Usage Guidelines
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).
Examples 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)#
