cd11IfRfStartChannelFrequency
Module: CISCO-DOT11-IF-MIB
OID (symbolic): CISCO-DOT11-IF-MIB::cd11IfRfStartChannelFrequency
OID (numeric): 1.3.6.1.4.1.9.9.272.1.1.2.15.1.6
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: This is the base channel frequency of the cd11IfRfStartChannelNumber channel from which subsequent channels of this frequency band are defined. The actual frequency value is defined and calculated by multiplying this object with the cd11IfRfFrequencyUnits. The subsequent channels in the band are calculated by adding the cd11IfRfChannelSpacingNumber multiplied by the cd11IfRfFrequencySpacing to this object value.
For example, the first channel of U-NII-1 band is channel 36, the cd11IfRfFrequencyUnits is 'mHz', the cd11IfRfStartChannelFrequency is '5180', and the cd11IfRfChannelSpacingNumber is 4. If the cd11IfRfFrequencySpacing is 5 MHz, the second supported channel of the U-NII-1 band will be channel 40 at frequency 5200 MHz.
What is cd11IfRfStartChannelFrequency?
Read-only value giving the base frequency of the first channel in this band, used as the reference point for calculating the actual frequency of all channels in the band.
