[rbak-nsp] rate limit

[Илья Савин]

Hi,

I try to limit bandwidth on PPPoE sessions with policy policing and policy
metering. 

[local]Redback#sh conf qos
Building configuration...

Current configuration:
context local
!
qos class-map classmap1 ip in
!
!
!
context local
!
 policy access-list SERVICE_out
  seq 10 permit ip any any class SERVICE1
!
! ** End Context **
!
qos policy inet metering radius-guided
 rate 1000 burst 100 counters
 access-group SERVICE_out local
  class SERVICE1
!
qos policy pinet policing radius-guided
 rate 1000 burst 100 counters
 access-group SERVICE_out local
  class SERVICE1
!
end

When user connected, I see:

[local]Redback#sh qos circuit detail
Circuit: 2/2 vlan-id 1016 pppoe 45

Policy Name       : pinet
Policy Type       : policing
Hierarchical Type : None
Rate              : 8000              Rate Source       : radius

Class mapping     : 1-->0, 2-->0, 3-->0, 4-->0, 5-->0, 6-->0, 7-->0, 8-->0

Policy Name       : inet
Policy Type       : metering
Hierarchical Type : None
Rate              : 8000              Rate Source       : radius
Burst             : 1000              Excess Burst      :
Class mapping     : 1-->0, 2-->0, 3-->0, 4-->0, 5-->0, 6-->0, 7-->0, 8-->0

Limits set to 8 Mbit/sec. But real transfer speed ~25 kbyte/sec. If I chande
Rate and Burst values, real speed changes too. But it always much lower,
than expected.

Please, help me with this problem.

Best regards,
