Accepted Answer

Ports with higher LACP port priorities are preferred over ports with lower LACP port priorities.

Accepted Answer

When LACP port priorities are equal, ports with lower port numbers are preferred over ports with higherport numbers.

Accepted Answer

The following statements describe how Link Aggregation Control Protocol (LACP) determines whether an interface is an active interface or a standby interface:
- Ports with higher LACP port priorities are preferred over ports with lower LACP port priorities.
- When LACP port priorities are equal, ports with lower port numbers are preferred over ports with higher port numbers.

The lacp port-priority value command configures an LACP interface with a port priority, which is used to determine which interfaces are active interfaces and which interfaces are standby interfaces. The value parameter is a value from 1 through 65535; if no priority value is defined, the default port priority value of 32768 is used.

Setting the LACP port priority to a value of 1 will ensure that the port becomes an active port unless a port with a lower port number is also set to a priority of 1.
