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

UIDELINES FOR REATING
General Guidelines –
Finish configuring port trunks before you connect the corresponding
◆
network cables between switches to avoid creating a loop.
A trunk can have up to 8 ports.
◆
The ports at both ends of a connection must be configured as trunk
◆
ports.
All ports in a trunk must be configured in an identical manner, including
◆
communication mode (i.e., speed and duplex mode), VLAN
assignments, and CoS settings.
