NOTE:
To identify the port numbers of aggregation member ports, execute the
display
link-aggregation verbose
command and examine the

field in the command output.
Setting the aggregation state of each member port
After the reference port is chosen, the system sets the aggregation state of each member port in the
static aggregation group.
Figure 2 Setting the aggregation state of a member port in a static aggregation group
After the limit on Selected ports is reached, the aggregation state of a new member port varies by
following conditions:
•
The port is placed in Unselected state if the port and the Selected ports have the same port
priority. This mechanism prevents traffic interruption on the existing Selected ports. A device
reboot can cause the device to recalculate the aggregation states of member ports.
•
The port is placed in Selected state when the following conditions are met:
{
The port and the Selected ports have different port priorities, and the port has a higher port
priority than a minimum of one Selected port.
{
The port has the same attribute configurations as the aggregate interface.
Any operational key or attribute configuration change might affect the aggregation states of link
aggregation member ports.
No
Operational key/attribute configurations
same as the reference port?
More candidate ports than max. number of
Selected ports?
Is the port up?
Is there any hardware restriction?
Port number as low as to set the port
to the Selected state?
