Configuring LAG LAG Configuration 2 LAG Configuration To complete LAG configuration, follow these steps: 1) Configure the global load-balancing algorithm. 2) Configure Static LAG or LACP. Configuration Guidelines  Ensure that both ends of the aggregation link work in the same LAG mode. For example, if the local end works in LACP mode, the peer end should be set as LACP mode.  Ensure that devices on both ends of the aggregation link use the same number of physical ports with the same speed, duplex, jumbo and flow control mode.  A port cannot be added to more than one LAG at the same time.  LACP does not support half-duplex links.  One static LAG supports up to eight member ports. All the member ports share the traffic evenly. If an active link fails, the other active links share the traffic evenly.  One LACP LAG supports more than eight member ports, but at most eight of them can be active. Using LACP protocol, the switches negotiate parameters and determine the active ports. When an active link fails, the link with the highest priority among the inactive links will replace the faulty link and start to forward data.  For the functions like IGMP Snooping, 802.1Q VLAN, MAC VLAN, Protocol VLAN, VLANVPN, GVRP, Voice VLAN, STP, QoS, DHCP Snooping and Flow-Control, the member pot of an LAG follows the configuration of the LAG but not its own. The configurations of the port can take effect only after it leaves the LAG.  The port which is enabled with Port Security, Port Mirror, MAC Address Filtering or 802.1X cannot be added to LAG, and the member port of an LAG cannot be enabled with these functions.
