DHCP Relay Settings

This chapter describes how to configure your unit’s DHCP Relay agent settings. 
You can configure up to five profiles for the DHCP Relay agent on your 
BelAir20E. Each profile specifies a subnet interface, which can be either the 
node’s system interface or a VLAN. The DHCP server assigns an IP address to 
the client according to the subnet of this interface.

Each profile also contains the IP addresses for up to three DHCP servers. 
When a profile is activated, the DHCP agent forwards a DHCP request to all 
the listed servers. The DHCP client receives packets from the first server to 
respond to the request.

Profiles offer an easy way of configuring different DHCP servers for each subnet 
interface.

Your BelAir20E can also add BelAir Networks specific information to the 
DHCP packets sent to the wireless client.

Finally, you can create a list of valid IP address subnets to filter out unwanted 
directed and broadcast DHCP packets from your wireless network.

The following topics are covered in this chapter:

•

“Displaying the DHCP Relay Configuration” on page 145

•

“Modifying DHCP Relay Parameters” on page 146

•

“Interface Administrative State” on page 147

•

“Assigning SSID Traffic to Use DHCP Relay” on page 147

•

“DHCP Address Filtering” on page 147
