Bandwidth restrictions on 877

Answered Question

We have a client who is using a Cisco 877 for internet access (via ADSL - 8Mb down, 0.8Mb up) for both their Corporate staff and their Guest network. They have come to us with a requirement that the Guest network should never have more than 1Mb (down) of bandwidth.


What would be the best way to implement this?


Sanitised config attached: note that the only reason I'm using BVI interfaces is that the config is on an 877W and I'm testing on an 877!

You can attach a service-policy on the BVI that is for that particular dot11radio interface trunk for Guest SSID.


Example:

interface BV2:

service-policy input QoS_In_BVI2

service-policy output QoS_Out_BVI2


policy-map QoS_In_BVI2

class class-default

police 150000


policy-map QoS_Out_BVI2

class class-default

police rate 500000


You can adjust the rate value to what you want:

Target Bit Rate (bits per second)


  • 1
  • 2
  • 3
  • 4
