NOTE
For information on setting the configuration of a three radio model Altitude 4750, see “Configuring the
802.11a/n or 802.11b/g/n Radio” on page 174 .
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 188 .
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.
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 184 .
To define the actual MU rate limit (maximum downstream bandwidth allocation in kbps), see
“Creating/Editing Individual WLANs” on page 148 .
Per Radio MU Limit
An Access Point 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 174 .
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 select
one of three power operating modes, 3af, 3at and full power. When an Access Point is operating in
either 3af or 3at mode, the transmit power is always lower than the full power setting. With the
introduction of the Altitude 4750 model Access Point and its optional three radio SKU, the power
options available amongst single, dual and three radio model Access Points has never been more
diverse, and careful consideration must be made before deploying the Access Point.
