Parameter Description Range Default
controller with a PEFNG license.
dynamic-mcast-optimization-
threshold
Maximum number of high-throughput stations in
a multicast group beyond which dynamic
multicast optimization stops. 2-255 stations 6 stations
fdb-update-on-assoc
This parameter enables seamless failover for
silent clients, allowing them to re-associate. If
you select this option, the controller will gen-
erate a Layer 2 update on behalf of client to
update forwarding tables in bridge devices.
Default: Disabled
— disabled
forward-mode
Controls whether 802.11 frames are tunneled to
the controller using generic routing
encapsulation (GRE), bridged into the local
Ethernet LAN (for remote APs), or a combination
thereof depending on the destination (corporate
traffic goes to the controller, and Internet
access remains local).
Select one of the following forward modes:
l
Tunnel: When an AP is in tunnel forwarding
mode, the AP handles all 802.11 association
requests and responses. The AP sends all
802.11 data packets, action frames and
EAPOL frames over a GRE tunnel to the
controller for processing. The controller
removes or adds the GRE headers, decrypts
or encrypts 802.11 frames and applies
firewall rules to the user traffic as usual.
l
Bridge: When an AP is in bridge mode, data
is bridged onto the local Ethernet LAN.
When in bridge mode, the AP handles all
802.11 association requests and responses,
encryption/decryption processes, and
firewall enforcement. 802.11e and 802.11k
action frames are also processed by the AP,
which then sends out responses as needed.
An AP in bridge mode supports only the
802.1x authentication type.
l
Split-Tunnel: Data frames are either
tunneled or bridged, depending on the
destination (corporate traffic goes to the
controller, and Internet access remains
local). The AP handles all 802.11 association
requests and responses,
encryption/decryption, and firewall
enforcement. 802.11e and 802.11k action
frames are also processed by the AP, which
then sends out responses as needed. An AP
in split-tunnel mode supports only the 802.1x
authentication type.
l
Decrypt-Tunnel: An AP in decrypt-tunnel
forwarding mode decrypts and
decapsulates all 802.11 frames from a
station and sends the 802.3 frames through
the GRE tunnel to the controller, which then
applies firewall policies to the user traffic.
