If XOR results are 0, the traffic will go via the 1 st port of the LAG and if result will be 1 it will go via the 2nd port of the LAG. That means we need to use only last bit of the address for XOR comparison so we could have 0 or 1.
Since we are using 2 ports for LAG we can have only two different results from XOR, either 0 or 1.

We will compare algorithm mode MAC Address with MAC/IP address. If those remain unchanged, there will not be any difference in the algorithm behavior. It is purely based on header information on the packet. This implies that one client to server connection would not be able to exceed one port throughput no matter how many ports are in a LAG. This means that for specific packets with the same MAC and/or IP addresses, traffic will be sent via one specific port and not two or three at the same time. These switches provide load balance between LAG ports using XOR on MAC address (destination and source) or combination MAC/IP address (destinations and sources).

Please note that Cisco 350 and 550 series switches use the Exclusive OR (XOR) method to choose the interface which is forwarding traffic. How LAG Load Balancing Works on Cisco 350 and 550 Series Switches Additionally, 4 clients connected to one switch, 4 servers connected to the second switch. Two switches connected via LAG using 2 ports only and load balance algorithm MAC Address vs MAC/IP address. Protocols, such as Spanning Tree, consider all the ports in the LAG to be one port.
When the port is removed from the LAG, its original configuration is reapplied. When a port is added to a LAG, the configuration of the LAG is applied to the port.No more than 8 ports are assigned to a static LAG and no more than 16 ports can be candidates for a dynamic LAG.Ports in a LAG must not be assigned to another LAG.All ports in a LAG must be of the same media type, such as Ethernet cable connectivity.All devices support up to 8 ports in a LAG group.Įvery LAG has the following characteristics:
The 550 family of devices support up to 32 LAGs. The 350 family of devices support up to 8 LAGs. In particular, the LAG has port attributes similar to a regular port, such as state and speed. In general, a LAG is treated by the system as a single logical port.
Traffic forwarded to a LAG is load-balanced across the active member ports, thus achieving an effective bandwidth close to the aggregate bandwidth of all the active member ports of the LAG. LAGs increase bandwidth while maintaining redundancy between two devices. Link Aggregation Control Protocol (LACP) is part of the IEEE specification (802.3az) that enables you to bundle several physical ports together to form a single logical channel called a LAG.
