ONFIGURATION
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>.
4.
Wait a few minutes, and then check the IP configuration settings by
typing the “show ip interface” command. Press <Enter>.
