Managing and Troubleshooting the
DHCP Client
You should carefully monitor interfaces with dynamic addresses to ensure that
they have an address and are using the proper configurations.

Viewing the Interface's Lease

To view the active DHCP client leases on the router, enter:
ProCurve# show ip dhcp-client lease
The CLI displays all interfaces with dynamic addresses. For each interface, it
lists:
Temp IP address—the dynamic address
DHCP lease server
Lease—total time for the lease
Temp default gateway address
Client ID—typically, based on the MAC address
Primary DNS server
Figure 13-6 shows an example of a DHCP lease for an Ethernet 0/1 interface.
ProCurve# show ip dhcp-client lease
Interface: Ethernet 0/1
Temp IP address: 192.168.10.2, Mask: 255.255.255.0
DHCP Lease server: 192.168.10.1, State: Bound (3)
Lease: 86400 seconds
Temp default gateway address: 192.168.10.1
Temp Primary DNS: 10.1.1.1
Client-ID: 01:00:12:79:05:25:B0
Figure 13-6. Viewing Dynamic Configurations for Router Interfaces
If you see that the interface has received a configuration that it should not
have, such as a default route, you will have to restart the DHCP client. Follow
these steps:
1. Move to the configuration mode context for the DHCP client interface:
ProCurve(config)# interface frame-relay 1.101
Temp Secondary DNS: 0.0.0.0
Default route
