Configuring Address Pool Usage Alarming; Binding Gateways To A Common Mac Address - HP FlexNetwork MSR2003 Configuration Manual

Step
2. Configure the DHCP server to
back up the bindings to a file.
3. (Optional.) Manually save the
DHCP bindings to the backup
file.
4. (Optional.) Set the waiting
time after a DHCP binding
change for the DHCP server
to update the backup file.
5. (Optional.) Terminate the
download of DHCP bindings
from the backup file.

Configuring address pool usage alarming

Perform this task to set the threshold for address pool usage alarming. When the threshold is
exceeded, the system sends log messages to the information center. According to the log
information, you can optimize the address pool configuration. For more information about the
information center, see Network Management and Monitoring Configuration Guide.
To configure address pool usage alarming:
Step
1. Enter system view.
2. Create a DHCP address pool
and enter its view.
3. Set the threshold for address
pool usage alarming.

Binding gateways to a common MAC address

This feature enables DHCP clients of different types to obtain different gateway IP addresses but the
same MAC address. In addition to assigning gateway IP addresses to the clients, the DHCP server
adds the gateway IP addresses and server's MAC address to the address management module. The
ARP module can use the entries to reply ARP requests from the clients.
As shown in
clients of different service types, such as broadband, IP TV, and IP telephone. The clients of different
types obtain IP addresses on different subnets. For the clients to access the network, the access
interface typically has no IP address configured. You must bind the gateways to a MAC address
when specifying gateways for the DHCP clients.

Remarks
By default, the DHCP server
does not back up the DHCP
bindings.
With this command executed,
the DHCP server backs up its
bindings immediately and runs
auto backup.
