  1. Hi Brendan, glad to hear you like it. Do you refer to rate-limiting on a router or switch?

    On routers you have the "rate-limit" command but it's the "legacy QoS" method of configuring policing, it can be applied inbound or outbound.

    On the Catalyst Switches (eg 3560) you can use the "srr-queue bandwidth limit " to limit outgoing traffic but I believe this is a shaper.

  2. This is one awesome posts about QoS policing and shaping .U don't find like this many out there.And I should thank U for this.
    BTW, I have few questions reg this,

    1.In this example that you have demonstrated on what basis the Tc (Time Interval) value was chosen. i,e 62.5 in this case ? (62.5 + 62.5 =125).Is there any logic behind it?

    Expecting the earliest reply..

    Thanks in Advance,

    Hi Rene,

    Excellent Article. As far as I know, no one has explained QoS this simply and nicely. Great Job!

    My only question is, if the Tc is reduced to 10 ms as you mentioned, will the data packets be fragmented? I always thought fragmentation happens only when the MTU is lesser than the packet size. Could you please throw more light on that.

    Thank you again for the great post.
