains accessible.
Click Next>> to access the BOOTP Configuration page to change the number of retries or the
action to take if all retries fail
1
:
• Maximum retries: Enter the number of retries that will occur when no valid response is
received, or zero (0) for an unlimited number of retries.
• If retries fail: Select Use prior settings (the default) or Stop BOOTP request.
DHCP At 32-second intervals, the InRow RD requests network assignment from any DHCP server. By
default, the number of retries is unlimited.
• If it receives a valid response, by default it requires the APC cookie from the DHCP server in
order to accept the lease and start the network services.
• If it finds a DHCP server, but the request to that server fails or times out, it stops requesting
network settings until it is restarted.
To change these values, click Next>> for the DHCP Configuration page
1
:
• Require vendor specific cookie to accept DHCP Address: Disable or enable the requirement
that the DHCP server provide the APC cookie.
• Maximum retries: Enter the number of retries that will occur when no valid response is
received, or zero (0) for an unlimited number of retries.
DHCP &
BOOTP
The default setting. The InRow RD tries to obtain its TCP/IP settings from a BOOTP server first,
and then, if it cannot discover a BOOTP server, from a DHCP server. If it obtains its TCP/IP
settings from either server, it switches this setting to BOOTP or DHCP, depending on the type of
server that supplied the TCP/IP settings to the InRow RD.
Click Next>> to configure the same settings that are on the BOOTP Configuration and DHCP
Configuration pages
1
and to specify that the DHCP and BOOTP setting be retained after either
type of server provides the TCP/IP values.
1. The default values for these three settings on the configuration pages generally do not need to be changed:
•Vendor Class: APC
•Client ID: The MAC address of the InRow RD, which uniquely identifies it on the local area network (LAN)
•User Class: The name of the application firmware module
