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.
