Table 5-19 Operation Rate Set for 802.11a Cisco Radios
Parameter Range (Note)
6000 Kilo Bits Mandatory, Supported or Disabled.
9000 Kilo Bits Mandatory, Supported or Disabled.
12000 Kilo Bits Mandatory, Supported or Disabled.
18000 Kilo Bits Mandatory, Supported or Disabled.
24000 Kilo Bits Mandatory, Supported or Disabled.
36000 Kilo Bits Mandatory, Supported or Disabled.
48000 Kilo Bits Mandatory, Supported or Disabled.
54000 Kilo Bits Mandatory, Supported or Disabled.
Note The data rates set here are negotiated between the client and the controller. If the data rate is set
to Mandatory, the client must support it in order to use the network.
If a data rate is set as supported by the controller, any associated client that also supports that
same rate may communicate with the access point using that rate. But it is not required that a
client be able to use all the rates marked Supported in order to associate. Each data rate can also
be set to Disabled to match client settings.
Table 5-20 MAC Operation Parameters
Parameter Description
Configuration Type Automatic or Custom.
RTS Threshold This attribute shall indicate the number of octets in an MPDU, below which
an RTS/CTS handshake shall not be performed. An RTS/CTS handshake
shall be performed at the beginning of any frame exchange sequence where
the MPDU is of type Data or Management, the MPDU has an individual
address in the Address1 field, and the length of the MPDU is greater than
this threshold. Setting this attribute to be larger than the maximum MSDU
size shall have the effect of turning off the RTS/CTS handshake for Data or
Management type frames transmitted by this STA. Setting this attribute to
zero shall have the effect of turning on the RTS/CTS handshake for all
frames of Data or Management type transmitted by this STA. The default
value of this attribute shall be 2347.
Short Retry Limit The maximum number of transmission attempts of a frame, the length of
which is less than or equal to dot11RTSThreshold, that shall be made
before a failure condition is indicated. The default value of this attribute
shall be 7.
Long Retry Limit The maximum number of transmission attempts of a frame, the length of
which is greater than dot11RTSThreshold, that shall be made before a
failure condition is indicated. The default value of this attribute shall be 4.
