Chapter 3 Switch Software Features
EtherChannels An EtherChannel (or port group) is a group of two or more Fast Ethernet or
Gigabit Ethernet switch ports bundled into a single logical link, creating a higher
bandwidth link between two switches. The switch supports up to six
EtherChannels. Each EtherChannel can consist of up to eight compatible,
configured ethernet ports.
Figure 10 shows two EtherChannels. Two Full-duplex 10/100/1000-Mbps ports
on Switches A and C create an EtherChannel with a bandwidth of up to 4 Gbps
between both switches. Similarly, two Full-duplex 10/100 ports on Switches B
and D create an EtherChannel with a bandwidth of up to 400 Mbps between
both switches.
If one of the ports in the EtherChannel becomes unavailable, traffic is sent
through the remaining ports within the EtherChannel.
