Trunk group overview

The Trunk group feature allows you to manually configure multiple high-speed load-sharing links
between two Layer 2 Switches or Layer 3 Switches or between a Layer 2 Switch and Layer 3 Switch
and a server.
In addition to enabling load sharing of traffic, trunk groups provide redundant, alternate paths for
traffic if any of the segments fail.

NOTE
You can use both types of trunking on the same device. However, you can use only one type of
trunking for a given port. For example, you can configure port 1/1 as a member of a static trunk
group or you can enable 802.3ad link aggregation on the port, but you cannot do both.
