Re: [c-nsp] ME3400E - Shaping vlans?

2013-09-26 Thread Pavel Skovajsa 
Per Vlan Egress Shaping and Per vlan Ingress policing is definitely
possible but not straightforward to configure since there are many
limitations.For example you can't have a match vlan in output policy-map
and you need to match against DCSP. For example:

class-map match-any Video
match ip dscp af41
match ip dscp cs4
class-map match-any Voice
match ip dscp ef
match ip dscp cs5
class-map match-any Mng
match ip dscp af21
match ip dscp cs2

policy-map 33Mps
  class Voice
shape average 1024000
queue-limit 150
  class Video
shape average 2000
queue-limit 150
  class Mng
shape average 1024000
queue-limit 150
  class class-default
shape average 
queue-limit 272
So you would need an input policy map that allows match vlan and set dscp
on that one. There are many more combinations that work, and many that
don't (priority,bandwidth,shape).

The best is to study the QoS guidelines for this platform. below are some
resources for ME3400:

 dot1q protocol but havent seen any practical examples/applications...

[c-nsp] ME3400E - Shaping vlans?

2013-09-25 Thread CiscoNSP List 
Hi,

Is it possible to shape vlans on the ME3400E? (i.e. Multiple vlans on a trunk 
port, shaping them at different speeds)?

Ive tried the following (unsuccessfully):

class-map match-all vlan10 


match vlan 10 


policy-map VLAN10_10Mb 


class vlan10 


shape average 980 


Switch(config)#interface GigabitEthernet0/1
Switch(config-if)#service-policy output
VLAN10_10Mb 


Match vlan is not supported for this
interface 



 

policy-map VLAN10_10Mb 


class vlan10 


shape average 980 


policy-map parent 


class vlan10 


service-policy VLAN10_10Mb 


Switch(config)#interface GigabitEthernet0/1 


Switch(config-if)#service-policy output
parent 


QoS: Configuration failed. Only class-default
is allowed in top level of an output policy

Cheers.
