Configuring Ethernet Interfaces
Ethernet Interfaces
3-8
Overriding Settings Received from the DHCP Server. If the DHCP
server is configured to provide a default-route, a domain name, or a domain
name server (DNS), the DHCP client for the Ethernet interface will accept and
use these settings. If you do not want to use any of these settings, enter:
Syntax: ip address dhcp [hostname <hostname> | no-default-route | no-domain-
name | no-nameservers]
For example, if you do not want the DHCP client to use the route settings and
name (DNS) server settings that it receives from the DHCP server, enter:
ProCurve(config-eth 0/1)# ip address dhcp no-default-route no-nameservers
If you do not want the DHCP client to use any of the default settings, enter:
ProCurve(config-eth 0/1)# ip address dhcp no-default-route no-domain-name no-
nameservers
Releasing or Renewing an IP address. If you want to manually force the
Ethernet interface to release or renew an IP address, enter these commands
from the Ethernet interface configuration mode context:
ProCurve(config-eth 0/1)# ip dhcp release
ProCurve(config-eth 0/1)# ip dhcp renew
Remove the DHCP Client Setting. If you decide that you no longer want
the Ethernet interface to be a DHCP client, enter:
ProCurve(config-eth 0/1)# no ip address dhcp
Changing a Setting for the DHCP Client. If you want to change a setting
for the DHCP client, you must first disable the client. Then you can enter the
command to enable the client with the setting that you want to change.
Before you disable the client, you should release the IP address obtained
through DHCP. This will prevent the DHCP server from holding the IP address
and allow it to assign the IP address to another client.
For example, if you enabled the DHCP client with all the default settings and
later determined that you wanted the router to function as the DNS server for
the Ethernet interface, you would enter:
ProCurve(config-eth 0/1)# ip dhcp release
ProCurve(config-eth 0/1)# no ip address dhcp
ProCurve(config-eth 0/1)# ip address dhcp no-nameservers
