Ports and trunking
Introduction
The first part of this chapter describes the different types of ports used on the 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 10Gb Ethernet BL-c 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 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 switch provides trunking support for the four external
ports and 16 server ports.
Ports on the switch
The following table describes the Ethernet ports of the 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 10Gb Ethernet BL-c Switch User Guide.
