Automatic DHCP IP Interface Assignment
The user can manually define a DHCP interface in the DHCP IPv4 page.
If the user does not do this, the switch automatically creates a DHCP
interface on the VLAN with the lowest VLAN ID that does not have an IP
address defined on it after boot if both of the following conditions are
fulfilled:
• There is no DHCP IP interface.
• There is a VLAN without an IP address.
Preparations for Using Auto Configuration from a TFTP Server
The Auto-Update/Configuration feature enables configuring the device from
a configuration file found on the TFTP server.
Two methods may be used:
• One-file Read, described in "Auto Configuration (One File Read Method)"
on page 185. This method is used if a configuration file is found on the
TFTP server.
• Multi-file Read, described in "Auto Configuration (Multi File Read
Method)" on page 186. This method is used if a configuration file name is
not found on the DHCP server, or the configuration file is not found on
the TFTP server.
Auto Configuration (One File Read Method)
This method requires the following preparations on the DHCP and TFTP
servers:
• TFTP Server
Place a configuration file, for example config.txt in the main directory.
This file can be created by copying a configuration file from a device.
When the device is booted this becomes the Running configuration file.
• DHCP Server
– Configure the DHCP server with option 67 and the name of the
configuration file on the TFTP server (for example, config.txt).
– Configure the DHCP server with option -20 or 66. This is the IP
address of the TFTP server.
