Network Transmit Enable
This mode controls the state of the transmit path:
The default state is disabled.
The NC filters pass-through packets according to their source MAC address. The NC
tries to match that source MAC address to one of the MAC addresses configured by the
Set MAC Address command. As a result, the MC should enable network transmit only
after configuring the MAC address.
It is recommended that the MC complete all filtering configuration (especially MAC
addresses) before enabling the network transmit.
This feature can be used for fail-over scenarios. See
Asynchronous Event Notifications
The asynchronous event notifications are unsolicited messages sent from the NC to the
MC to report status changes (such as link change, operating system state change,
etc.).
Recommendations:
Querying Active Parameters
The MC can use the Get Parameters command to query the current status of the
operational parameters.
1. Disabled - the channel does not pass any traffic from the MC to the network.
2. Enabled - the channel passes any traffic from the MC (that matched the source

rather after an out-of-context AEN).
