This command provides the configuration to select source Boxer Internal Address (SBIA) as the input to the hashing
function for ECMP-LAG distribution.

Syntax
[no] ecmp-lag hash use-sbia-only
no
Disables the hashing function selection and sets the system to use IP Source Address, IP Destination Address,
IP Protocol and Source BIA as inputs to the hashing algorithm for ECMP-LAG distribution.
IP Protocol and Source BIA as inputs to the hashing algorithm for ECMP-LAG distribution.
Usage
Use this command to allow the operator to change the way hashing works in deciding which link to use for
ECMP and Link Aggregation. In the default hashing algorithm the IP Source Address, IP Destination
Address, IP Protocol and Source BIA are used in the hashing function. When “use-sbia-only” option is
selected, only the Source BIA is used in the hashing function.

Caution:
When using ECMP-LAG on a HNB-GW, this configuration is mandatory for
standalone HNB-GW deployment and highly recommended in other deployment scenarios where
HNB-GW is used in combination with other services.

Example
The following command enables the SBIA as input to hash function for ECMP-LAG on the HNB-GW:
ecmp-lag hash use-sbia-only
The following commands sets the hashing function to use standard inputs for ECMP-LAG on HNB-GW:
no ecmp-lag hash use-sbia-only
