Auto Config Overview Auto Config is a software feature that automatically configures a switch when the device is initialized and no configuration file is found on the switch. Auto Config is accomplished in three phases: 1 Assignment (configuration) of an IP address for the device 2 Assignment of a TFTP server 3 Obtaining a configuration file for the device from the TFTP server Functional Description The Auto Config feature initiates when a switch is turned on and the startup-config file is not found. Auto Config is successful when a configuration file is downloaded to the switch from a TFTP server. The Auto Config process requires DHCP to be enabled by default. NOTE: The downloaded configuration file is not automatically saved to startup-config. An administrator must explicitly issue a save request in order to save the configuration. The Auto Config process depends upon the configuration of other devices in the network, including: • DHCP or BOOTP server • TFTP server • DNS server (if necessary) IP Address Assignment If BOOTP or DHCP is enabled on the switch and an IP address has not been assigned, the switch issues requests for an IP address assignment. The behavior of BOOTP or DHCP with respect to IP address assignment is unchanged by the addition of the Auto Config feature. That is, the following information returned from the server is recognized: • IP address (yiaddr) and subnet mask (option 1) to be assigned to the switch • IP address of a default gateway (option 3), if needed for IP communication Utility 151

This section describes the Auto Config commands.
Auto Config
Overview
Auto Config is a software feature that automatically configures a switch when the device is
initialized and no configuration file is found on the switch. Auto Config is accomplished in three
phases:
1
Assignment (configuration) of an IP address for the device
2
Assignment of a TFTP server
3
Obtaining a configuration file for the device from the TFTP server
Functional Description
The Auto Config feature initiates when a switch is turned on and the startup-config file is not found.
Auto Config is successful when a configuration file is downloaded to the switch from a TFTP server.
The Auto Config process requires DHCP to be enabled by default.
NOTE:
The downloaded configuration file is not automatically saved to startup-config. An administrator must
explicitly issue a save request in order to save the configuration.
The Auto Config process depends upon the configuration of other devices in the network, including:
•
DHCP or BOOTP server
•
TFTP server
•
DNS server (if necessary)
IP Address Assignment
If BOOTP or DHCP is enabled on the switch and an IP address has not been assigned, the switch
issues requests for an IP address assignment. The behavior of BOOTP or DHCP with respect to IP
address assignment is unchanged by the addition of the Auto Config feature. That is, the following
information returned from the server is recognized:
•
IP address (yiaddr) and subnet mask (option 1) to be assigned to the switch
•
IP address of a default gateway (option 3), if needed for IP communication
