Option 82 Configuration
The APC uses the DHCP Option 82 to provide various services during IP allocation by
forwarding the information such as access control, QoS, or security policy etc., when a
wireless terminal connected to an AP receives an IP address.
The Option 82 has two fields that are remote ID and circuit ID. Enter the name of an
interface for which the APC constantly does relay/proxy in the circuit ID and enter a part
of AP information in the remote ID accordingly. One of the following three data can be
used as the remote id of Option 82:
• ap-mac: 802.11 MAC data of the AP. The length is 12-byte (Default).
• ap-mac-ssid: The character string of SSID is added to the data of AP-
MAC. The length is variable.
• ap-mac-ssid: Ethernet MAC data of the AP. The length is 12-byte.
To configure Option 82 related functions, go to the interface mode by executing the
following command:
WEC8500# configure terminal
