Parameter Description Range Default
band-steering
ARM’s band steering feature can encourage or
require dual-band capable clients to stay on the
5GHz band on dual-band APs. This frees up
resources on the 2.4GHz band for single band
clients like VoIP phones.
Band steering reduces co-channel interference
and increases available bandwidth for dual-
band clients, because there are more channels
on the 5GHz band than on the 2.4GHz band.
Dual-band 802.11n-capable clients may see
even greater bandwidth improvements,
because the band steering feature will
automatically select between 40MHz or 20MHz
channels in 802.11n networks. This feature is
disabled by default, and must be enabled in a
Virtual AP profile.
The band steering feature supports three
steering modes, which can be configured via
the steering-mode parameter:
Band steering can be configured on both
campus APs and remote APs that have a virtual
AP profile set to tunnel, decrypt-tunnel, split-
tunnel or bridge forwarding mode. Note,
however, that if a campus or remote APs has
virtual AP profiles configured in bridge or split-
tunnel forwarding mode but no virtual AP in
tunnel mode, those APs will gather information
about 5G-capable clients independently and
will not exchange this information with other
APs that also have bridge or split-tunnel virtual
APs only.
— disabled
blacklist
Enables detection of denial of service (DoS)
attacks, such as ping or SYN floods, that are not
spoofed deauth attacks.
— enabled
blacklist-time
Number of seconds that a client is quarantined
from the network after being blacklisted.
0-2,147,483,647
seconds
3600
seconds
(1 hour)
broadcast-filter
Filter out broadcast and multicast traffic in the
air.
— disabled
all
Filter out broadcast and multicast traffic in the
air.
NOTE: Do not enable this option for virtual APs
configured in bridge forwarding mode. This
configuration parameter is only intended for use
for virtual APs in tunnel mode. In tunnel mode,
all packets travel to the controller, so the
controller is able to drop all broadcast traffic.
When a virtual AP is configured to use bridge
forwarding mode, most data traffic stays local
to the AP, and the controller is not able to filter
out that broadcast traffic.
IMPORTANT: If you enable this option, you must
also enable the Broadcast-Filter ARP parameter
in the stateful firewall configuration to prevent
ARP requests from being dropped. Note also
— enabled
