11 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 27/16 trunks on the
AOS5700-54X and AOS6700-32X respectively. For example, a trunk consisting of
two 1000 Mbps ports can support an aggregate bandwidth of 4 Gbps when
operating at full duplex.
