Juniper JUNOSE 11.1.X - LINK LAYER CONFIGURATION 4-7-2010, Configuration Manual

Page: 241 / 774

Example: Configuring a PPPoE Subinterface over a VLAN for a LAG Bundle
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
The following commands configure a PPPoE subinterface over the VLAN subinterface
for the LAG bundle named sunnyvale. In the LAG interface identification command
(
interface lag sunnyvale.1.2 ), the number 2 represents the subinterface number for
the PPPoE subinterface.
host1(config-if)# encapsulation pppoe
host1(config)# interface lag sunnyvale.1.2
host1(config-if)# encapsulation ppp
host1(config-if)# ip address 10.10.2.2 255.255.0.0
As an alternative to using the command interface lag sunnyvale.1.2 to configure
the PPPoE subinterface in this example, you can also use the command pppoe
subinterface lag sunnyvale.1.2 to achieve the same result. For more information,
see “pppoe subinterface lag” on page 207.

The following example displays configuration of LACP for two Fast Ethernet interfaces
in slot 5. The interfaces are enabled for active LACP. The speed and duplex
characteristics are the same for both interfaces.
host1(config)# interface fastEthernet 5/0
