Setting Description Defaults
VoIP Aware Scan Alcatel-Lucent’s VoIP Call Admission Control (CAC)
prevents any single AP from becoming congested
with voice calls. When you enable CAC, you should
also enable VoIP Aware Scan in the ARM profile, so
the AP will not attempt to scan a different channel if
one of its clients has an active VoIP call. This option
requires that Scanning is also enabled.
Disabled
Power Save Aware
Scan
If enabled, the AP will not scan a different channel if
it has one or more clients that is in power save
mode.
Disabled
Video Aware Scan As long as there is at least one video frame every
100mSec the AP will reject an ARM scanning
request. Note that for each radio interface, video
frames must be defined in one of two ways:
n Classify the frame as video traffic via a session
ACL.
n Enable WMM on the WLAN’s SSID profile and
define a specific DSCP value as a video stream.
Next, create a session ACL to tag the video traffic
with the that DSCP value.
Enabled
Ideal Coverage Index The Alcatel-Lucent coverage index metric is a
weighted calculation based on the RF coverage for
all Alcatel-Lucent APs and neighboring APs on a
specified channel. The Ideal Coverage Index
specifies the ideal coverage that an AP should try to
achieve on its channel. The denser the AP
deployment, the lower this value should be.
Range: 2–20
For additional information on how this the Coverage
Index is calculated, see ARM Coverage and
Interference Metrics on page 454
In 6.4.4.0 and later
releases:
n default-a: 6
n default-g: 6
In earlier 6.4.x
releases:
n default:10
Acceptable Coverage
Index
For multi-band implementations, the Acceptable
Coverage Index specifies the minimal coverage an
AP it should achieve on its channel. The denser the
AP deployment, the lower this value should be.
Range: 1–6
4
Free Channel Index The Alcatel-Lucent Interference index metric
measures interference for a specified channel and
its surrounding channels. This value is calculated
and weighted for all APs on those channels
(including 3rd-party APs).
An AP will only move to a new channel if the new
channel has a lower interference index value than
the current channel. Free Channel Index specifies
the required difference between the two
interference index values before the AP moves to
the new channel. The lower this value, the more
likely it is that the AP will move to the new channel.
The range of possible values is 10–40.
For additional information on how this the Channel
Index is calculated, see ARM Coverage and
Interference Metrics on page 454.
In 6.4.4.0 and later
releases:
n default-a: 40
n default-g: 25
In earlier 6.4.x
releases:
n default: 25
