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.
