Description (partial)

Symptom:
Timeout discards(drops) are not being counted as output discards on the fc interface. The "discards" counter will not include any frames discarded due to them reaching the congestion-drop threshold.

fc2/1 is up
    Hardware is Fibre Channel, SFP is short wave laser w/o OFC (SN)
    Port WWN is 20:41:54:7f:ee:d9:4c:80
    Admin port mode is F, trunk mode is off
...
      800 frames output, 1703820 bytes
