G8264 Application Guide for ENOS 8.4
When using LAGs between two switches, as shown in Figure
virtual link between the switches, operating with combined throughput levels that
depends on how many physical ports are included.
Each G8264 supports up to 64 LAGs in stand‐alone (non‐stacking) mode, or 64
LAGs in stacking mode. Two LAG types are available: static LAGs (portchannel),
and dynamic Link Aggregation Control Protocol (LACP) LAGs. Each type can
contain up to 32 member ports, depending on the port type and availability.

LAG
LAGs are also useful for connecting a G8264 to third‐party devices that support
link aggregation, such as Cisco routers and switches with EtherChannel
technology (not ISL aggregation technology) and Sunʹs Quad Fast Ethernet
Adapter. LAG technology is compatible with these devices when they are
configured manually.
LAG traffic is statistically distributed among the ports in a LAG, based on a variety
of configurable options.
Also, since each LAG is comprised of multiple physical links, the LAG is inherently
fault tolerant. As long as one connection between the switches is available, the
trunk remains active and statistical load balancing is maintained whenever a port
in a LAG is lost or returned to service.
