Performing Switch Setup Configuration
Information About Performing Switch Setup Configuration
If the relay device is a Cisco router, enable IP routing (ip routing global configuration command), and configure helper
addresses by using the ip helper-address interface configuration command.
For example, in Figure 3 on page 66, configure the router interfaces as follows:
On interface 10.0.0.2:
router(config-if)# ip helper-address 20.0.0.2
router(config-if)# ip helper-address 20.0.0.3
router(config-if)# ip helper-address 20.0.0.4
On interface 20.0.0.1:
router(config-if)# ip helper-address 10.0.0.1

How to Obtain Configuration Files
Depending on the availability of the IP address and the configuration filename in the DHCP reserved lease, the switch
obtains its configuration information in these ways:
 The IP address and the configuration filename is reserved for the switch and provided in the DHCP reply (one-file
read method).
The switch receives its IP address, subnet mask, TFTP server address, and the configuration filename from the DHCP
server. The switch sends a unicast message to the TFTP server to retrieve the named configuration file from the base
directory of the server and upon receipt, it completes its boot-up process.
 The IP address and the configuration filename is reserved for the switch, but the TFTP server address is not provided
in the DHCP reply (one-file read method).
The switch receives its IP address, subnet mask, and the configuration filename from the DHCP server. The switch
sends a broadcast message to a TFTP server to retrieve the named configuration file from the base directory of the
server, and upon receipt, it completes its boot-up process.
 Only the IP address is reserved for the switch and provided in the DHCP reply. The configuration filename is not
provided (two-file read method).
The switch receives its IP address, subnet mask, and the TFTP server address from the DHCP server. The switch
sends a unicast message to the TFTP server to retrieve the network-confg or cisconet.cfg default configuration file.
(If the network-confg file cannot be read, the switch reads the cisconet.cfg file.)
