The QoS traffic shaping and shaping tip

Hello

Could someone tell me what is the difference between traffic and shaping of edge smoothing?

Kind regards.

The main reasons to use the traffic shaping are to control access to the available bandwidth to ensure that traffic is consistent with specific policies and to regulate the flow of traffic to avoid congestion. Some reasons for example for the use of the following traffic shaping:

Control access to bandwidth when the policy dictates that the average rate of a given interface must not exceed a certain rate.

Configure traffic on an interface if you have a network with different access rates. Suppose that one end of the link in a frame relay network runs at 256 Kbps and the other end of the link works to 128 Kbps. sending packets to 256 Kbps may cause applications to stop using the link.

A similar and more complex case would be a network of link layer giving indications of congestion on the terminal equipment of data access with different rate attached devices (DTE). The network may be able to deliver more speed transit to a DTE device to a precise moment than at any other time.

If you offer a service of low speed, the traffic shaping allows you to use the router to partition your T1 or T3 links into smaller strings.

The traffic shaping prevents packet loss. Its use is especially important in Frame Relay networks, because the switch cannot determine which packages have priority or what packages should be removed in the event of congestion.

Specifying the rate of advanced formatting allows you to make better use of available bandwidth by allowing more data than the EIF to be sent if the bandwidth is available.

  • When I put the traffic shaping that I lose my VLAN ID, how I can I put both?

    Foreach ($PG in ($VMHost |)) Get-VirtualSwitch-name "vSwitch0 | (Get - VirtualPortGroup))

    Just copy the value of the $PG variable, and you should be ok.

  • The configuration of the coast DMVPN speaks with higher bandwidth for traffic shaping

    Dear all,

    We have the unusual situation that on our sites talking DMVPN has a higher bandwidth (33 Mbps) that our

    DMVPN Hub Site.

    Therefore, we must apply to 10 Mbps on the interface of tunnel on the radius of traffic shaping.

    The following link describes only how to make an application in the form at the end of the hub, but not on the site of end spoke:

    http://www.Cisco.com/en/us/docs/iOS/sec_secure_connectivity/configuration/guide/sec_per_tunnel_qos.PDF

    How to proceed with this on the router spoke?

    Creating a service policy and applying then to the tunnel interface will do the job? Put in shape will be before or after encrypting the traffic?

    And then we would need to increase the buffer size of 1024 to something more replay window?

    The following example would work? We would apply the outbound policy to the Tunnel interface:

    class-map match-any CLASS_ANY
     match any 
    policy-map POLICY_SHAPE10MEG
     class CLASS_ANY
      shape average 10000000

    interface Tunnel 0
    service-policy output POLICY_SHAPE10MEG

    Thanks for your help,

    Thorsten

    I see on the hub strategy is applied successfully on the tunnel. The political POL_SHAPE10MEG is applied on the tunnel you wanted, this way the rays won't be able to consume even if the bandwidth of the hub it has higher bandwidth.

  • Question about [credits] traffic shaping

    I'm working on how the work of traffic shaping, but the manuals only speak of credits but not the case of the examples.

    Have a virtual machine and put it on his own group of ports [VM], with the following parameters:

    Average bandwidth: 10000 Kbps

    Bandwidth: 25000 Kbps

    Burst size: 4096 KB

    -How to get credits [I understand that it adds when the virtual machine uses less bandwidth medium, and that is the credit in figures, kbits or time to burst?

    -Assumes that the virtual machine is have a download started for a certain period of time, will it start to average speed, then go directly to the break-up and for how long, when he gets back to bandwidth? Sorry so many questions... I find it very difficult to know the other then by testing this operation, could someone shed light on this please?

    Thanks a lot for your precious time.

    Concepts of traffic shaping:

    • Average bandwidth: target traffic rate cap that is trying to enforce the switch. Whenever a customer uses less defined average bandwidth, credit accumulates.
    • Bandwidth: additional bandwidth available, above average bandwidth, for a short burst. The availability of the burst depends on credit accumulated so far.
    • Size of Burst: amount of traffic that can be sent or received at top speed. By combining the bandwidth and burst, you can calculate the maximum time allotted for the rafale.

  • Traffic Shaping to cap bandwidth

    Hi all, I have a question about the port groups and traffic shaping.

    Say I have a 10 GB uplink on my for use by VMs esx server and the server will host computers 10 virtual. I want to limit the bandwidth of each VM usage to 1 GB. If I understand correctly the VMware networking concepts to do this I create a vSwitch and assign the 10 GB uplink. Can I create a group of ports and set the average maximum burst setting to 1 GB.  As I deploy each VM I would attribute the Group of ports on the virtual network adapter in the virtual machine.  Each VM would then receive the 1 GB traffic shaping parameters.  Is this fair?

    I was a little unsure as to if just ports group provides the parameters for each card virtual network of port assigned to the port group or if the Group of port traffic shaping parameter represents the total amount of bandwidth available for virtual computers assigned to the port group.

    If just ports group provides the parameters for each port of the virtual network card then each VM would be capped at 1 GB.  Otherwise, I guess that if the Group of port traffic shaping parameter represented the total available bandwidth in assinged of VMs for the Group of ports, I would need to create a group of ports for each VM I wanted to cap at 1 GB. 10 mV and 10 port groups to 1 GB each... that doesn't seem fair.

    Someone at - it glimpse of this?

    Thank you

    Port groups provide cap to each virtual NETWORK adapter - so each bound traffic VMs will be capped at 1 GB - but don't forget if you add another group of this virtual switch ports, that these virtual machines network traffic will not be bound by the settings applied to this port group.

  • Traffic Shaping for virtual machines

    I'm looking to implement a virtual machine of traffic shaping, and I'm getting something unexpected. I put on the vSwitch 102400 Kbps to max out at 100 MB of traffic shaping. However, on the comments, I see the speed of the network as 1 GB. I tried to disable and re-enable the network connection, and even restart the guest but it still says 1 GB. I thought when I did in the past, it showed as a speed lower than the guest. I'm wrong, or am I missing a step somewhere?

    No, you're not wrong - the operation will always identify the virtual NETWORK card as a card of 1 GB netowrk traffice shaping will be accomplished by the virtual switch for limiting outgoing traffic to a maximum of 100 MB.

    Thanks in advance

    Rogerio

    Unfortunately, there is not a complete list of the different OID in different MIB. In order to find this info to simply browse through the different MIB seeking the OID, you need. We did some looking through the MIB and found these OIDs that can help you. Another thing to keep in mind is that the MIB downloaded are in general of a group of switches. So there are situations where a /OID MIB listed will work for a certain model of switch with certain level of firmware.

    RMON-MIB

    Another method, some people have had success, done using a SNMP walk.
