Configuring a Layer 3 aggregation group
Configuring a Layer 3 static aggregation group
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Create a Layer 3 aggregate interface and enter Layer 3 aggregate interface view. | interface route-aggregation interface-number | When you create a Layer 3 aggregate interface, the system automatically creates a Layer 3 static aggregation group with the same number as that aggregate interface. |
3. Exit to system view. | quit | N/A |
4. Assign an interface or subinterface to the specified Layer 3 aggregation group. | Enter Layer 3 Ethernet interface or subinterface view:interface { interface-number | interface-number.subnumber } Assign the interface or subinterface to the specified Layer 3 aggregation group:port link-aggregation group group-id | You can assign multiple Layer 3 Ethernet interfaces or subinterfaces to an aggregation group. |
Configuring a Layer 3 dynamic aggregation group
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Set the system LACP priority. | lacp system-priority priority | By default, the system LACP priority is 32768. Changing the system LACP priority might affect the aggregation states of the ports in the dynamic aggregation group. |
3. Create a Layer 3 aggregate interface and enter Layer 3 aggregate interface view. | interface route-aggregation interface-number | When you create a Layer 3 aggregate interface, the system automatically creates a Layer 3 static aggregation group with the same number as that aggregate interface. |
4. Configure the aggregation group to operate in dynamic mode. | link-aggregation mode dynamic | By default, an aggregation group operates in static mode. |
5. Exit to system view. | quit | N/A |
6. Assign an interface or subinterface to the specified Layer 3 aggregation group. | Enter Layer 3 Ethernet interface or subinterface view:interface { interface-number | interface-number.subnumber } Assign the interface or subinterface to the specified Layer 3 aggregation group:port link-aggregation group group-id | You can assign multiple Layer 3 Ethernet interfaces or subinterfaces to an aggregation group. |
7. Set the LACP operating mode on the interface. |
| By default, LACP is operating in active mode. |
8. Set the port priority of the interface. | link-aggregation port-priority priority | The default setting is 32768. |
9. (Optional.) Enable the short LACP timeout interval (3 seconds) on the interface. | lacp period short | By default, the long LACP timeout interval (90 seconds) is used on the interface. To avoid traffic interruption during an ISSU, do not enable the short LACP timeout interval before performing the ISSU. For more information about ISSU, see Fundamentals Configuration Guide. |
