Dynamic Configuration
Obtaining an IPv4 Address
If you select the “dhcp” option, the system will immediately start broadcasting
service requests. IP will be enabled but will not function until a DHCP reply has
been received. Requests are broadcast every few minutes using exponential
backoff until IP configuration information is obtained from a DHCP server. DHCP
values can include the IP address, subnet mask, and default gateway. If the DHCP
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 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 “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 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 the following command:

To obtain IP settings via DHCP, type “ip address dhcp” and press <Enter>.
