Option 82

to a DHCP server. The DHCP server can use this information to implement IP
addressing or other parameter-assignment policies.

allowing you to determine what information is provided in the Option 82 Circuit ID

IP and MAC Binding
When the device is configured as a DHCP server or for DHCP relay, you can bind
static IP addresses to up to 100 network devices, such as a web server or an FTP
server. Binding does not assign an IP address to a device. You should ensure that
each device bound to a static IP address in the IP & MAC binding table is
configured to use a static IP address.
Typically the MAC address of a device physically appears on a label on the
bottom panel or back panel of a device.
