IPSLA

     

    The IPSLA is a technology for Cisco devices which will help you in monitoring VOIP traffic, Video traffic and WAN availability. This setting option allows you to create an set the threshold settings for VOIP, WAN and video monitors under below tabs:

    1. VoIP call Settings

    2. VoIP Threshold Settings

    3. WAN Threshold template

    4. WAN Test Parameters

    5. Video Call Settings

    6. Video Threshold template.

     

    VoIP Call Settings

    Defining Call Settings:

    Define a template with the required VoIP settings to be used for monitoring performance. The VoIP template comes with pre-populated default values. Incase you would like to effect some changes to the values before initiating monitoring, make the changes by defining the below parameters:
     

    Destination Port - Specify the VoIP UDP port to which VoIP Monitor sends simulated traffic to generate performance metrics. The default port number is set as 16384. You can specify a port in the range of 16384 - 32766.

    Simulated VoIP Codec - The VoIP jitter codec decides the type of traffic that VoIP Monitor simulates over your network.

    Operation Frequency - The operation frequency is the frequency with which QoS metrics are collected by the IP SLA agent on your network to determine performance.

    Operation Timeout - The operation timeout is time to wait for the response from the responder / destination device in msecs.

    Type of service - The Type of Service octet allows you to set precedence levels for VoIP traffic of the IP SLA operations.

    MOS Advantage Factor - The advantage factor is a measure, on a scale of 0 to 20, of the willingness of your VoIP network users to trade call quality for convenience

     

    VoIP Threshold Settings

    Defining Thresholds for the monitored parameters:

    You can define a threshold template so that the VoIP performance parameters can be better suit your company SLA's (Service Level Agreements). Alerts are triggered based on the thresholds configured so that you can take corrective actions in time. Please configure the below parameters:


    MOS Threshold : Configure the MOS threshold by specifying the upper and lower MOS range values in the range of 1 to 5.

    Jitter Threshold : Configure the jitter threshold in msecs with upper and lower threshold limits. The range is from 0 to 6000 msecs.

    Latency Threshold : Specify the delay allowed in msecs again in the range of 0 to 6000.

    Packet Loss : Specify the number of packets that can be lost in transit.

    Notification Profile : Select the required notification profile(s) in order to notify when the any threshold rule is violated.

     

    WAN Threshold Settings

     
    NetFlow Analyzer generates alerts when threshold levels are violated. The threshold template is assigned default values in NetFlow Analyzer. In order to customize the threshold parameters, to suit your requirement, you can Configure the upper and lower threshold limits for round trip time the range being 0-60000 milliseconds and set this limits to the available Notification Profiles by selecting the available profiles to the right box.

     

    WAN Test Parameters

    NetFlow Analyzer uses a set of test parameters like payload, type of service(ToS), frequency and timeout for monitoring WAN performance. The test parameters are assigned default values in NetFlow Analyzer. In order to customize the test parameters, to suit your requirement, do the following. 

    Edit the following fields according to your requirement.

    • Payload: The default value of payload is 24 bytes. Specify an echo payload value between 0 to 3000 bytes.
    • ToS : The default value of ToS is 30. you can specify any echo ToS value between a range of 0 to 255 .
    • Frequency: The default value of operation frequency is 60 seconds. You can specify any value between a range of 0 to 604800 msecs
    • Timeout: The default value of operation timeout is 60 seconds.You can specify the timeout between a range of 0 to 604800 seconds

     Click "Save" to save the changes.

    Note: The timeout interval value

     

    Video Call Settings

    Define a template with the required video settings to be used for monitoring performance. The video template comes with pre-populated default values. Incase you would like to effect some changes to the values before initiating monitoring, make the changes as follows:

     

    Destination Port - Specify the video UDP port to which video Monitor sends simulated traffic to generate performance metrics. The default port number is set as 16384. You can specify a port in the range of 16384 - 32766.

    Profile Name - The type of basic video profile for the IP SLAs operation being configured. 

    Operation Frequency - The operation frequency is the frequency with which QoS metrics are collected by the IP SLA agent on your network to determine performance.

    Operation Timeout - The operation timeout is time to wait for the response from the responder / destination device in msecs.

     

    Video Threshold Settings

     

    You can define a threshold template so that the video performance parameters can be better suit your company SLA's (Service Level Agreements). Alerts are triggered based on the thresholds configured so that you can take corrective actions in time. Here are the steps to define a threshold template:

    Configure the following values:

    Jitter Threshold : Configure the jitter threshold in msecs with upper and lower threshold limits. The range is from 0 to 6000 msecs.

    Latency Threshold : Specify the delay allowed in msecs again in the range of 0 to 6000.

    Packet Loss : Specify the number of packets that can be lost in transit.

    IA Jitter: Configure the IA jitter threshold in msecs with upper and lower threshold limits. The range is from 0 to 6000 msecs.
