CAUTION:
•
To view the traffic statistics on Ethernet subinterfaces, use the display interface command.
• Do not simultaneously enable traffic statistics collection and ACL functions (such as packet filtering and
Portal) that may conflict with the traffic statistics collection.
• This feature is available only on SPE cards.
Configuring a VE interface
Introduction
Virtual Ethernet (VE) interfaces are logical interfaces implemented on interface cards. They fall into Layer
3 VE interfaces and Layer 2 VE-bridge interfaces. The VE interfaces are mainly used for IPoEoA and EoA.
IPoEoA and EoA carry Ethernet packets over ATM by binding VE interfaces to permanent virtual channels
(PVCs). IPoEoA is for Layer 3 VE interface binding, and EoA is for Layer 2 VE interface binding. For more
information, see Layer 2—WAN Configuration Guide.
Configuration procedure
When implementing IPoEoA and EoA through a PVC, you must associate the PVC with a VE interface.
Otherwise, you cannot configure the PVC.
Configuring a Layer 3 VE interface
To configure a Layer 3 VE Interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Create a Layer 3 VE interface
and enter Layer 3 VE interface
view.
interface virtual-ethernet
interface-number
If the specified Layer 3 VE interface
already exists, you enter Layer 3
VE interface view directly.
You can create up to 1024 Layer 3
VE interfaces.
3. Change the MAC address of
the Layer 3 VE interface.
mac-address mac-address
Optional.
After configuring this command,
run the reset arp command to make
the new MAC address take effect.
For more information about the
reset arp command, see Layer
3—IP Services Command
Reference.
Configuring a Layer 2 VE interface
To configure a Layer 2 VE Interface:
Step Command Remarks
1. Enter system view. system-view N/A
