Hi,

Then bandwidth limit command will limit the bandwidth of the interface specified as percentage along with the command. So in order to limit the bandwidth ot 30 Mb on a 100 Mb interface please use srr-queue bandwidth limit 30 under the interface. Also it seems you have already enabled mls qos globally ( this is needed).

Dear Friend,

I configure "mls qos" command in global mode Cisco 3750 switch and then apply "srr-queue bandwidth limit 70 on int fas0/2

but bandwidth exceed more than 40 mb.

I need 30 mb bandwidth limit on int fast 0/2

swtich(config)#mls qos

switch(config)# int fas0/2

switch(config-if)#no switchport

switch(config-if)# ip add 192.168.1.1 255.255.255.0

switch(config-if)#srr-queue bandwidth limit 70

but still bandwidth exceed more than 40 mb through fas0/2 interface

what config i need to achive this

Thanks in ADV,

You need to run "srr-queue bandwidth limit 30" on interface to limit the bandwidth to 30Mbps
