The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

To use hardware hashing for multicast traffic on an EtherChannel interface, use the hardware multicast hw-hash command. To restore the defaults, use the no form of this command.
hardware multicast hw-hash
no hardware multicast hw-hash
This command has no arguments or keywords.
The software selection method is used for multicast traffic.

By default, ingress multicast traffic on any port in the switch selects a particular EtherChannel member to egress the traffic. To reduce potential issues with the bandwidth and to provide effective load balancing of the ingress multicast traffic, hardware hashing is used for multicast traffic.
![]() Note | Hardware hashing is not available on a Cisco Nexus 2000 Series Fabric Extender HIF port (downlink port). |
This example shows how to set the hardware hashing for multicast traffic on an EtherChannel interface:
switch(config)# interface port-channel 21 switch(config-if)# hardware multicast hw-hash switch(config-if)#
This example shows how to restore the default software selection method for multicast traffic on an EtherChannel interface:
switch(config)# interface port-channel 21 switch(config-if)# hardware multicast hw-hash switch(config-if)# no hardware multicast hw-hash switch(config-if)#
