19.Port Trunking Commands
Ports can be statically grouped into an aggregate link to increase the bandwidth
of a network connection or to ensure fault recovery. Or you can use the Link
Aggregation Control Protocol (LACP) to automatically negotiate a trunk link
between this switch and another network device. You can configure trunks
between switches of the same type. This switch supports up to six trunks. For
example, a trunk consisting of two 1000Mbps ports can support an aggregate
bandwidth of 4 Gbps when operating at full duplex.
