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.
Example
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.
