Bandwidth Traffic Management

Hi,

i have got 1700 series internet router, gone threw several documents in cisco, was confused, so my requirement, i wanted to make use of 30% of HTTP traffic,50% of FTP traffic & rest traffic 20%, so any working configuration those who have already done can be more useful for me to go head in doing this for our internet router.

Re: Bandwidth Traffic Management

Hi Anand

Are you trying to configure QOS policy for the different classes of traffic ?

Yeah QoS policy only.

Re: Bandwidth Traffic Management

Cisco usually recommend that you reserve a minimum of 25% of your bandwith for the default class to handle all other network traffic, and a minimum 5% of bw for ip routing.

class-map match-any Network-Control

match ip dscp cs6

match ip dscp cs2

class-map match-any Critical-Data

match ip protocol http

match ip protocol ftp

policy-map Lan-Traffic

class Nework-Control

bandwitdh percent 5

class Critical-Data

set ip dscp af21

bandwidth percent 70

class class-default

bandwith percent 25

random-detect dscp-based

Use "max-reserved bandwith 100" to override the 75% default bandwith limit, then

Use "service-policy output Lan-Traffic" command on your serial interface to enable the policy-map from above, and

Use "show policy-map inteface xxx " to verify bandwith usage and hits.

Re: Bandwidth Traffic Management

Which specific commands that do not work? Maybe the 1700 series router doesn't have enough nvram to handle the qos, because I am implementing the similar qos in my routers (2800 series)...

Or you can try something like this..

class-map match-any HTTP-FTP

match access-group 110

policy-map LAN-TRAFFIC

class HTTP-FTP

bandwith percent 50

class class-default

fair-queue

access-list 110 permit tcp any any eq 80

access-list 110 permit tcp any any eq 21

access-list 110 permit ip any any
