Link Aggregation Commands
Ports can be statically grouped into an aggregate link (i.e., trunk) 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. For
static trunks, the switches have to comply with the Cisco EtherChannel
standard. For dynamic trunks, the switches have to comply with LACP. This
switch supports up to six trunks. For example, a trunk consisting of two
1000 Mbps ports can support an aggregate bandwidth of 4 Gbps when
operating at full duplex.
