Item Description
Forwarding Mode
• Remote Forwarding—The AC performs data forwarding.
Centralized forwarding comprises 802.3 centralized forwarding
and 802.11 centralized forwarding. With 802.3 centralized
forwarding, APs change incoming 802.11 frames to 802.3 frames
and tunnel the 802.3 frames to the AC. With 802.11 centralized
forwarding, APs directly tunnel incoming 802.11 frames to the AC.
• Local Forwarding—APs directly forward data frames. The AC still
performs authentication on clients. This forwarding mode reduces
the workload of the AC and retains the security and management
advantages of the AC/fit AP architecture.
• Forwarding Policy Based —Based on the forwarding policy that
matches the packets from clients, the AC chooses centralized
forwarding mode or local forwarding mode. This forwarding
mode reduces the workload of the AC. For more information, see
" Configuring policy-based forwarding ".
By default, the centralized forwarding mode is adopted.
IMPORTANT:
Forwarding policies are only available to packets sent by clients.
Local Forwarding VLAN
Clients using the same SSID might belong to different VLANs. You
can configure a local forwarding VLAN when configuring a local
forwarding policy.
Forwarding Policy
Enable the policy-based forwarding mode and apply the forwarding
policy to the access service.
Packet Format
• 802.11—Packets are encapsulated in 802.11 format in the data
tunnel and forwarded by the AC.
• 802.3—Packets are encapsulated in 802.3 format in the data
tunnel and forwarded by the AC.
This configuration only applies to a CAPWAP tunnel. For a LWAPP
tunnel, data frames can only be encapsulated in 802.11 format.
Beacon Measurement
• Enable—Enable the beacon measurement function.
• Disable—Disable the beacon measurement function.
By default, the beacon measurement function is disabled.
Beacon measurement, defined by 802.11k, provides a mechanism
for APs and clients to measure the available radio resources. When
this function is enabled, an AP periodically sends beacon requests to
clients. Clients respond with beacon reports to inform the AP of the
beacon measurement information they have collected.
