Configuring Hierarchical Rate-Limit Actions (SRC CLI)

 

You configure parent groups to create a hierarchy of rate-limits actions.

The type of action that you can create depends on the type of policy rule. See Policy Information Model.

Use the following configuration statements to configure rate-limit actions:

To configure a parent group:

  1. From configuration mode, create a parent group in a policy list—for example, PGShared.

  2. Configure a rate limit for the parent group.

    • Specify that the rate limit is either one rate or two rate. The rate-limit type determines the options that you can configure for a rate-limit action.

    • (Optional) Configure the target rate for the traffic that the policy covers.

    • (Optional) Configure the amount of bandwidth allocated to burst traffic in bytes.

    • (Optional) For two-rate rate-limit profiles, specify the amount of bandwidth allocated to excess traffic flow over the committed rate.

    • (Optional) For two-rate rate limit profiles, specify the amount of bandwidth allocated to burst traffic in excess of the peak rate.

    • (Optional) For one-rate rate limit profiles, specify the amount of bandwidth allocated to accommodate burst traffic.

    • (Optional) Set the rate-limit to color aware for the rate-limit to process color values set in the TOS byte of the packet header.

  3. (Optional) Configure the rate-limit actions for traffic flows that:

    • Do not exceed the committed rate and burst size

    • Exceed the committed rate but remain below the peak burst size

    See Configuring Types of Actions for Rate-Limit Actions (SRC CLI).

  4. Enter a description for the parent group.

  5. Step up one level in the edit hierarchy.

  6. (Optional) Configure the parent group to reference an external parent group. For example, to add a reference called epg1-ref:

    • Specify the name of the external parent group that you want to reference. For example, to reference the external parent group epg1:

    • Specify the name of the hierarchical policy parameter for the external parent group. For example, to associate the hierarchical policy parameter called hpp1:

    • Specify the attributes of the hierarchical policy parameter that you are referencing.

      For information about configuring the attributes of the hierarchical policy parameter, see Configuring Hierarchical Policy Parameters for External Parent Groups (SRC CLI).

  7. (Optional) Return to the rate-limit action configuration and verify the configuration.

  8. (Optional) Create another parent group within this parent group. For example:

  9. (Optional) Follow the instructions in this procedure for configuring the parent group.
