LAG Load Sharing

Brocade devices load share across the ports in the LAG group. The method used for the load sharing depends on the device type and traffic type (Layer 2 or Layer 3).

Support for IPv6 when sharing traffic across a LAG group

Brocade devices that support IPv6 take the IPv6 address for a packet into account when sharing traffic across a LAG group. The load sharing is performed in the same way it is for IPv4 addresses; that is, LAG types with a traffic load that is shared based on IPv4 address information can use IPv6 addresses to determine load sharing.

Load balancing for unknown unicast, multicast, and broadcast traffic

Known unicast traffic is always load balanced across all the ports of a LAG group based on the traffic's Layer 2 and Layer 3 source and destination parameters.

Unknown unicast, multicast, and broadcast traffic is load balanced based either on source and destination IP addresses and protocol field, or, in some cases, on source and destination IP addresses, protocol field, source MAC address, and destination MAC address.

The load balancing method for bridged traffic varies depending on the traffic type. Load balancing for routed traffic is always based on the source and destination IP addresses and protocol field.
