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.
