Understanding the EtherChannel
The EtherChannel is composed of individual Fast Ethernet or Gigabit Ethernet links bundled into a
single logical link as shown in Figure 10-1. The EtherChannel provides full-duplex bandwidth up to
800 Mbps (Fast EtherChannel) or 2 Gbps (Gigabit EtherChannel) between your switch and another
switch or host.
Each EtherChannel can consist of up to eight compatibly configured Ethernet interfaces. All interfaces
in each EtherChannel must be the same speed, and all must be configured as Layer 2 interfaces.
Note The network device to which your switch is connected can impose its own limits on the number of
interfaces in the EtherChannel. For Catalyst 2950 switches, the number of EtherChannels is limited to
six with eight ports per EtherChannel.
If a link within an EtherChannel fails, traffic previously carried over that failed link changes to the
remaining links within the EtherChannel. A trap is sent for a failure, identifying the switch, the
EtherChannel, and the failed link. Inbound broadcast and multicast packets on one link in an
EtherChannel are blocked from returning on any other link of the EtherChannel.
