Configuration procedure
Configuring the DHCP server
Perform the following tasks on the DHCP server:
1.
Configure a DHCP address pool to dynamically assign IP addresses on subnet 10.11.113.0/24
to the devices.
2.
Specify the IP address of the TFTP server as 10.11.113.19/24.
3.
Specify a template file as the boot file. A template file is named as
networktype.template
, for
example, "vxlan.template".
Creating template files
Create template files and upload them to the TFTP server.
Typically, a template file includes the following contents:
•
System-predefined variables
—Internally used by the system. User-defined variables cannot
be the same as system-predefined variables.
•
User-defined variables
—Defined by the user. User-defined variables include the following:
Basic settings: Local username and password, user role, and so on.
Neutron server settings: IP address of the Neutron server, the username and password for
establishing a connection with the Neutron server, and so on.
•
Software images for upgrade and the URL to download the software images
.
•
Configuration commands
—Include commands independent from the topology (such as LLDP,
NTP, and SNMP) and commands dependent on the topology (such as interfaces and Neutron
settings).
