half-duplex. This duplex mismatch passes traffic, but it causes late collisions and results in degraded
optimization. To achieve maximum optimization set the network devices to 100 and full.
Steelhead Appliance Ports
The following table summarizes the ports used to connect the Steelhead appliance to your network.
Bypass Card Interface Naming Conventions
The interface names for the bypass cards are a combination of the slot number and the port pairs
(<slot>_<pair>, <slot>_<pair>). For example, if a four-port bypass card is located in slot 0 of your
appliance, the interface names are: lan0_0, wan0_0, lan0_1, and wan0_1 respectively. Alternatively, if the
bypass card is located in slot 1 of your appliance, the interface names are: lan1_0, wan1_0, lan1_1, and
wan1_1
respectively. The maximum number of pairs is nine, which is three six-port bypass cards.

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.
Primary
(PRI)
The management interface that connects the Steelhead appliance to a LAN switch. This
management interface enables you to connect to the Management Console and the
Steelhead CLI.
Tip
: The Primary and Auxiliary ports cannot share the same network subnet.
Tip
: The Primary and in-path interfaces can share the same subnet.
Tip
: 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 cannot have the Primary and Auxiliary ports on the same subnet.
Tip
: The Auxiliary and in-path interfaces cannot share the same network subnet.
Tip
: You cannot use the Auxiliary port for out-of-path Steelhead appliances.
WAN
Connects the WAN port of the Steelhead appliance and the WAN router using a cross-
over cable.
LAN
Connects the LAN port of the Steelhead appliance and the LAN switch using a straight-
through cable.
Note
: If the Steelhead appliance is deployed between two switches, both the LAN and
WAN ports must be connected with straight-through cables.
