4.2(1)N2(1) |
This command was introduced. |
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)#
