[rbak-nsp] Link Group - Access with PPPoE

Ran into an unexpected issue with link grouping access ports with pppoe.
I'm using identical gig-4 cards which are capable of 8192 sessions each.
I've linked across two cards, but it seems the system duplicates the session
on each card in the link-group.  Is this expected behavior or could
something be misconfigured?  You can see what I mean below on cards 1 and 2.

 

Max Circuits:  1:  8192,   2:  8192,   3: 16384,   4:  8192,   5:     0,

               6:     0,   7:     0,   8:     0,   9:     0,  10:     0,

              11:     0,  12:     0,  13:     0,  14:     0,

              11:     0,  12:     0,  13:     0,  14:     0,

 

Num Circuits (OTHER):

               1:  6630,   2:  6629,   3:    47,   4:   938,   5:     3,

               6:     4,   7:     3,   8:     3,   9:     3,  10:     3,

              11:     3,  12:     3,  13:     3,  14:     3,

 

Num Circuits (TOTAL):

               1:  6630,   2:  6629,   3:    47,   4:   938,   5:     3,

               6:     4,   7:     3,   8:     3,   9:     3,  10:     3,

              11:     3,  12:     3,  13:     3,  14:     3,

 

.but there aren't that many sessions up:

 

               NUMBER

CIRCUIT TYPE   CIRCUIT     UP      DOWN

------------   -------   ------   ------

ATM            23          23         0

ETHERNET       0           0          0

DOT1Q          7553        7553       0

Total circuits: 7576  up: 7576  down: 0

 

 

Here's the config:

!

link-group ppp1 access

encapsulation dot1q

dot1q pvc on-demand 2000 through 2050 encapsulation pppoe

  idle-down 60

  bind authentication pap chap maximum 8000

maximum-links 8

lacp passive

!

port ethernet 1/3

description ppp

no shutdown

encapsulation dot1q

link-group ppp1

!

port ethernet 2/3

description ppp

no shutdown

encapsulation dot1q

link-group ppp1

!

 

Thanks!
