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), also known as
802.1ad, to automatically negotiate a trunk link between this switch and
another network device. For static trunks, the switches have to be
compatible 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.

Guidelines for Creating Trunks

• Finish configuring port trunks before you connect the corresponding

network cables between switches to avoid creating a loop.

• A trunk can contain up to four 10/100 Mbps ports or up to two 1000

Mbps ports.

• The ports at both ends of a connection must be configured as trunk

ports.

• All ports in a trunk must consist of the same media type (i.e.,

twisted-pair or fiber).
