Managing And Troubleshooting The Dhcp Server; Viewing Dhcp Client Bindings - HP ProCurve 7000dl Series Basic Management And Configuration Manual

Managing and Troubleshooting the
DHCP Server
As you troubleshoot DHCP functions, you will enter show and debug com-
mands. You can enter these commands either from the enable mode context
or from configuration mode contexts. If you enter one of these commands
from a configuration mode context, you must add do to the command. For
example:
ProCurve(config-dhcp)# do show ip dhcp-server binding

Viewing DHCP Client Bindings

The ProCurve Secure Router stores a table of DHCP bindings. In this table,
you can view the IP addresses for all active DHCP clients served by the router.
This can be helpful for troubleshooting. For example, you can ping a work-
station to see if it can respond. Or you can zero-in on a host that is flooding a
network with messages.
To view the bindings for all DHCP clients supported by the router, enter:
ProCurve# show ip dhcp-server binding
The table displays:
IP Address—the committed IP address
Client ID—usually a MAC address
Lease Expiration—date and time the lease for the address expires
Client Name—the user-selected name on the computer or device
Figure 13-5 shows an example of the information that displays when you enter
the show ip dhcp-server binding command.
