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.
