Advanced Initial Device 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:
•
Assigning IP Addresses
•
Retrieving an IP Address from a DHCP Server
•
Retrieving an IP Address from a BOOTP Server
•
Security Management and Password Configuration
•
Software Download Through TFTP Server
•

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.
Assigning IP Addresses
Each switch must be assigned its own IP Address, which is used for communication with an SNMP network manager or
other TCP/IP application.
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. To retrieve an IP address from a
DHCP server:
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.
2. Enter the following commands to use the selected port for receiving the IP address. In the following example, the
commands are based on the port type used for configuration.
To assign dynamic IP addresses, enter the following command:
DGS3100# config ipif system dhcp
The interface receives the IP address automatically.
To verify the IP address, enter the show ip interface command at the system prompt as shown in the following example:
DGS3100# showIPIF
02-Jan-2000 00:24:01 %bootp_DHCP_CL-I-DHCPCONFIGURED: The device has been configured on interface Vlan 1 ,
IP 10.6.41.72, mask 255.255.255.244, DHCP server 10.6.41.226
The device configuration does not have to be deleted to retrieve an IP address for the DHCP server. When copying
configuration files, avoid using configuration files containing instructions to enable DHCP on an interface connected to the
same DHCP server, or to one with the identical configuration. 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.
