Configuring Ethernet Interfaces
Ethernet Interfaces
Setting the Administrative Distance. In any of the variations of the ip
address dhcp command, you can specify the administrative distance to use
when adding the DHCP gateway into the route table. The ProCurve Secure
Router uses the administrative distance to determine the best route when
multiple routes to the same destination exist. The router assumes that the
smaller the administrative distance, the more reliable the route is. The range
is 1 to 255; the default value is 1.
For example, to set an administrative distance of 5, enter:
ProCurve(config-eth 0/1)# ip address dhcp 5
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
