Chapter 28 Link Aggregation Commands - Supermicro SSE-G2252 User Manual

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.
