Dualport NIC cards

What are the autoexec.ncf commands to enable a secondary NIC port (on a seperate switch) to act as a failover device?

Re: Dualport NIC cards

depends on if you are using NFT.NLM or CPQANS.LAN for the Teaming Driver.
CPQANS.LAN replaces NFT.NLM and is the latest.

Here is example using CPQANS.LAN

EXAMPLE #1 Simple NFT TEAM
==========================
The following is an example of an NFT Team that consists of a Gigabit
adapter and a Compaq Fast Ethernet adapter. The Gigabit adapter is the primary adapter
and the Compaq Fast Ethernet adapter is the secondary. Note that only an
NFT mode Team can combine a Compaq Gigabit adapter and a Compaq Fast
Ethernet adapter. See the NWTEAM.txt file for information about mixing adapters.
For simplicity, only the default frame type 802.2 is used. By default,
CPQANS uses the frame type 802.2. So, you do not need to specify
802.2 on the command line. Also by default, CPQANS uses the
NFT mode. In this example, only one instance of each adapter is present
in the system, so you do not need to specify a slot number.
Also, this example checks the "status" of the Team after each command.

1. Load CPQANS.LAN to form the basis of a Team. For this example,
CPQANS is only loaded once. If multiple frame types are used,
CPQANS is loaded once for each frame type.

LOAD CPQANS FRAME=ETHERNET_802.2

Now, check the status of the Team.

LOAD CPQANS STATUS

2. Load the base driver for each adapter and frame type for the Team. As
this example only uses 802.2, each adapter has its base driver
loaded only once.

LOAD N1000
LOAD N100

3. When you load CPQANS.LAN, it looks like a protocol, so you can
bind it to the physical adapter. Bind CPQANS.LAN to each physical adapter
in the Team. Notice the key word "PRIMARY." For performance
reasons the Compaq Gigabit adapter should be the primary adapter.

BIND CPAQNS N1000 PRIMARY
BIND CPQANS N00

Now, check the status of the Team. Notice that the Team now
has two adapter instances with the Team. Also notice that the Team is
in the "UNCOMMITED" state. The Compaq Gigabit adapter is the "PRIMARY."

LOAD CPQANS STATUS

4. The "COMMIT" command finalizes the Team. Since we have not chosen
the mode of the Team, it is NFT by default.

LOAD CPQANS COMMIT

Now, check the status of the Team. Notice that NFT is now
the Team mode and that the Team is now in the "committed" state.
No changes to the Team can be made once the Team is "committed".

LOAD CPQANS STATUS

5. Now that the Team is in the "commit" state, the CPQANS Team
appears as a virtual adapter. You may now bind a protocol to CPQANS.
Always make sure that your adapters and CPQANS are using the same
frame type!

BIND IPX CPQANS NET=102

Now, check the status of the Team.

LOAD CPQANS STATUS
