Chapter 5 – Port Trunking
Trunk groups can provide super-bandwidth, multi-link connections between Alteons or other trunk-
capable devices. A trunk group is a group of ports that act together, combining their bandwidth to
create a single, larger virtual link. This chapter provides configuration background and examples for
trunking multiple ports together either in a static (manually configured) trunk group, or dynamic
trunk group using Link Aggregation Control Protocol (LACP).
The following topics are addressed in this chapter:
• Overview, page 89
• Static Port Trunking, page 91
• Link Aggregation Control Protocol Trunking, page 93

Overview

When using port trunk groups between two Alteons, as shown in
Group Between Alteons, page
gigabits per second, depending on how many physical ports are combined. Alteon supports up to 12
static trunk groups per Alteon, each with two to eight ports per group.

Trunk groups are also useful for connecting an Alteon to third-party devices that support link
aggregation, such as Cisco routers and switches with EtherChannel
technology) and Sun's Quad Fast Ethernet Adapter. Trunk group technology is compatible with these
devices when they are configured manually.
