Hi All,

I'm working for an service provider. I need to know is there any option/feature in radius thru which I can inform the NAS device to control bandwidth for a particular dsl users.

Ex: The ADSL-Router(NAS) device sends the username/pwd to the accounting&radius software which verifies the credentials. I have seen some radius attributes in my billing software. Is there any option in radius attributes which will inform the router after authentication that this user's bandwidth shouldn't exceed some limit.

Or is there any other way to limit the bandwidth per user basis.

You need to define following AV pair in the RADIUS profile


cisco-avpair = "ip:sub-policy-In=CUST_BW_pkg_1_IN"

then RADIUS will pass those two policy map names as subscribers inbound& outbound policies.

So you need to have a policy map define in the ISG to match these lists you are getting from the RADIUS. such as following

policy-map CUST_BW_PKG_1_OUT

class class-default

shape average 1024000

policy-map CUST_BW_pkg_1_IN

class class-default

police 128000

this will result 1MB downlink & 128 uplink for the customer
