Bundling Ports with EtherChannel
Fast EtherChannel is accessible on the Catalyst 1900, 2820, 2900, 2900XL, 3500XL, 4000,
5000, and 6000 families. Gigabit EtherChannel is accurate alone on the Catalyst 2900,
2900XL, 4000, 5000, and 6000 families. Most of the about-face families abutment a best of
four FE or GE links arranged in a distinct EtherChannel link. However, the Catalyst 6000 family
supports up to eight arranged links for a absolute throughput of 1600 Mbps (FEC) or 16 Gbps
(GEC). The Catalyst 6000 additionally supports up to 128 alone EtherChannel links.
On the majority of Catalyst about-face modules, EtherChannel bundles accept several configuration
restrictions. For example, either two or four ports charge be arranged and these ports charge be

contiguous on the about-face module. Newer about-face modules acquiesce the ports to be called from
anywhere on the bore or alike beyond modules. Generally, all arranged ports charge aboriginal belong
to the aforementioned VLAN. If acclimated as a trunk, arranged ports charge all be in trunking approach and canyon the
