3550 rate limit per port

[swilk]

I am trying to figure out how to limit each port on a 3550 to have no more than 2meg of upload or download bandwidth. I currently have 75 of these switches deployed in the University dorms and am needing to better control over bandwidth utilization. I have read and researched everyhting I can find and nothing seems to work. Here is a base port configuration that I use:

switchport access vlan 60

switchport mode dynamic desirable

speed 100

duplex full

spanning-tree portfast

Could someone please post what port configuration should be used to accomplish port rate limiting? All of my users rely on DHCP for addresses.

Hi,

i would recommend policy maps. The problem is that they limit only incoming traffic. The configuration is very easy:

mls qos

!

class-map match-all Rate_incoming

match access-group 1

!

policy-map Rate

class Rate_incoming

police 1000000 10000 exceed-action drop

!

interface FastEthernet1/0/1

service-policy input Rate

!

access-list 1 permit 10.1.0.0 0.0.255.255

access-list 1 permit 192.168.20.0 0.0.0.255

The complete description you can find in the configuration guide:

We have already found that out on how to limit the incoming, we also want to limit the outgoing as well. Does anyone have any pointers on that?
