Ports and trunking
Introduction
NOTE: All conceptual diagrams and port mappings in this chapter are based on BL 20p G3 servers. If you are
using a next generation server, then see the latest Quick Setup Instructions card for correct port mappings.
The first part of this chapter describes the different types of ports used on the GbE2 Interconnect Switch. This
information is useful in understanding other applications described in this guide, from the context of the
embedded switch/server environment.
For specific information on how to configure ports for speed, auto-negotiation, and duplex modes, see the port
commands in the HP ProLiant BL p-Class GbE2 Interconnect Switch Command Reference Guide.
The second part of this chapter provides configuration background and examples for trunking multiple ports
together. Trunk groups can provide super-bandwidth, multi-link connections between GbE2 Interconnect Switches
or other trunk-capable devices. A trunk group is a group of links that act together, combining their bandwidth to
create a single, larger virtual link. The GbE2 Interconnect Switch provides trunking support for the six external
ports, two crosslink ports, and 16 server ports.
Ports on the GbE2 Interconnect Switch
The following table describes the Ethernet ports of the GbE2 Interconnect Switch, including the port name and
function.
NOTE: The actual mapping of switch ports to NIC interfaces is dependant on the operating system software,
the type of server blade, and the enclosure type. For more information, see the HP ProLiant BL p-Class GbE2
Interconnect Switch User Guide.
