Configure Profile Elements

Versa-logo-release-icon.pngFor supported software information, click here.

You use the Configure lifecycle to create all configuration objects for Secure SD-WAN deployments. The Concerto configuration objects are hierarchical. For more information, see Configuration Hierarchies.

The top level of the hierarchy consists of Profiles and Profile Elements. The Profiles hierarchy consists of Master Profiles and Subprofiles. For information about configuring profiles, see Configure Profiles.

Profile elements are reusable configuration objects that are part of all profiles. There are four types of profile elements:

  • Policies—You can configure the following types of policies for a profile element:
    • Application
    • Device Policies
    • Network Services
    • Security
    • User and Device Authentication
    • Routing
    • VPN
    • System
  • Policy elements—You can configure the following types of policy elements for a profile element:
    • Device
    • Network services
    • VPN elements
  • Rules—You can configure the following types of rules for a profile element:
    • Application
    • Security
  • Elements—You can configure the following types of elements for a profile element:
    • Application
    • Certificates
    • Endpoint
    • Monitor
    • Security (for Releases 12.1.1 and later)

Add a TCP Optimization Application Element

For Releases 11.3.1 and later.

TCP optimizations mitigate the effects of high latency and packet loss on the performance of TCP-based applications. The optimizations are based on a TCP proxy architecture in which one or more VOS devices in a network path between a client and server split the TCP connection into two. One connection faces the client and one faces the server, with the VOS devices acting as TCP proxies for each of the split network segments. The optimizations can be done in one of the following modes:

  • Dual-ended mode—TCP connection is split between two peer VOS devices in the network path
  • Single-ended mode—TCP connection is split independently on one or more VOS devices in the network path

After you create a new TCP optimization application element, you can use it when configuring traffic-steering rules.

To add aTCP optimization application forwarding profile element:

  1. Go to Configure > Profile Elements > Elements > Application.

    application-tcp-optimization-dashboard-left-nav-v2-border.png
     
  2. Select TCP Optimization Profile. The screen displays already configured TCP optimization profiles.

    application-tcp-optimization-dashboard-v2-border.png
     
  3. Click + TCP Optimization Profile. In the Create TCP Optimization Profile screen, enter information for the following fields.

    create-tcp-optimization-profile-v2-border.png
     
    Field Description
    Name Enter a name for the TCP optimization profile.
    Maximum TCP Send Buffer

    Enter the maximum size of the TCP send buffer. Setting the buffer size limits TCP memory consumption.

    Range: 64 through 16384 KB
    Default: 4096 KB

    Maximum TCP Received Buffer

    Enter the maximum size of the TCP receive buffer. Setting the buffer size limits TCP memory consumption.

    Range: 64 through 16384 KB
    Default: 4096 KB

    TCP Congestion Control

    Select the congestion control algorithm to use:

    • BBR congestion control algorithm—Bottleneck bandwidth and round-trip propagation time measures both the largest amount of recent bandwidth available to a connection and the connection's smallest recent round-trip delay. BBR then uses these metrics to control how fast it sends data and how much data it allows to be sent at any given time.
    • Cubic congestion control algorithm—An algorithm that uses a cubic function instead of a linear window increase function to improve scalability and stability for fast and long-distance networks. This is the default.
    • New Reno congestion control algorithm—An algorithm that responds to partial acknowledgments.

    Default: Cubic congestion control algorithm.

    TCP Loss Detection

    Select the method to use to detect TCP packet loss:

    • Duplicate ACKs—Loss detection based on duplicate acknowledgements. Duplicate acknowledgements mean that one or more packets have been lost in a TCP stream and the connection is attempting to recover them. They are a common symptom of packet loss.
    • Recent acknowledgment (RACK). RACK uses the notion of time, instead of packet or sequence counts, to detect losses.

    Default: Duplicate ACKs

    TCP Loss Recovery

    Select the method to use to recover lost TCP packets:

    • Pipe algorithm—Perform TCP loss recovery as described in RFC 6675. This is the default.
    • Proportional rate reduction—Perform TCP loss recovery as described in RFC 6937.

    Default: Pipe algorithm

    TCP Hybrid Slow/Start Click to enable TCP hybrid slow start. Hybrid slow start maintains the TCP slow-start mechanism, which probes network bandwidth and gradually increases the amount of data transmitted until it finds the network's maximum carrying capacity. It also provides a mechanism to help TCP slow-start to exit without incurring a large number of lost packets. By default, hybrid slow start is disabled.
    Default: Disabled
    Rate Pacing Click to enable rate pacing. Rate pacing injects packets smoothly into the network, thereby avoiding transmission bursts, which could lead to packet loss. By default, rate pacing is disabled.
    Default: Disabled
    Automatic Rate-Pacing Limit Click to enable rate pacing. Rate pacing injects packets smoothly into the network, thereby avoiding transmission bursts, which could lead to packet loss. By default, rate pacing is disabled.
    Default: Disabled
    Tags Enter one or more tags. A tag is an alphanumeric descriptor, with no white spaces or special characters, that you can use to search the objects.
  4. Click Next, or select the Permissions tab and update the permissions as needed.
  5. Click Save.

Configure Custom SD-WAN Security Profile Elements

For Releases 12.1.1 and later.

You can configure two types of custom SD-WAN profile elements:

  • Security actions—Allows you to choose the type of security action (such as cloud access security broker (CASB), decryption, and DNS) and the action to take on that type.
  • URL categories—Allows you to create a custom URL category by specifying a URL pattern and reputation, a URL string and reputation, and by uploading files in .csv format.

Note: You can configure URL categories and security actions as part of both SSE and SD-WAN services in Concerto. The configurations are common between the two services. If you configure URL categories and security actions for an SSE service, the same configuration appears in the SD-WAN service, and vice versa.

You can then use the security actions and URL categories when you configure security policies under Configure > Profile Elements > Policies > Security.

Configure Security Actions

To configure a security actions profile element:

  1. Go to Configure > Profile Elements > Elements > Security > Security Actions.
