Specifying Gateways For Dhcp Clients - HPE FlexNetwork 10500 Series Configuration Manual

Step
9. (Optional.) Exclude the specified
IP addresses from dynamic
allocation globally.
Configuring a static binding in a DHCP address pool
Some DHCP clients, such as a WWW server, need fixed IP addresses. To provide a fixed IP address
for a client, you can statically bind the MAC address or ID of the client to an IP address in a DHCP
address pool. When the client requests an IP address, the DHCP server assigns the IP address in
the static binding to the client.
Follow these guidelines when you configure a static binding:
•
One IP address can be bound to only one client MAC or client ID. You cannot modify bindings
that have been created. To change the binding for a DHCP client, you must delete the existing
binding first.
•
The IP address of a static binding cannot be the address of the DHCP server interface.
Otherwise, an IP address conflict occurs and the bound client cannot obtain an IP address
correctly.
•
Multiple interfaces on the same device might all use DHCP to request a static IP address. In this
case, use client IDs rather than the device's MAC address to identify the interfaces. Otherwise,
IP address allocation will fail.
To configure a static binding:
Step
1. Enter system view.
2. Create a DHCP address pool
and enter its view.
3. Configure a static binding.
4. (Optional.) Set the lease
duration for the IP address.

Specifying gateways for DHCP clients

DHCP clients send packets destined for other networks to a gateway. The DHCP server can assign
the gateway address to the DHCP clients.
You can specify gateway addresses in each address pool on the DHCP server. A maximum of 64
gateways can be specified in DHCP address pool view or secondary subnet view.
The DHCP server assigns gateway addresses to clients on a secondary subnet in the following
ways:
Command
dhcp server forbidden-ip
start-ip-address [ end-ip-address ]
Command
system-view
dhcp server ip-pool pool-name
static-bind ip-address ip-address
[ mask-length | mask mask ]
{ client-identifier client-identifier |
hardware-address
hardware-address [ ethernet |
token-ring ] }
expired { day day [ hour hour
[ minute minute [ second
second ] ] ] | unlimited }

Remarks
Except for the IP address of
the DHCP server interface,
IP addresses in all address
pools are assignable by
default.
To exclude multiple address
ranges globally, repeat this
step.
Remarks
N/A
By default, no DHCP address
pool exists.
By default, no static binding is
configured.
To add more static bindings,
repeat this step.
The default setting is 1 day.
