Which of the following statements describe how LACP determines whether an interface is an active interface or a standby interface?
A. |
Ports with higher LACP port priorities are preferred over ports with lower LACP port priorities. | |
B. |
Ports with lower LACP port priorities are preferred over ports with higher LACP port priorities. | |
C. |
When LACP port priorities are equal, ports with higher port numbers are preferred over ports with lowerport numbers. | |
D. |
When LACP port priorities are equal, ports with lower port numbers are preferred over ports with higherport numbers. | |
E. |
When LACP port priorities are equal, all ports with equal priorities are configured as active interfaces. |
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.
