Configuring a Parameter Definition for Byte Adjustment

To associate a parameter instance with the byte adjustment application:

1. Configure traffic classes.

host1(config)#traffic-class voice

host1(config-traffic-class)#exit

host1(config)#traffic-class best-effort

host1(config-traffic-class)#exit

2. Create a parameter definition.

1. Configure the QoS parameter name and the application.

host1(config)#qos-parameter-define byteadjust1 application 
qos-byte-adjustment 

2. Configure a controlled-interface type.

host1(config-qos-parameter-define)#controlled-interface-type vlan

host1(config-qos-parameter-define)#controlled-interface-type ip

3. Configure an instance-interface type.

host1(config-qos-parameter-define)#instance-interface-type vlan

3. Do one of the following:

• Configure the shaping mode by issuing the qos-shaping-mode command.

The frame shaping mode is the default for Ethernet interfaces on all E-series routers. You can only set the cell shaping mode for Gigabit Ethernet and 10-Gigabit Ethernet interfaces configured on the ES2 4G LM on the E120 router and the E320 router.

• Configure the shaping mode by specifying the QoS cell mode application with a parameter definition.

host1(config)#qos-parameter-define cell-mode application qos-cell-mode

4. Attach the parameter definition to a logical Ethernet interface.

In this example, parameter instances are created for both the byte adjustment and QoS cell mode applications.

host1(config)#interface gigabitEthernet 7/0

host1(config-if)#encapsulation vlan

host1(config-if)#exit

host1(config)#interface gigabitEthernet 7/0.1

host1(config-if)#vlan id 1

host1(config-if)#qos-parameter byteadjustment -16

host1(config-if)#qos-parameter cell-mode 1

host1(config-if)#ip address 1.1.1.1 255.255.255.0
