Notes: 1. The device configuration does not have to be deleted to retrieve an IP address for the DHCP server.
2. When copying configuration files, avoid using a configuration file that contains an instruction to enable DHCP on an
interface that connects to the same DHCP server, or to one with an identical configuration. In this instance, the
switch retrieves the new configuration file and boots from it. The device then enables DHCP as instructed in the
new configuration file, and the DHCP instructs it to reload the same file again.
Receiving an IP Address From a BOOTP Server
The standard BOOTP protocol is supported and enables the switch to automatically download its IP host configu-
ration 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 receive an IP address from the BOOTP
server.
The following example illustrates the process:
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 AAA (Authentication, Authorization, and Accounting) mechanism that
manages user access rights, privileges, and management methods. AAA uses both local and remote user data-
bases. 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 appli-
