HP VPN Firewall Appliances Network Management Configuration Guide

{ When the device serves as a DHCP client or BOOTP client, you must bind the DHCP client's ID
to an IP address, or bind the BOOTP client's MAC address to an IP address on the DHCP server.
Otherwise, the DHCP or BOOTP client cannot obtain a static IP address.
{ If the interfaces on a DHCP client share the same MAC address, specify the client ID, rather than
MAC address, in a static binding to identify the requesting interface. If you do not do this, the
client might fail to obtain an IP address.
To configure a static binding in a common address pool:

Command Remarks
1. Enter system view.
system-view N/A
2. Enter common address pool view.
dhcp server ip-pool pool-name N/A
3. Specify the IP address.
static-bind ip-address ip-address
[ mask-length | mask mask ]
No IP addresses are
statically bound by
default.
4. Specify the MAC address or client
ID.
• Specify the MAC address:
static-bind mac-address
mac-address
• Specify the client ID:
static-bind client-identifier
client-identifier
Use either of the
commands.
Neither is bound statically
by default.
5. Specify the lease duration for the IP
address.
expired { day day [ hour hour
[ minute minute [ second second ] ] ] |
unlimited }
Optional.
By default, the lease
duration of the IP address
is unlimited.
• Configuring dynamic address allocation.
For dynamic address allocation, you must configure a DHCP address pool, specify one and only
one address range for the pool, and specify the lease duration. A DHCP address pool can have
only one lease duration.
To avoid address conflicts, configure the DHCP server to exclude IP addresses used by the
gateway or FTP server from dynamic allocation.
Follow these guidelines when you configure dynamic address allocation:
{ In common address pool view, using the network or network ip range command repeatedly
overwrites the previous configuration.
{ After you exclude IP addresses from automatic allocation by using the dhcp server forbidden-ip
command, neither a common address pool nor an extended address pool can assign these IP
addresses through dynamic address allocation.
{ Using the dhcp server forbidden-ip command repeatedly can exclude multiple IP address
ranges from allocation.
