Dynamic link aggregation

NOTE
It is recommended to configure a unique key if ports are tagged or untagged in a VLAN.
FIGURE 79 Ports with the same key in different aggregate links
Notice that the keys between one device and another do not need to match. The only requirement
for key matching is that all the ports within an aggregate link on a given device must have the same
key.
Devices that support multi-slot trunk groups can form multi-slot aggregate links using link
aggregation. However, the link aggregation keys for the groups of ports on each module must
match. For example, if you want to allow link aggregation to form an aggregate link containing ports
1 – 4 and 5 – 8, you must change the link aggregation key on one or both groups of ports so that
the key is the same on all eight ports. Figure 80 on page 333 shows an example.
All these ports have
the same key, but are
in two separate
aggregate links with
two other devices.
