C3560-C bandwidth limiting

[LordDundy]

Hi,

I would like to start off by saying that I am no tech expert like many of your here and my question will probably seem very simple.

I have a 3560-C-8PC-S switch (15.2(2)E8 used in a home environment and I have a single goal:

I would like to limit the maximum up/download speed for a certain LAN port.

I have done my homework and Googled for days trying to understand the posts that to me seemed overly complex and most are described using Telnet connection. Although I can login via telnet, instead of the CLI I would like to doing everything through the Cisco Network Assistant app (v6.3).

While playing around with the QoS / Rate Limit functions I managed to find a way to throttle the download speed for LAN port 1. However, the upload was not getting throttled, it was still much higher speed than the download.

I would greatly appreciate the help of one of the many experts, if he/she could explain what needs to be done using the Network Assistant software to set this up properly.

Thank you so much in advance!

look again at your test and your configuration

your QoS rate-limit may only kick-in IF congestion occurs.

if no other traffic flows and there is enough bandwith available, QoS may still allow full speed for this traffic.

I am a complete novice when it comes to all this but done a few days of
Googling and trying to figure stuff out. Through that I learned that Rate
Limit only throttles the download speed of the port and does not throttle
upload speed at all.

Rate Limit throttles download speed accurately and constantly regardless the
load.

On another forum someone showed me how to set a policing rule that limits
the upload speed and this works fine:

ip access-list extended xxx
permit ip any any

class-map match-all limitport
match access-group name xxx

policy-map portlimit
class limitport
police 10000000 100000 exceed-action drop

interface GigabitEthernet0/1
service-policy input portlimit

look at this post 

in short: 

     for outbound you should be using srr-queue bandwidth limit 10 to limit the traffic to 10Mbps

     for inbound you need policing
