Usage Guidelines
In the show vlan mtu command output, the MTU_Mismatch column shows whether all the ports in the
VLAN have the same MTU. When yes appears in this column, it means that the VLAN has ports with
different MTUs, and packets that are switched from a port with a larger MTU to a port with a smaller
MTU might be dropped. If the VLAN does not have an SVI, the hyphen (-) symbol appears in the
SVI_MTU column. If the MTU-Mismatch column displays yes, the names of the port with the MinMTU
and the port with the MaxMTU appear.
