The TCP/IP option on the left navigation menu, selected by default when you choose Network on the
top menu bar, displays the current current IPv4 address, subnet mask, default gateway, MAC address,
and boot mode of the Management Card.
For information on DHCP and DHCP options, see RFC2131 and RFC2132.
Setting Description
Enable Enable or disable IPv4 with this check box.
Manual Configure IPv4 manually by entering the IP address, subnet mask, and default gateway.
BOOTP A BOOTP server provides the TCP/IP settings. At 32-second intervals, the Management Card
requests network assignment from any BOOTP server:
• If the Management Card receives a valid response, it starts the network services.
• If the Management Card finds a BOOTP server, but a request to that server fails or times out, the
Management Card stops requesting network settings until it is restarted.
• By default, if previously configured network settings exist, and the Management Card 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

:
• 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 The default setting. At 32-second intervals, the Management Card requests network assignment
from any DHCP server.
• If the Management Card receives a valid response, it does not (as previously) require the APC
cookie from the DHCP server in order to accept the lease and start the network services.
• If the Management Card finds a DHCP server, but the request to that server fails or times out, it
stops requesting network settings until it is restarted

.
• Require vendor specific cookie to accept DHCP Address: By selecting this check box, you can
require the DHCP server to provide a cookie which supplies information to the Management
Card.

• Vendor Class: APC
• Client ID: The MAC address of the Network Management Card, which uniquely identifies it on the local
