exceeds the configured port MTU, the switch will not respond to the ping
message.
◆ 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.
Example
The following first enables jumbo frames for layer 2 packets, and then sets the MTU
for port 1:
Console(config)#jumbo frame
Console(config)#interface ethernet 1/1
Console(config-if)#switchport mtu 9216
Console(config-if)#
