6.1(2)I1(0.349)

Description (partial)

Symptom:
Packets between 9212-9216 bytes switched over the ingress of Subinterfaces  are not counted as Jumbo packets when viewing "show interface" counters. Output packets and bytes are incrementing, however the Jumbo packet count is not incremented.

Conditions:
Occurs for packet sizes of 9212 or above.  This is due to the VLAN encapsulation of 4 bytes added for Packets going over a sub-interface, and currently only packets up to 9216 are counted as jumbo.
