SteelHead ports
This table summarizes the ports used to connect the SteelHead to your network.
Avoiding duplex mismatch
Before you begin the configuration process, ensure that your LAN and WAN interfaces have the same
duplex settings.
The SteelHead automatically negotiates duplex settings. If one end of the link is set to autonegotiate and
the other end of the link is not set to autonegotiate, the duplex settings on the network device default
to half-duplex. This duplex mismatch passes traffic, but it causes late collisions and results in degraded
optimization. To achieve maximum optimization, set your network devices to 100 and
full .
To avoid duplex mismatches, manually configure the duplex settings on your:
• router
• switch
• SteelHead WAN interface
• SteelHead LAN interface
Port Description
Console Connects the serial cable to a terminal device. You establish a serial connection to a
terminal emulation program for console access to the configuration wizard and the
SteelHead CLI.
Depending on your appliance, the Console port is either a DB9M port or an RJ45 port.
(For port details for your appliance model, see the specification appendix for your
product.)
The appropriate console cable ships with your appliance.
Primary
(PRI) The management interface that connects the SteelHead to a LAN switch. This
management interface enables you to connect to the Management Console and the
SteelHead CLI.
The primary and auxiliary ports can’t share the same network subnet.
The primary and in-path interfaces can share the same subnet.
You must use the primary port on the server-side for out-of-path deployments.
Auxiliary (AUX) An optional port that provides an additional management interface for a secondary
network. You can’t have the primary and auxiliary ports on the same subnet.
The auxiliary and in-path interfaces can’t share the same network subnet.
You can’t use the auxiliary port for out-of-path SteelHeads.
This port is not available on the SteelHead model CX 255.
WAN Connects the WAN port of the SteelHead and the WAN router using a crossover cable.
LAN Connects the LAN port of the SteelHead and the LAN switch using a straight-through
cable.
Note : If the SteelHead is deployed between two switches, both the LAN and WAN ports
must be connected with straight-through cables.
