Attaching Virtual Access Interface QoS Service Policies
Attaching a BBA Group to an Interface or Subinterface for PPPoE Sessions
You can attach a BBA group to physical interfaces and subinterfaces with varying encapsulations, or to
permanent virtual circuits (PVCs).
To attach a BBA group to an interface or subinterface, enter the following commands beginning in global
configuration mode:
Configuration Examples for Attaching a BBA Group to an Interface or Subinterface
Example 4-17 shows how to attach a BBA group named bba1 to the ATM interface 1/0/0 for PPPoE
sessions.
Example 4-17 Attaching a BBA Group to an Interface
Router(config)# interface atm 1/0/0
Router(config-if)# protocol pppoe group bba1
Router(config-if)# encapsulation ppp
Router(config-if)# pppoe enable
Example 4-18 shows how to attach a BBA group named bba-voice to ATM subinterface 4/0/0.10 for
PPPoE sessions. The example also assigns VLAN 4 to the subinterface.
Example 4-18 Attaching a BBA Group to a VLAN Subinterface
Router(config)# interface atm 4/0/0.10
Router(config-subif)# protocol pppoe group bba-voice
Router(config-subif)# encapsulation dot1q 4
Router(config-subif)# pppoe enable
Command Purpose
Step 1
Router(config)# interface type
slot/subslot/port.subinterface
Specifies the interface or subinterface to which you want to
attach the BBA group. Enters subinterface configuration
mode.
Step 2
Router(config-subif)# protocol pppoe group
group-name
Attaches the BBA group to the specified interface or
subinterface. Enables PPP over Ethernet (PPPoE) sessions to
be established on the interface, subinterface, or permanent
virtual circuits (PVCs).
Note The router applies the QoS policy of the virtual
template associated with the BBA group. The QoS
policy applies to this interface or subinterface and to
any PVCs configured on the interface or subinterface
without a specified policy.
