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 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

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 eight 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, duplex mode and flow control), VLAN
assignments, and CoS settings.
