Auto Install Configuration
Auto Install is a software feature that provides for the configuration of a switch automatically
when the device is initialized and no configuration file is found on the switch. The downloaded
configuration file is not distributed across a stack. When an administrator saves configuration,
the config file is distributed across a stack.
The Auto Install process requires DHCP to be enabled by default in order for it to be completed.
The downloaded config file is not automatically saved to startup-config. An administrator must
explicitly issue a save request in order to save the configuration. The Auto Install process
depends on the configuration of other devices in the network, including a DHCP or BOOTP
server, a TFTP server and, if necessary, a DNS server.
There are three phases to Auto Install:
1.
Configuration or assignment 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.
Switch 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 Install feature.
That is, the following information returned from the server is recognized.
°
The IP address (yiaddr) and subnet mask (option 1) to be assigned to the switch
°
The IP address of a default gateway (option 3), if needed for IP communication. Some
network configurations require the specification of a default gateway through which some
IP communication can occur. The default gateway is specified by Option 3 of a BOOTP
or DHCP response.
After an IP address is assigned to the switch, if a host name is not already assigned, then
Auto Install issues a DNS request for the corresponding host name. This host name is also
displayed as the CLI prompt the same as if the
hostname
command was used.
