This read-only Counter reports the number of pause frames transmitted on this interface, capturing the same 802.3x pause-frame activity as els10-27FlowControlTxPauseFrames but recorded here as the standard counter type for this port's flow-control transmit history. An admin uses this figure to confirm whether this specific port has been asking connected devices to hold off sending, which points to congestion originating from traffic arriving on this port. For example, if this counter climbs on a port aggregating several downstream devices, the admin would investigate whether that port's uplink capacity needs to be increased to relieve the congestion.
