about Cisco-AVPair attribute

[Tseveendorj]

Hello,

Sorry for asking cisco related thing.

What kind of Cisco-AVPair attribute's value to known for policy based 
shaping.
Currently I'm using following configuration with known Cisco-AVPair 
attribute's value ip:sub-policy-Out=1024Kbps,  ip:sub-policy-In=1024Kbps

policy-map 1Mbps
 class Match-Any-Packet
  police cir 1024000 bc 72000
    conform-action transmit
    exceed-action drop

So, I need to change the police to shape like below

Router(config)# *policy-map shape-cbwfq
*
Router(config-pmap)# *class cust1
*
Router(config-pmap-c)# *shape average 384000
*
Router(config-pmap-c)# *bandwidth 256
*

But I don't know what is the Cisco-AVPair attribute's value of shape ?

Sincerely,
Tseveen.
