Using automatic configuration
With the automatic configuration feature, the device can automatically obtain a set of configuration
settings from servers when it starts up without a configuration file. This feature simplifies network
configuration and maintenance.
In this chapter, "MSR2000" refers to MSR2003. "MSR3000" collectively refers to MSR3012, MSR3024,
MSR3044, MSR3064. "MSR4000" collectively refers to MSR4060 and MSR4080.
Understanding server-based automatic
configuration
The automatic configuration feature requires the cooperation of the following servers: a DHCP server, a
TFTP server, and a DNS server, as shown in Figure 51.
Figure 51 Typical server-based automatic configuration network diagram
When the device is powered on without a configuration file, it automatically starts the automatic
configuration process to try to obtain a set of configuration settings. If one attempt fails, the device waits
30 seconds, and then automatically starts the process again for another try. The device continues to
make attempts until it gets a set of configuration settings or it is powered off.
Overall automatic configuration process
As shown in Figure 52, the automatic configuration process includes the following steps:
1. The device selects an interface for automatic configuration. For more information, see "Interface
sele
ction process."
2. After finding an interface, the device enables the DHCP client on the interface and tries to obtain
parameters for automatic configuration.
Parameters for automatic configuration might include:
