This read-only Counter64 counts the number of consecutive 8-byte errors the ARQ engine has corrected since the radio link last reached the linkOperational state. As one of the longest-burst counters in this family, its growth signals that the link is absorbing substantial, sustained corruption rather than brief noise. For example, a link that only recently started incrementing cwrArq8ByteErrs after months at zero would prompt an admin to check for a new source of interference or a developing hardware fault.
