Mu Rate Limiting; Per Radio Mu Limit; Power Setting Configuration - Motorola AP-7131N-FGR Product Reference Manual

Introduction
IP filtering supports the creation of up to 20 filter rules enforced at layer 3. Once defined (using the
access point's SNMP, GUI or CLI), filtering rules can be enforced on the access point's LAN1, LAN2
and WLAN interfaces. An additional default action is also available denying traffic when the filter
rules fail. Lastly, imported and exported configurations retain their defined IP filtering configurations.
For information on configuring the access point's IP filtering functionality, see Configuring IP Filtering
on page 5-76.

1.1.2 MU Rate Limiting

MU rate limiting enables an administrator to determine how much radio bandwidth is allocated to
each MU within any one of the 16 supported WLANs.
Before this 4.0 baseline release, Motorola access points supported bandwidth management on a per-
WLAN basis. Each WLAN could be configured to receive (at most) a certain percentage of the total
available downstream bandwidth. The new rate limiting feature is a replacement of the bandwidth
management feature allowing for better MU radio bandwidth allotments on a per WLAN basis.
To globally enable or disable the MU rate limit and assess the WLANs in which it's currently invoked,
see Configuring MU Rate Limiting on page 5-70.
To define the actual MU rate limit (maximum downstream bandwidth allocation in kbps), see
Creating/Editing Individual WLANs on page 5-32.

1.1.3 Per Radio MU Limit

Prior to this new 4.0 AP firmware baseline, an access point allowed a total of 127 MU associations,
regardless of the number of radios on the AP. With a dual-radio AP, if there were already 127 MUs
associated to one radio, that were no slots available for a MU to associate with another radio.
With the new 4.0 firmware, an AP can reserve slots on each radio so MUs of one radio type (11a/n
or 11bg/n) have better chances for AP association. Therefore, the total number of MUs allowed to
associate remains at 127, but you can now strategically distribute the 127 MU associations between
the data radios.
For information on setting the number of MU associations on a specific radio, see Configuring the
802.11a/n or 802.11b/g/n Radio on page 5-59.

1.1.4 Power Setting Configuration

The access point's power management functionality automatically configures the AP's operational
mode so it safely operates within available power. The power setting feature enables the user to
