Chapter 3 Configuring the Switch for the First Time
Configuring DHCP-Based Autoconfiguration
If the switch cannot read the network-confg, cisconet.cfg, or the hostname file, it reads the
router-confg file. If the switch cannot read the router-confg file, it reads the ciscortr.cfg file.
Note
The switch broadcasts TFTP server requests provided that one of these conditions is met: the TFTP
server is not obtained from the DHCP replies; all attempts to read the configuration file through unicast
transmissions fail; or the TFTP server name cannot be resolved to an IP address.
Example Configuration
Figure 3-3 shows a network example for retrieving IP information using DHCP-based autoconfiguration.

feature running on your switch.
