Automatic configuration Automatic configuration overview Aut omatic conf igurati on enables a dev ice w ithout an y configur ation file to a utomatically obtain and ex ecut e a configur ation f ile during startup .
How automatic configuration works Aut omatic conf igurati on w orks in the fo llo wing manner : 1. During startup, the device sets the first up interfa c e (if up Layer 2 Ethernet inter faces are available, the VLAN interface of the default VLAN of the Ethernet interfa ces is selected as the first up interface.
Using DHCP to obtain an IP address and other configuration information Address acquisition process As mentioned be for e, a dev ice sets the f irst up interface as the DHCP c lient dur ing star tup .
administrator can T elnet to each de vi ce to perfor m spec ifi c configur ations (fo r exa mple, conf igur e the IP addres s of each interf ace) . • If dev ices u se differ ent confi guration f iles, y ou need to confi gure static addr ess pools to ensur e that each de vice can get a f ix ed IP address and a spec ifi c configur ation file .
Obtaining the configurati on file Figure 51 Obtain the configuration file Is the configura tio n fil e contained in the DHCP response? Obtain the n etwork intermediate fi le Search the domain name cor.
NOTE: After broadcasting a TFTP request, the device selects the TFTP server that responds first to obtain the configuration file. If the requested configuration fi le does not exist on the TFTP server, the request operation fails, and the device removes the temporary configuration and starts up with factory defaults.
