What is cdx6500dot5StatsTransmitDiscards?

This counter increments each time the port discards a frame because the transmit queue exceeded the limit set by cdx6500dot5TransmitQueueLimit. An admin watches this counter to detect sustained congestion that is causing actual packet loss on the port, rather than just transient queuing. For example, a steadily increasing count would tell the admin the port's traffic load is regularly overrunning its queue limit and frames are being lost.
