BLADEOS 6.5.2 Application Guide

Trunking Overview

When using port trunk groups between two switches, as shown in Figure 7, you can create a virtual link between the switches, operating with combined throughput levels that depends on how many physical ports are included.

Each G8124 supports up to 12 trunk groups. Two trunk types are available: static trunk groups (portchannel), and dynamic LACP trunk groups. Each type can contain up to 8 member ports, depending on the port type and availability.

Trunk groups are also useful for connecting a G8124 to third-party devices that support link aggregation, such as Cisco routers and switches with EtherChannel technology (not ISL trunking technology) and Sun's Quad Fast Ethernet Adapter. Trunk Group technology is compatible with these devices when they are configured manually.

Trunk traffic is statistically distributed among the ports in a trunk group, based on a variety of configurable options.

Also, since each trunk group is comprised of multiple physical links, the trunk group 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 trunk group is lost or returned to service.
