IP Filtering

IP filtering determines which IP packets are processed normally and which are discarded. If

discarded, the packet is deleted and completely ignored (as if never received). Optionally apply

different criteria to better refine which packets to filter.

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 5-181.

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 the 4.x firmware baseline, Mobility 7131 series 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 5-176.

To define the actual MU rate limit (maximum downstream bandwidth allocation in kbps), see

Creating/Editing Individual WLANs on page 5-139.

Per Radio MU Limit

Prior to the 4.x AP firmware baseline, an Mobility 7131 Access Point series 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.

An access point can now reserve slots on each radio so MUs of one radio type (11a/n or 11/jointfilesconvert/389239/bg/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 5-167.
