Port Trunk Groups
When using port trunk groups between two switches, as shown in Figure 3, you can create a virtual
link between the switches, operating with combined throughput levels that depends on how many
physical ports are included. Each GbE2c supports up to 12 trunk groups, and each trunk group can
contain up to 8 member ports.
Figure 3 Port Trunk Group
Trunk groups are also useful for connecting a GbE2c 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.
The GbE2c detects broken trunk links (link down or disabled) and redirects traffic to other trunk
members within that trunk group. You can only use trunking if each link has the same configuration
for speed, flow control, and auto-negotiation.
