interface Port-channel32
no ip address
no negotiation auto
lacp max-bundle 1
lacp fast-switchover
!
interface Port-channel32.1
encapsulation dot1Q 10
pppoe enable group bba_group_1
!
interface Port-channel32.2
encapsulation dot1Q 20
pppoe enable group bba_group_1
!
Command Purpose
Step 1
router(config)# interface port-channel number

number of active links is one.
Step 3
router(config)# lacp fast-switchover
Retains PPPoX sessions incase of member
link switchover.
Step 4
router(config)# interface port-channel
subinterface
Creates a GEC bundle subinterface and
enters the subinterface mode.
Step 5
router(config-subif)# encapsulation dot1Q
vlan-id
Enables IEEE 802.1Q encapsulation of
traffic on a specified subinterface in a
VLAN. Specify the VLAN identifier.
Step 6
router(config-subif)# pppoe enable group global
