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 12 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 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.
