Bandwidth Guarantee SubInterfaces

[Fabien GRAGLIA]

i cheked differents solutions but that's not works. I'm searching to configure Bandwidth Guarantee on my fastethernet 0/1.2

class-map match-all TrfBWG

match input-interface FastEthernet0/0

!

!

policy-map TrfBWG

class TrfBWG

    priority 512000

!

policy-map PARENT

class class-default

    shape average percent 50

  service-policy TrfBWG

Return this Message, when i enter service policy PARENT output  command.

Insufficient bandwidth 1024 kbps for the bandwidth guarantee

// **** \\

interface FastEthernet0/0

ip nat outside

ip virtual-reassembly

rate-limit input 1024000 192000 384000 conform-action transmit exceed-action drop

rate-limit output 1024000 192000 384000 conform-action transmit exceed-action drop

duplex auto

speed auto

// **** \\

Who can help ?

(sorry for my english, i'm french)

I hope that's ok !

i think you cant use priority xxxx and percent in shaping together

try configuring priority percent instead of priority 512000

also by default you can only use 75% of the interface bandwidth so better you apply qos as below

priority xxxx

shape average XXXX (Rate to shape)

Ok, thanks, maybe can you help me ? i search a solution to implement bandwidth guarantee on my Subinterfaces 0/1.2.

How can i do it ?

i think i have a problem with queue limit :

Service-policy output: PARENT

    Class-map: class-default (match-any)

      5064 packets, 4956870 bytes

      5 minute offered rate 66000 bps, drop rate 0 bps

      Match: any

      Queueing

      queue limit 64 packets

      (queue depth/total drops/no-buffer drops) 0/0/0

      (pkts output/bytes output) 5064/4957294

      shape (average) cir 1000000, bc 4000, be 4000

      target shape rate 1000000

      Service-policy : TrfBWG

        Class-map: TrfBWG (match-all)

          5055 packets, 4956294 bytes

          5 minute offered rate 66000 bps, drop rate 0 bps

          Match: input-interface FastEthernet0/0

          Queueing

          queue limit 64 packets

          (queue depth/total drops/no-buffer drops) 0/0/0

          (pkts output/bytes output) 5055/4956718

          bandwidth 25% (250 kbps)

        Class-map: class-default (match-any)

          9 packets, 576 bytes

          5 minute offered rate 0 bps, drop rate 0 bps

          Match: any

          queue limit 64 packets

          (queue depth/total drops/no-buffer drops) 0/0/0

          (pkts output/bytes output) 9/576

Also you have policing configured on FA0/0 which seems to be your outgoing interface to internet.

You will need to explain what you need to achieve and explain the whole scenario ... that would help to compile the commands for your configuration.

So; i want to give bandwidth guarantee (512 k) on my subinterface FE 00/1.2, where bandwidth on my FE 0/0 (Internet access) been 2M.

it's possible ?

thanks again, sorry for my bad communication.

actual config :

policy-map TrfBWG

class TrfBWG

    bandwidth percent 25

policy-map PARENT

class TrfBWG

    shape average 1000000
