LAG formation rules

• Make sure the device on the other end of the LAG link can support the same number of ports
in the link.
Figure 3 displays an example of a valid, Keep ALIVE LAG link between two devices. This
configuration does not aggregate ports but uses the LACP PDUs to maintain the connection status
between the two ports.
FIGURE 3 Example of a 1-port keep alive LAG
Figure 4 shows an example of a valid 2-port LAG link between devices where the ports on each end
are on the same interface module. Ports in a valid 2-port LAG on one device are connected to two
ports in a valid 2-port LAG on another device.
FIGURE 4 Example of 2-port LAG
Figure 5 shows an example of two devices connected over a 4 port LAG where the ports on each
end of the LAG are on different interface modules.
