QoS per IP

Answered Question
Jan 19th, 2009

Hello,

how can I limit the bandwidth for some IPs ?

class-map match-any R5

match access-group 170

policy-map RR5

class R5

bandwidth 800

intterface FastEthernet1

service-policy output RR5

access-list 170 permit ip 172.31.5.0 0.0.0.255 any

Note: R5 = 172.31.5.0/24

Is this enough for limiting network 172.31.5.0/24 bandwidth to 800 kbps ?

I want to limit all the traffic.

thank U!

I have this problem too.

Hi Spinu,

The "bandwidth" command under class R5 sets the minimum guaranteed bandwidth (NOT the maximum bandwidth) for the traffic classified by acl 170.

Instead of the bandwidth command you should use shaping or policing under class R5:

shape average 800000

or

police 800000 conform-action transmit exceed-action drop

Cheers:
