R2511-HP MSR Router Series Interface Configuration Guide(V5)

To configure a different MAC address for a specific Layer 3 Ethernet subinterface, you can use the
mac-address command.
HP recommends not configuring a MAC address in the VRRP-reserved MAC address range for a Layer 3
Ethernet subinterface.
To configure the MAC address of an Ethernet interface or subinterface:

Command Remarks
1. Enter system view.

2. Enter Ethernet interface view.

{ interface-number |
interface-number.subnumber }
N/A
3. Configure the MAC address
of the Ethernet interface or
subinterface.
mac-address mac-address
The default setting depends on the
router model.
You can display the MAC address of a
Layer 3 Ethernet interface by using the
display interface command.
The default MAC address of a Layer 3
Ethernet subinterface is the same as the
MAC address of its main interface.
Configuring the QoS token function
IMPORTANT:
The qmtoken command can cause an Ethernet interface to automatically shut down and go up.

The QoS token function is a flow control mechanism for the bottom layer queue for an Ethernet interface.
It uses tokens to set the maximum number of packets that the bottom layer queue can hold.
Custom queuing (CQ) or weight fair queuing (WFQ) takes effect when the bottom layer gets full. If the
bottom layer queue size is large, CQ or WFQ might fail to take effect when the interface is transmitting
data for TCP applications such as FTP, because TCP performs flow control. To resolve this problem, you
can configure the QoS token function to reduce the maximum number of tokens.
To ensure data transmission efficiency, use the default setting in normal cases.
