All the emulated controllers are loaded and configured in the same way.
The Ethernet adapter in the Linux host system must support dynamic changes of its MAC address (i.e. no reboot of the host system is required to change the MAC address), which is the case with nearly all modern Ethernet adapters.
By default the PCI Ethernet adapters use first available PCI slot. If instead some particular slot is needed, refer to this section for details of specific placement of PCI peripherals on CHARON-AXP PCI bus.
...
Load network adapter (if required)
Use the "load" command as shown below.
Example:For DEC21040 adapters For Intel i8255x adapters load DE500BA/dec21x4x NICload DE602/i8255x NIC By default each loaded virtual network adapter uses first available PCI slot. If instead some particular slot is neded, refer to this section for details of specific placement of PCI peripherals on CHARON-AXP PCI bus.Load "packet_port" or "tap_port"
Load "packet_port" or "tap_port" to connect network adapter to the host hardware network card (or to a virtual network interface).
Example:load packet_port/chnetwrk NDIS interface = "eth1"Connect the loaded "packet_port" ("tap_port") to the loaded virtual network adapter
Connect the network adapter to the "packet_port" ("tap_port") by setting the interface name.
Example:set NIC interface = NDIS

The EIx0_MODE variable name is case insensitive, while its values are case sensitive! This is feature of OpenVMS EIDRIVER.
The values are:
| Parameter | Description |
|---|---|
| "Auto" | Auto-negotiate (default) |
| "Twisted" | 10Mbps half duplex |
| "Full" | 10Mbps full duplex |
| "Fast" | 100Mbps half duplex |
| "FastFD" | 100Mbps full duplex |

| Parameter | port_pending_tx_number | |
|---|---|---|
| Type | Numeric | |
| Value | The "port_pending_tx_number" parameter sets the number of buffers the port uses to transmit. The default value is 62. You may want to increase the "port_pending_tx_number" value if the log file indicates dropped TX packets due to TX queue overflow. Typically, you do not need to change this parameter. Example:

| Parameter | log | |
|---|---|---|
| Type | Text string | |
| Value | If this parameter is set to some valid file name CHARON VM logs Recv and Xmit packets at the emulated port layer. In certain situations enabling this parameter may help to detect loss of packets. Example:
