To change the MTU of a Layer 3 aggregate interface or subinterface:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter Layer 3 aggregate
interface or subinterface view.
interface route-aggregation
{ interface-number |

interfaces.
3. Enter aggregate interface
view.
• Enter Layer 2 aggregate interface
view:
