Command Usage

•For Fast Ethernet interfaces, the rate limit granularity is 512 Kbps, 1 Mbps, or 3.3 Mbps.

•For Gigabit Ethernet interfaces, the rate limit granularity is 33.3 Mbps.

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 four trunks. For example, a trunk consisting of two 1000 Mbps ports can support an aggregate bandwidth of

4 Gbps when operating at full duplex.
