Configuring LAG LAG Configuration ■■ Configuring LACP Follow these steps to configure LACP: Step 1 configure Enter global configuration mode. Step 2 lacp system-priority pri Specify the system priority for the switch. To keep active ports consistent at both ends, you can set the priority of one device to be higher than that of the other device. The device with higher priority will determine its active ports, and the other device can select its active ports according to the selection result of the device with higher priority. If the two ends have the same system priority value, the end with a smaller MAC address has the higher priority. pri: System priority. The valid values are from 0 to 65535, and the default value is 32768. A smaller value means a higher device priority. Step 3 interface {fastEthernet port | range fastEthernet port-list | gigabitEthernet port | range gigabitEthernet port-list | ten-gigabitEthernet port | range ten-gigabitEthernet port-list ] Enter interface configuration mode. Step 4 channel-group num mode { active | passive } Add the port to an LAG and set the mode as LACP. num: The group ID of the LAG. mode: LAG mode. Here you need to select LACP mode: active or passive. In LACP, the switch uses LACPDU (Link Aggregation Control Protocol Data Unit) to negotiate the parameters with the peer end. In this way, the two ends select active ports and form the aggregation link. The LACP mode determines whether the port will take the initiative to send the LACPDU. passive: The port will not send LACPDU before receiving the LACPDU from the peer end. active: The port will take the initiative to send LACPDU. Step 5 lacp port-priority pri Specify the Port Priority. The port with higher priority in an LAG will be selected as the working port. If two ports have the same priority value, the port with a smaller port number has the higher priority. pri: Port priority. The valid values are from 0 to 65535, and the default value is 32768. A smaller value means a higher port priority. Step 6 show lacp sys-id Verify the global system priority. Step 7 show lacp internal Verify the LACP configuration of the local switch. Step 8 end Return to privileged EXEC mode. User Guide 120
