cwrArqDataLatency
Module: CISCO-WIRELESS-IF-MIB
OID (symbolic): CISCO-WIRELESS-IF-MIB::cwrArqDataLatency
OID (numeric): 1.3.6.1.4.1.9.9.136.1.4.1.1.3
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: This object specifies the expected latency values for data. Reducing the latency, provides the ARQ engine less time to correct codeword errors. So if latency is reduced sufficiently, the data throughput will get effected. Also note that the latency values on both ends of the link should be kept identical, else the data throughput will be effected.
What is cwrArqDataLatency?
This read-write Integer32, in milliseconds, specifies the expected latency for data traffic through the ARQ subsystem; reducing it leaves the ARQ engine less time to correct codeword errors, which can reduce throughput, and both link ends should be set to matching values. An admin tunes this to balance latency-sensitive applications against error-correction effectiveness. For example, mismatching cwrArqDataLatency between the two ends of a link is a common configuration mistake an admin should check for when troubleshooting unexpectedly low throughput.
