Figure 10. QGLC Link Aggregation Traffic Flow
The aggregator and each MAC share the same MAC address, which means the MAC has no need to parse two different
unicast MAC addresses.

Frame distribution uses an algorithm to distribute frames among MACs that prevents both the mis-ordering of frames
belonging to the same “conversation,” and frame duplication.

XGLC Link Aggregation
Because the XGLC is a full-height card that requires top and bottom card slots, link aggregation takes place horizontally
within ports on different XGLCs.
within ports on different XGLCs.
Link Aggregation Control
One port in an aggregation group is configured as a master so that all traffic (except control traffic) in the aggregation
group logically passes through this port. It is recommended (although not required) that you set up the master first by
managing card/slot/ports, and unset last.

The following command creates link aggregation group N with port slot#/port# as master. Only one master port is
allowed for a group. N must be in the range of [1...1023].
