Dynamic Configuration
Obtaining an IPv4 Address
If you select the “bootp” or “dhcp” option, the system will immediately start broadcasting service
requests. IP will be enabled but will not function until a BOOTP or DHCP reply has been received.
Requests are broadcast every few minutes using exponential backoff until IP configuration
information is obtained from a BOOTP or DHCP server. BOOTP and DHCP values can include the IP
address, subnet mask, and default gateway. If the DHCP/BOOTP server is slow to respond, you may
need to use the “ip dhcp restart client” command to re-start broadcasting service requests.
Note that the “ip dhcp restart client” command can also be used to start broadcasting service
requests for all VLANs configured to obtain address assignments through BOOTP or DHCP. It may
be necessary to use this command when DHCP is configured on a VLAN, and the member ports
which were previously shut down are now enabled.
If the “bootp” or “dhcp” option is saved to the startup-config file (step 6), then the switch will start
broadcasting service requests as soon as it is powered on.
To automatically configure the switch by communicating with BOOTP or DHCP address allocation
servers on the network, complete the following steps:
1. From the Global Configuration mode prompt, type “interface vlan 1” to access the
interface-configuration mode. Press <Enter>.
2. At the interface-configuration mode prompt, use one of the following commands:
• To obtain IP settings via DHCP, type “ip address dhcp” and press <Enter>.
• To obtain IP settings via BOOTP, type “ip address bootp” and press <Enter>.
3. Type “end” to return to the Privileged Exec mode. Press <Enter>.
