This read-only counter tallies packets dropped by the pipe specifically at a given precedence level, breaking down the pipe-wide clvPipeDropedPackets figure by priority class. It lets an admin see exactly which traffic priority is bearing the brunt of any buffer-exhaustion drops. For example, if clvPipePrecDropedPackets shows drops concentrated in a low-priority precedence while higher precedences show none, the shaping configuration is working as intended by sacrificing bulk traffic first.
