Item Description
Forwarding Mode
• Remote Forwarding—The AC performs data forwarding. Centralized
forwarding includes 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 (see " Configuring policy-based forwarding ").
By default, the centralized forwarding mode is adopted.
IMPORTANT:
Forwarding policies can only take effect on 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 and forwarded by the
AC.
• 802.3—Packets are encapsulated in 802.3 format and forwarded by the
AC.
This configuration only applies to a CAPWAP tunnel. For an 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.
