If non-zero, packets are being dropped because they exceed the max size limit.

Whenever a packet is received with a size larger than the maximum large capture packet size limit, this metric is incremented by one.

Note: If you are using one or more 10-gigabit fiber network interface cards and are experiencing capture traffic quality issues, it can be caused by the fiber interface card and driver issues. If the DNCA is not using Intel chipset-based NIC interface cards, Discover highly recommends that you switch to NICs by using Intel chipsets.

Under the Interface tab in the Tuning Parameters view, the Max large capture packet size field defines the maximum large capture packet size limit.

  • By default, this setting is set to 40 KB.
  • As needed, this setting can be increased to accommodate systems that have features such as large receive offload (LRO) enabled.

Increasing the Max large capture packet size must stop metric on the Summary tab from increasing.
