Configuration Examples
Example 20-4 shows how to enable a PPPoE session on a GEC bundle:
Example 20-4 Enabling a PPPoE Session
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 Creates a GEC bundle.
Step 2 router(config)# lacp max-bundle 1-8 Sets the maximum number of active links per
GEC bundle. For PPPoE sessions maximum
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 Enables PPPoE session on the GEC bundle
subinterface.
global is the default group used when a
group name is not specified.
Step 7 router(config-subif)# end Exits to the global configuration mode.
