Help With Bandwidth Shaping

[Louis Adams]

Hi,

I am setting up layer 3 switching for AT&T Network on Demand.  I have a 3650.  I have made an EVC in the AT&T Cloud for 200Mb speed.  In the little documentation I have it says i need to shape the bandwidth of the interface to match.  It is currently a 1 gig port.  Leaving everything at default I am getting about 20 Mb download.  way off.  If I make the port 100 with the speed command.  I am getting 100Mb download.   So I am assuming that I need to shape the port to 200Mb.  

I tried creating a policy map below

policy-map SHAPE-200M
class class-default
shape average 200000000

Then on the interface i put

service-policy output SHAPE-200M

this seems like it has no effect.  Am i missing something.  This is first time using this and the switch is pretty much out of the box.

Hi Louis,

A couple questions:

1. Can you confirm that your interface is operating at 1000Mbps with "show interface"?
2. Can you please post a copy of your interface configuration?

[Louis Adams]

Yes,

The interface is 1 gig.  That is why I need to lower it to 200MB.  If I lower it to 100MB by issuing the speed command "speed 100" I get a boost and get 100MB through the AT&T Cloud.  I am trying to get 200MB which is what is provisioned.  So the port has to be set at 1 gig.

Hi Louis,

Can you please post your interface config?

Are you using a routed interface or an SVI?

[Louis Adams]

Sorry for the late response I am actually traveling and setting sites up on the new network.  I am hard coding he ports for speed 100 and duplex full.  Yes these are SVI's .Below is the interface config

interface GigabitEthernet1/0/1
 description LINK TO CYRUSONE
 switchport access vlan 100

 speed 100
 duplex full

when I try to shape it it looks like this

interface GigabitEthernet1/0/1
 description LINK TO CYRUSONE
 switchport access vlan 100
 speed 1000

duplex full

service-policy output SHAPE-200M

Hi Louis,

Can you post the output of the command "show policy-map interface GigabitEthernet1/0/1" when you are trying to transfer data at a high rate through that port?

Can you also post the output of "show interface GigabitEthernet1/0/1"?
