EtherChannel Feature Overview

An EtherChannel bundles individual Ethernet links into a single logical link that provides the aggregate
bandwidth of up to eight physical links. The maximumnumber of EtherChannels is 128.
You can form an EtherChannel with up to eight compatibly configured LAN ports on any module in a
Catalyst 6500 series switch. All LAN ports in each EtherChannel must be the same speed and must all
be configured as either Layer 2 or Layer 3 LAN ports.
