DHCP on the OnBoard
26
AlterPath OnBoard Administrator’s Guide
Note:
IP addresses assigned to connected devices must remain constant over
time because each device is assigned an IP address as part of its configuration
on the OnBoard. For that reason, the OnBoard DHCP server should not be
used to provide dynamic IP addresses to devices.
The ability of DHCP to supply fixed addresses can be used to implement the
addressing scheme for connected devices, which is described in the following
sections of this manual:
•
“Preparing an Addressing Scheme” on page 55
•
“Understanding Address Configuration for Connected Devices” on page
336).
The OnBoard administrator can enable the DHCP server and assign IP
addresses to devices by logging into the OnBoard command line as root and
manually editing the
/etc/dhcpd.conf
file and performing other steps
described under “Configuring the DHCP Server” on page 26.
Considerations When Deciding Whether to Use
DHCP to Configure Device Addresses
Before deciding whether to use the DHCP server to configure addresses for
connected devices, the OnBoard administrator should understand the
available options for assigning IP addresses to connected devices, which are
described in “Understanding Address Configuration for Connected Devices”
on page 336.
Configuring the DHCP Server
To enable DHCP to configure IP address for connected devices, the
administrator must perform DHCP configuration manually. The root user logs
into the OnBoard command line and does the following steps.
•
Enables the
dhcpd
by editing
/etc/dhcpd.sh
.
•
Makes the appropriate configuration changes and specifies fixed
addresses for all devices in the
/etc/dhcpd.con
f file.
•
Saves the configuration file changes in the firmware using the
saveconf
command.
•
Reboots or restarts the
dhcpd
service manually.
