For other traffic types, calculation of overall frame size is basically the
same, including the additional header fields SA(6) + DA(6) + Type(2) +
VLAN-Tag(4) (for tagged packets, for untaqged packets, the 4-byte
field will not be added by switch), and the payload. This should all be
less than the configured port MTU, including the CRC at the end of the
frame.
◆
For QinQ, the overall frame size is still calculated as described above,
and does not add the length of the second tag to the frame.
◆
The port MTU size can be displayed with the show show interfaces
status command.
