Command History
Usage Guidelines The MTU_Mismatch column in the command output indicates whether all the ports in the VLAN have
the same MTU. When “yes” is displayed in the MTU_Mismatch column, it means that the VLAN has a
port with different MTUs, and packets might be dropped that are switched from a port with a larger MTU
to a port with a smaller MTU. If the VLAN does not have an SVI, the hyphen (-) symbol is displayed in
the SVI_MTU column.
For a VLAN, if the MTU-Mismatch column displays yes, the names of the port with the MinMTU and
the port with the MaxMTU are displayed. For a VLAN, if the SVI_MTU is bigger than the MinMTU,
“TooBig” is displayed after the SVI_MTU.
Examples This is an example of output from the show vlan mtu command:
Switch> show vlan mtu
