Dr.X · ‎01-18-2014

hi all

im trying to send radius attribute to vi access host on users of LNS router .

i finally succeded in sending it to (vi access x interface ) and it is ok ===> i mean that the command "service-policy output xxx" is seen under virtual-access xx interface .

but ...............................

i cant use traffic shape nor bandwith command inside this policmap !!!!

if inlcuded the shape or bandwidtht commands , the users that gave him the attribute cant be authenticated from radius and fail !!!!

it give me error 651 in ppp session .

i mean that i only can use "police cir "by policy map so that user success !!!

if i use bandwisht ot shape command , the user cant access and be authenticated !!!

the question is why ??

does pppoe adsl users cant be shaped by policy map ???

is it issue in ios ??

Hey

I use cisco 7206vxr with PPPoVPDN and i send rate-limit attributs to traffic shapping for each vi access with no problem.

i use 15.1M4 IOS

you can use cisco_av pair attributs to accomplish this and sending the rate-limit to each vi access.

Hope that can help you

regards

Dr.X · ‎01-22-2014

hi ,

thanks alot for reply ,

but .............

wt do u mean with rate-limit with shape ??

rate limit is considerrd as police

but shape is another issue , it is better than police becuase it buffer when there is congestion .

for me , rate-limit is fine without ptoblems , but

the problem is when we apply shaping on the vi acccess interface

the vi cant get the command policy map !!!

regards

Nidal Safadi · ‎01-22-2014

You don't need to applicy any policy-map

you just send the rate-limit attribut to the interface via cisco av pairs. this will make limits for your users based on their speeds category

i don't where is your problem ?

Nidal Safadi · ‎01-22-2014

Could you provide me how much PPPoVPDN users in one LNS you have?

Because i have this thread hope you help me too

hi ,

you are missunderstanding me

polic not equal to shape

i wish u google and find the difference between them

regards

Nidal Safadi · ‎01-22-2014

Listen, whatever what i understood, i think finally you need to limit download and upload for your PPPoVPDN customers? is this right ? then you can use what i mention above.

Tell me if am i right !!

regards

Dr.X · ‎01-22-2014

ohhhhh noooo ,

u still wrong !

uplad is not an issue to be enahced , the download bw is always congestion , so our work is only for download

regards

Nidal Safadi · ‎01-22-2014

OK, you need to limit ur users for their download speed, or download types ?

i think you need to make some qos for your users to make some pirorities to their traffic like voice,rtp, http ... etc ?
