Configuring Port Channel Dynamic Load Balancing

This procedure shows you how to configure port channel dynamic load balancing. You can perform this configuration starting from the 6.1.2 release.

Before you begin

• The Cisco ACI fabric is installed, the Cisco APICs are online, and the Cisco APIC cluster is formed and healthy.
• A Cisco APIC fabric administrator account is available that will enable creating the necessary fabric infrastructure configurations.
• The target leaf switch and protocols are configured and available.

Procedure

Step 1

Configure port channel dynamic load balancing policy.

Example:

<infraInfra> 
    <lacpLagPol annotation="" ctrl="fast-sel-hot-stdby,graceful-conv,susp-individual" descr="" dn="" maxLinks="16" minLinks="1" mode="active" name="107_pc4" 
    nameAlias="" ownerKey="" ownerTag="" pcLB="dynamic" userdom=":all:common:"/>  
</infraInfra> 

Step 2

Set the Flowlet Aging Time, DRE thresholds, DLB Mode, and Fabric Port DLB configurations.

Example:

<infraInfra dn="uni/infra">

    <topoctrlDynamicLoadBalancingPol dn="uni/infra/dlbpol-dlbpol1" flowletAgingTime="500" dreThresholdLevel1="5" dreThresholdLevel2="5" dreThresholdLevel3="10" dreThresholdLevel4="15" dreThresholdLevel5="15" dreThresholdLevel6="25" dreThresholdLevel7="25" dlbMode="flowlet" fabricPortDlbMode="disabled" >

    </topoctrlDynamicLoadBalancingPol>
