This field reports the total number of packets (including bad packets) transmitted that were between 2048 and 4095 octets in length inclusive (excluding framing bits but including FCS octets), exposed here as cienaCesPmExtendedTxRxTotalStatsBinTx2048To4095OctsPkts. On this Ciena CES port's PM data, this bucket counts frames in the 2048-4095 octet range, well above standard Ethernet size, so it only moves when genuinely large jumbo frames — typical of storage replication or bulk backup traffic — are crossing this specific port; and this is the running grand-total counter for the extended Tx/Rx PM group, tallied since the bin's own StartTime (in practice since the PM instance was created or last reset), so treat it as a lifetime tally rather than a per-interval number. For example, a moderately busy port showing 315,000 2048-4095-byte frames for this bin would be a plausible, unremarkable reading.
