Example: Configuring a PPPoE Subinterface over a VLAN for a LAG Bundle

206
host1(config-if)#lacp passive
host1(config-if)#interface fastEthernet 4/3
host1(config-if)#speed 100
host1(config-if)#duplex full
host1(config-if)#lacp passive
The following commands add the Ethernet physical interfaces to a LAG bundle named
chicago.
host1(config)#interface lag chicago
host1(config-if)#member-interface fastEthernet 4/0
host1(config-if)#member-interface fastEthernet 4/3
The following commands configure a PPPoE subinterface for the LAG bundle named
chicago. In the LAG interface identification command (interface lag chicago.1), the
number 1 represents the subinterface number for the PPPoE subinterface.
host1(config-if)#encapsulation pppoe
host1(config)#interface lag chicago.1
host1(config-if)#encapsulation ppp
host1(config-if)#ip address 10.10.1.1 255.255.0.0
As an alternative to using the command interface lag chicago.1 to configure the PPPoE
subinterface in this example, you can also use the command pppoe subinterface lag
chicago.1 to achieve the same result. For more information, see "pppoe subinterface lag"
on page 205.
The following example displays LACP configuration for two Fast Ethernet interfaces in
slot 3. The interfaces are enabled for active LACP. The speed and duplex characteristics
are the same for both interfaces.
host1(config)#interface fastEthernet 3/0
host1(config-if)#speed 100
host1(config-if)#duplex full
host1(config-if)#lacp active
host1(config-if)#interface fastEthernet 3/1
host1(config-if)#speed 100
host1(config-if)#duplex full
host1(config-if)#lacp active
The following commands add the Ethernet physical interfaces to a LAG bundle named
sunnyvale.
host1(config)#interface lag sunnyvale
host1(config-if)#member-interface fastEthernet 3/0
host1(config-if)#member-interface fastEthernet 3/1
The following commands configure a VLAN subinterface for the LAG bundle named
sunnyvale. In the LAG interface identification command (interface lag sunnyvale.1), the
number 1 represents the subinterface number for the VLAN subinterface.
host1(config-if)#encapsulation vlan
host1(config)#interface lag sunnyvale.1
host1(config-if)#vlan id 100
