cwrLocalLoopbackPoint
Module: CISCO-WIRELESS-IF-MIB
OID (symbolic): CISCO-WIRELESS-IF-MIB::cwrLocalLoopbackPoint
OID (numeric): 1.3.6.1.4.1.9.9.136.1.1.1.1.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object represents the point in the system where the data signal is looped back.
none(0) - no loopback codec(1) - loopback at the Encoder/Decoder module. This exercises the framer, and codec modules framer(2) - loopback at the 'framer' module. fir(3) - loopback at the 'Finite Impulse Response' module. This exercises the framer, codec, and FIR modules. if(4) - loopback at the 'Internal Frequency' module using both the main and the diversity receive paths. This exercises the framer, codec, FIR, and IF modules. rf(5) - loopback at the main RF unit via the main receive path in the IF module. This exercises the framer, codec, FIR, IF, and RF modules. rfDiversity(6) - loopback at the main RF unit but route it through the diversity receive path in the IF module. This exercises the framer, codec, FIR, IF, and RF modules. ifMain(7) - loopack at the IF module using only the Main receive path. This exercises the framer, codec, FIR, and IF modules. ifDiversity(8) - loopack at the IF module using only the diversity receive path. This exercises the framer, codec, FIR, and IF modules.
What is cwrLocalLoopbackPoint?
A read-write INTEGER enumeration selecting the point in the signal path, such as codec, framer, or FIR, at which the data signal is looped back for testing, or none for normal operation. Each loopback point exercises a different subset of hardware modules, so choosing the right one isolates whether a fault lies in the encoder/decoder, framer, or RF stages. For example, setting cwrLocalLoopbackPoint to codec loops the signal back at the encoder/decoder stage, letting a technician verify that module and the framer without needing the RF path to be error-free.
