Run the following command to configure the MTU of the IP interface:
npu(config-if)# mtu <frame-size(68-1500)>
IMPORTANT
An error may occur if:
 The VLAN ID you have specified is not within the specified range, or is in use by another
interface. Refer the syntax description for the VLAN ID range.
 The VLAN ID is already used as a translated VLAN or a VLAN translation entry already exists
for this VLAN.
