What is the best method for guaranteeing bandwidth to an internal host through a router? I would like to use the internet facing interface and apply an input service-policy map. However, it looks like I can't do that, as I get "...not supported in input policy."
Basically I want to use a policy-map to set a guaranteed min. bandwidth of 20000 to a host defined in a class-map, and then apply that service-policy to an interface's input.
There a better way?
Doesn't make sense to do it on the inside interface as an output.
Thanks.

Hello,
What is the platform/IOS you are referring to?

Hi
First, can you show us what was your policy-map and the class-maps? This will help us find why it is not. Supported
Second, the best way depends on why do you need it, if you need to give more download rate to this host then i think you need your ISP apply the policy-map on his router, because applying on on your router will be useless as the router is at your end of the circuit
But if you need to give more upload bandwidth to this host, then you can either put it in the ingress port or the egress with inbound or outbound direction

This is a 2921 router running IOS 15.1(2)T1.
Here are the commands -
access-list 101 permit ip any X.X.X.8 any
class-map CENTRAL
match access-group name CENTRAL
policy-map web_conferencing
class CENTRAL
bandwidth 20000
class class-default
fair-queue
interface gig0/0
service-policy input web_conferencing

Can you try to remove "fair-queue" from the class-default?
in code 15.X, WFQ are no longer supported, please check and let me know if that works.
Thanks

This is how it looks now -
class-map match-all CENTRAL
match access-group name CENTRAL
!
!
policy-map web_conferencing
class CENTRAL
bandwidth 20000
And this is what happens when I try to apply it-
(config-if)#service-policy input web_conferencing
Weighted Fair Queueing feature not supported in input policy.
Bandwidth command not allowed at parent level in input direction

Have you able to fix this ? . I'm also having same issue
platform is 881 with c880data-universalk9-mz.154-3.M4.bin

and forgot to mention, queing only done on egress
if you want to use it on ingress direction, then you have to use policing, it will help you but this will be more complicated

Okay, I'll take a look at policing. Thanks Amjad!

QOS has the following sequance of operations:
Classify-Mark-Bandwidth and priority.
Classify is a load on the processor and better to be done while the packet input to the network.
So, it is applied on input interface. It could be applied on output also to deal with different WAN technology (ATM & MPLS for example).
And hence it mark the packet
Bandwidth and Priority by logic is to be done on the output interface.
The router may has more than one interface with different speeds
Hence, each class will have different bandwidth on each interface.
