If set to smac(1), when packets are forwarded to a TrunkGroup, they are distributed across the ports in the TrunkGroup based on the source-MAC address of the incoming packet. Therefore, to provide load balancing, packets from different hosts use different ports in the TrunkGroup, but packets from the same host use the same port in the TrunkGroup. If set to dmac(2),when packets are forwarded to a TrunkGroup, they are distributed across the ports in the TrunkGroup based on the destination host��s MAC address of the incoming packet. Therefore, packets to the same destination are forwarded over the same port, and packets to a different destination are sent on a different port in the TrunkGroup. If set to sdmac(3),when packets are forwarded to an TrunkGroup, they are distributed across the ports in the TrunkGroup based on both the source and destination MAC addresses. This forwarding method, a combination source-MAC and destination-MAC address forwarding methods of load distribution, can be used if it is not clear whether source-MAC or destination-MAC address forwarding is better suited on a particular switch. With source-and-destination MAC-address forwarding, packets sent from host A to host B, host A to host C, and host C to host B could all use different ports in the TrunkGroup. If set to sip(4),when packets are forwarded to a TrunkGroup, they are distributed across the ports in the TrunkGroup based on the source-IP address of the incoming packet. Therefore, to provide load-balancing, packets from different IP addresses use different ports in the TrunkGroup, but packets from the same IP address use the same port in the TrunkGroup. If set to dip(5),when packets are forwarded to a TrunkGroup, they are distributed across the ports in the TrunkGroup based on the destination-IP address of the incoming packet. Therefore, to provide load-balancing, packets from the same IP source address sent to different IP destination addresses could be sent on different ports in the TrunkGroup. But packets sent from different source IP addresses to the same destination IP address are always sent on the same port in the TrunkGroup. If set to sdip(6), packets are sent to a TrunkGroup and distributed across the TrunkGroup ports, based on both the source and destination IP addresses of the incoming packet. This forwarding method, a combination of source-IP and destination-IP address-based forwarding, can be used if it is not clear whether source-IP or destination-IP address-based forwarding is better suited on a particular switch. In this method, packets sent from the IP address A to IP address B, from IP address A to IP address C, and from IP address C to IP address B could all use different ports in the TrunkGroup. If set to disable(7),the TrunkGroup LoadBalance will not work. This object default value is sdip(6).
