Setting the MTU for an Ethernet interface or subinterface
The value of maximum transmission unit (MTU) affects the fragmentation and re-assembly of IP packets.
To set the MTU for an Ethernet interface or subinterface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Ethernet interface or
subinterface view.
interface interface-type
{ interface-number |
interface-number.subnumber }
N/A
3. Set the MTU. mtu size The default setting is 1500 bytes.
Enabling traffic statistics collection on an Ethernet subinterface
This feature enables you to monitor traffic by providing the statistics about the inbound and outbound
unicast packets, multicasts, and broadcasts of a subinterface.
To enable traffic statistics collection on an Ethernet subinterface:
Step Command Remarks
1. Enter system view. system-view N/A
