Syntax
system-priority priority;
Hierarchy Level
[edit chassis aggregated-devices ethernet lacp]
Description
Define LACP system priority for aggregated Ethernet interfaces at the global (chassis) level.
The device with the lower system priority value determines which links between LACP partner devices are active and which are in standby for each LACP group. The device on the controlling end of the link uses port priorities to determine which ports are bundled into the aggregated bundle and which ports are put in standby mode. Port priorities on the other device (the noncontrolling end of the link) are ignored. In priority comparisons, numerically lower values have higher priority. Therefore, the system with the numerically lower value (higher priority value) for LACP system priority becomes the controlling system. If both devices have the same LACP system priority (for example, they are both configured with the default setting of 127), the device MAC address determines which switch is in control.
Options
priority—Priority for the aggregated Ethernet system. A smaller value indicates a higher priority.
