7.5 Using Ethernet aggregation on the uplinks of the Ethernet
gateway module
As noted briefly in 7.1, “Introduction to the Ethernet gateway module” on page 118, the
Ethernet gateway module supports the ability to aggregate (also known as EtherChannel or
Trunking) multiple links on the same gateway module, to provide for added bandwidth and
increased high availability.
7.5.1 Some facts about this feature with this gateway module
When using Ethernet aggregation with this gateway module, remember:
򐂰 Up to six ports can be aggregated together. They must be on the same gateway module
(you cannot aggregate between different modules in the same or other chassis).
򐂰 A link aggregation group can be assigned one bridge group or multiple bridge groups.
򐂰 VLAN tagging is supported with this feature.
