for untagged packets.

Note:
To receive and process packets, the Ethernet MTU must include any extra
bytes that Layer-2 headers might require. To configure the IP MTU size,
which is the maximum size of the IP packet (IP IP payload), see
Section 14.2.9 “ip mtu” on page 14-11
.
Note:
You can use the
shutdown
command on physical and port-channel (LAG)
interfaces, but not on VLAN routing interfaces.
