ME3400E traffic policing and shaping config

Julie Tupling

I need to configure traffic policing and shaping to a vlan on our ME3400E switches - Is this the correct way to do it?

I could make policies for each customer, but to me it makes more sense to make one for the bandwidth needed - am I looking at this correctly?

policy-map 30MEG

class class-default

    police cir 30000000

      conform-action transmit

      exceed-action drop

policy-map SHAPE30MEG

class class-default

    shape average 30000000

interface GigabitEthernet0/1

switchport access vlan 101

switchport mode dot1q-tunnel

service-policy input 30MEG

service-policy output SHAPE30MEG

Thanks,

Julie

Hi Julie,

Are you trying to police all Customers on a port or only one?

In your example, you policing an access port which is essentially one customer.

Perhaps you can share what exactly you trying to achieve.

Rgds.

We are using one port per customer for our MetroEthernet platform except on the trunk ports, so shaping and policing on the access port should be all we need - I shouldn't have said per VLAN.  I meant per port.

Thanks,

Julie

Ok, makes sense then. In future, you will need to consider an HQOS PMAP model if your customer wants to start splitting that 30Mb into different classes. It really helps when have multiple customers on the same device (meb).

I found that smaller (sub-50Mb) egress shapers don't want to work on 1Gb UNI's on the EG Series. It gives me a "configuration must be within 1% of etc..." error. To get smaller I actually needed to step the interface down to 100Mb to get to a 5Mb shaper to work.

Did the switch except your 30Mb egress PMAP? I was using 12.2(50)SE4.

We are not going to  do any class based QoS - at least not at this time. 

When you mention that you had to step the interface down to 100MB - How do you do that?

The switch did accept the commands that I copied into my original post.  I didn't get any errors . . .

Interesting about the PMAP. Which IOS are you using?

I used the speed and duplex command under the interface.

All the interfaces on the ME3400's are 10/100/1000 based ports. The GLC-T's and LH's allow speed scaling.

Hashiem,

How do you do spped scaling on the LH ports - when I tried to configure the port speed - the only options are negotiate or  nonegotiate

Thanks,

Julie

Julie,

Apologies for the delay in response.

You correct, my mistake. The LH only allows for auto speed stepdown. Manual works on the GLC-T with the media-type RJ-45.

We do have 100M and 10M connections on UNI SFP interfaces due to successfull autogotiation with customer kit.
