Dell PowerConnect 3548 User Manual

56 Configuring PowerConnect 3524/P and 3548/P
Receiving an IP Address From a BOOTP Server
The standard BOOTP protocol is supported and enables the device to automatically download its IP host
configuration from any standard BOOTP server in the network. In this case, the device acts as a BOOTP
client.
To retrieve an IP address from a BOOTP server:
1
Select and connect any port to a BOOTP server or subnet containing such a server, to retrieve the
IP address.
2 At the system prompt, enter the delete startup configuration command to delete the Startup
Configuration from flash.
The device reboots with no configuration and in 60 seconds starts sending BOOTP requests.
The device receives the IP address automatically.
NOTE: When the device reboot begins, any input at the ASCII terminal or keyboard automatically cancels the
BOOTP process before completion and the device does not recieve an IP address from the BOOTP server.
The following example illustrates the process:
console> enable
console# delete startup-config
Startup file was deleted
console# reload
You haven’t saved your changes. Are you sure you want to continue
(y/n) [n]?
This command will reset the whole system and disconnect your current
session. Do you want to continue (y/n) [n]?
******************************************************
/* the device reboots */
To verify the IP address, enter the show ip interface command.
The device is now configured with an IP address.
Security Management and Password Configuration
System security is handled through the Authentication, Authorization, and Accounting (AAA)
mechanism that manages user access rights, privileges, and management methods. AAA uses both local
and remote user databases. Data encryption is handled through the SSH mechanism.
The system is delivered with no default password configured; all passwords are user-defined. If a
user-defined password is lost, a password recovery procedure can be invoked from the Startup menu.
The procedure is applicable for the local terminal only and allows a one-time access to the device from
the local terminal with no password entered.
