).
For example,
login as: admin
Sent username "admin"
password: password
The configuration wizard automatically starts after you enter the login and default password.
After you have established a connection, you configure the Steelhead appliance using the configuration
wizard:

For in-path configurations, see “Configuring In-Path Steelhead Appliances” on page 31 .

For out-of-path configurations, see “Configuring Out-of-Path Steelhead Appliances” on page 40 .
Configuring In-Path Steelhead Appliances
In a physical in-path deployment, the Steelhead appliance is physically in the direct path between clients
and servers. The clients and servers continue to see client and server IP addresses. Physical in-path
configurations are suitable for any location where the total bandwidth is within the limits of the installed
Steelhead appliance. For a detailed figure, see
“Choosing a Network Deployment” on page 23 .
For detailed information about in-path deployments, see the Steelhead Appliance Deployment Guide .
Avoiding Duplex Mismatch
Before you begin the configuration process, ensure that your LAN and WAN interfaces have the same
duplex settings.
The Steelhead appliance automatically negotiates duplex settings. If one end of the link is set to auto-
negotiate and the other end of the link is not set to auto-negotiate, 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 appliance WAN interface

Steelhead appliance LAN interface

Steelhead appliance primary interface
The following can be signs of a duplex mismatch:

On the Reports > Diagnostics > System Logs page, you see errors for sends, receives, CRC, and short
sends.

You cannot connect to an attached device.

You can connect to a device when you choose auto-negotiation, but you cannot connect to that same
device when you manually set the speed or duplex.

Slow performance across the network.
For detailed information about checking for duplex mismatches, see “Duplex Mismatch” on page 46 .
