Chapter 3 Configure Switch Features
EtherChannels An EtherChannel, or port group, is a group of two or more Fast Ethernet or
Gigabit Ethernet switch ports that are bundled into a logical link. The group
creates a higher bandwidth link between two switches. For example, four
10/100 switch ports can be assigned to an EtherChannel to provide full-duplex
bandwidth of up to 800 Mb/s. If one of the ports in the EtherChannel
becomes unavailable, traffic is carried over the remaining ports within the
EtherChannel.
All ports in an EtherChannel must have the same characteristics:
•
All are applied with the Smartports IE Switch port role and belong to
the same VLAN.
•
All are either 10/100 ports, or all are 10/100/1000 ports. You cannot
group a mix of 10/100 and 10/100/1000 ports in an EtherChannel.
•
All are enabled. A disabled port in an EtherChannel is treated as a link
failure, and its traffic is transferred to one of the remaining ports in the
EtherChannel.
Table 52 shows the maximum number of EtherChannels available per switch.
Each EtherChannel can consist of up to eight compatible, configured Ethernet
ports.
IMPORTANT Do not enable Layer 3 addresses on the physical EtherChannel interfaces.
