Configuring Address Pool Usage Alarming; Binding Gateways To Dhcp Server's Mac Address - HPE FlexNetwork 10500 Series Configuration Manual

Step
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 DHCP server's MAC address

This feature enables the DHCP server to assign different gateway IP addresses to DHCP clients. In
addition, the DHCP server adds the gateway IP addresses and server's MAC address to the address
management module. The ARP module can then use the entries to reply ARP requests from the
clients.
As shown in
clients of different service types, such as broadband, IPTV, 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.
