Starting and Configuring the Device 53
Advanced Configuration
This section provides information about dynamic allocation of IP addresses and security
management based on the authentication, authorization, and accounting (AAA) mechanism, and
includes the following topics:
• Configuring IP Addresses through DHCP
• Configuring IP Addresses through BOOTP
• Security Management and Password Configuration
When configuring/receiving IP addresses through DHCP and BOOTP, the configuration received
from these servers includes the IP address, and may include subnet mask and default gateway.
Retrieving an IP Address From a DHCP Server
When using the DHCP protocol to retrieve an IP address, the device acts as a DHCP client. When
the device is reset, the DHCP command is saved in the configuration file, but not the IP address.
To retrieve an IP address from a DHCP server, perform the following steps:
1
Select and connect any port to a DHCP server or to a subnet that has a DHCP server on it, in
order to retrieve the IP address.
