Cisco Cisco MGX-FRSM-HS2 B Serial Frame Service Module Manual Técnica

This document details the functionality and operation of Radio Resource Management (RRM) and provides an
in−depth discussion of the algorithms behind this feature.

Cisco recommends that you have knowledge of these topics:

Lightweight Access Point Protocol (LWAPP)

• 

Common wireless LAN (WLAN)/radio frequency (RF) design considerations (knowledge comparable
to that of the Planet 3 Wireless CWNA certification)

• 

Note: Client Aggressive Load−Balancing and Rogue Detection/Containment (and other Cisco Intrusion
Detection System [IDS]/Cisco IOS® Intrusion Prevention System [IPS] features) are not functions of RRM
and are beyond the scope of this document.

This document is not restricted to specific software and hardware versions.

Refer to Cisco Technical Tips Conventions for more information on document conventions.

From the CLI, check:

show advanced [802.11b|802.11a] txpower

The new default value is −70dbm. If it has been modified, revert to the defaults since this new value
has been shown to be optimal under a range of conditions. This value needs to be the same on all the
controllers in an RF group. Remember to save the configuration after making changes.

In order to change this value, issue this command:

config advanced [802.11b|802.11a] tx−power−control−thresh 70

1. 

From the CLI, check:

show advanced [802.11a|802.11b] profile global

The results should be:

802.11b Global coverage threshold.............. 12 dB for 802.11b

802.11a Global coverage threshold.............. 16 dB for 802.11a

If the results are different, then you use these commands:

config advanced 802.11b profile coverage global 12

config advanced 802.11a profile coverage global 16
