On the equipment tree, right-click on an NE and choose Properties. The Network Element (Edit) form opens.

Click on the Globals tab. The Load Balancing tab is displayed.

Configure the required load balancing parameters.

To enable system-wide enhanced multicast load balancing to send multicast traffic over a LAG, set the Multicast Enhanced Load Balancing parameter to true.

To improve the LAG spraying of VLL service packets when ECMP and LAG hashing are performed by the same NE, set the Service ID Lag Hashing parameter to true.

For 7250 IXR, Release 19.7 and later, you can specify the CRC polynomials used in ECMP and LAG hashing, by setting the Hash Polynomial values. This is a global setting that affects system-wide ECMP and LAG hashing. The same value cannot be used for both ECMP and LAG. The Hash Polynomial settings use the hash seed result obtained by shifting to optimize the load balancing distribution of packet flows under ECMP and LAG. The number of bits the hash seed result is shifted is specified by the Hash Seed Shift parameter at the card level.

Save your changes and close the form.
