HP FlexNetwork MSR2003 User Manual

50
Upon receiving a DHCP request from the interface, the DHCP server performs address allocation in
the following ways:
• If a static binding is found for the client, the server assigns the static IP address and
configuration parameters from the address pool that contains the static binding.
• If no static binding is found for the client, the server uses the address pool applied to the
interface for address and configuration parameter allocation.
To apply an address pool on an interface:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter interface view.
interface
interface-type
interface-number
N/A
3. Apply an address pool on the
interface.
dhcp server apply ip-pool
pool-name
By default, no address pool is applied
on an interface.
If the applied address pool does not
exist, the DHCP server fails to perform
dynamic address allocation.
Configuring IP address conflict detection
Before assigning an IP address, the DHCP server pings that IP address.
• If the server receives a response within the specified period, it selects and pings another IP
address.
• If it receives no response, the server continues to ping the IP address until a specific number of
ping packets are sent. If still no response is received, the server assigns the IP address to the
requesting client. The DHCP client uses gratuitous ARP to perform IP address conflict
detection.
To configure IP address conflict detection:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. (Optional.) Set the maximum
number of ping packets to be
sent for conflict detection.
dhcp server ping packets
number
The default setting is one.
The value
0
disables IP address
conflict detection.
3. (Optional.) Set the ping
timeout time.
dhcp server ping timeout
milliseconds
The default setting is 500 ms.
The value
0
disables IP address
conflict detection.
Enabling handling of Option 82
Perform this task to enable the DHCP server to handle Option 82. Upon receiving a DHCP request
that contains Option 82, the DHCP server adds Option 82 into the DHCP response.
If you disable the DHCP to handle Option 82, it does not add Option 82 into the response message.
You must enable handling of Option 82 on both the DHCP server and the DHCP relay agent to
ensure correct processing for Option 82. For information about enabling handling of Option 82 on the
DHCP relay agent, see "Configuring Option 82."
