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 26 trunks. For
example, a trunk consisting of two 1000 Mbps ports can support an aggregate
bandwidth of 4 Gbps when operating at full duplex.

lacp port-priority Configures a port's LACP port priority
lacp system-priority Configures a port's LACP system priority
lacp admin-key Configures an port channel's administration key
lacp timeout Configures the timeout to wait for next LACPDU
