ping packets to be sent for
conflict detection.

Enabling handling of Option 82

With Option 82 handling enabled, when the DHCP server receives a request with Option 82, it adds
Option 82 into the response.
If the server is configured to ignore Option 82, it assigns an IP address to the client without adding
Option 82 in the response message.

Configuration prerequisites

Before you perform this configuration, complete the following configurations on the DHCP server:
1. Enable DHCP.
2. Configure the DHCP address pool.

Enabling Option 82 handling

To enable the DHCP server to handle Option 82:
Step

2. Enable the server to handle
Option 82.
To support Option 82 requires configuring both the DHCP server and relay agent (or the device enabled
with DHCP snooping). For more information, see
DHCP snooping."
