DHCP

Step 2: Activate and Save.

To activate your new configurations and save them to flash, type:

config write

(This is essentially typing signal_ras hup and saveconf from the normal terminal

prompt.)

DHCP

The DHCP (Dynamic Host Configuration Protocol) Client is available for firmware versions

1.2.x and above. DHCP is a protocol that allows network administrators to assign IP addresses

automatically to network devices. Without DHCP (or a similar protocol like BOOTP), each

device would have to be manually configured. DHCP automatically sends a new IP address to

a connected device when it is moved to another location on the network. DHCP uses the

concept of a fixed time period during which the assigned IP address is valid for the device it

was assigned for. This “lease” time can vary for each device. A short lease time can be used

when there are more devices than available IP numbers. For more information, see RFC 2131.

Parameter Involved and Passed Values

The DHCP client on the Ethernet Interface can be configured in two different ways, depend-

ing on the action the BLACK BOX ® Advanced Console Server should take in case the DHCP

Server does not answer the IP address request:

1. No action is taken and no IP address is assigned to the Ethernet Interface (most common

configuration):

• Set the global parameter conf.dhcp_client to 1.

Tip. You can configure all the parameters for a serial port in one line:

config configure line <serial port number> tty <string>

conf nfsdb <string> db <number> dbmode <string> dbmenu

<number> dbtimestamp <number> syslogdb <number>
