[c-nsp] Qos between CE and PE

[Alexandre Snoeck]

I'm using this on a Cisco 2821 (revision 53.51) with 251904K/10240K bytes of 
memory with Version 12.3(8r)T7 IOS for the CE side and a Cisco 7206VXR 
(NPE-G1) processor (revision B) with 229376K/32768K bytes of memory with 
Version 12.3(4r)T3 IOS.

I'm still having some trouble with a basic config that doesn't work.

CE side
---------
class-map match-all FTP-server
 match access-group 110
!
policy-map FTP
 class FTP-server
  bandwidth percent 75
!
interface GigabitEthernet0/0
 bandwidth 10240
 ip address 192.168.100.1 255.255.255.0
 service-policy output FTP
 duplex auto
 speed 10


PE side
---------
class-map match-all FTP-server
 match access-group 110
!
policy-map FTP
  class FTP-server
  bandwidth percent 75
!
interface GigabitEthernet0/1
 bandwidth 10240
 ip address 192.168.100.2 255.255.255.0
 duplex auto
 speed 10
 media-type rj45
 no negotiation auto
 service-policy output FTP


Any ideas?


Alex
