Selecting a reference port
The system selects a reference port from the member ports that are in the up state and have the same
class-two configurations as the aggregate interface.
The candidate ports are sorted by aggregation priority, duplex, and speed in the following order:
• Lowest aggregation priority value
• Full duplex/high speed
• Full duplex/low speed
• Half duplex/high speed
• Half duplex/low speed
The one at the top is selected as the reference port. If two ports have the same aggregation priority,
duplex mode, and speed, the one with the lower port number wins out.
Setting the aggregation state of each member port
After selecting the reference port, the static aggregation group sets the aggregation state of each
member port, as shown in Figure 61.
