  1. Load network adapter (if required)

    If you are configuring a DEQNA, DESQA, DELQA, DEUNA, DELUA, DEMNA, DEBNI or PMADAA adapter, use the "load" command as shown below. CHARON-VAX 3100/96/98 and 4000/106/108 emulations automatically load SGEC (with the name "EZA") and therefore no "load" command is required.

    Example:

    load DELQA/DEQNA NIC

              

  2. Load "packet_port"

    Load "packet_port" to connect the SGEC, DEQNA, DESQA, DELQA, DEUNA, DELUA, DEMNA, DEBNI or PMADAA adapter to the host hardware network card (or to a virtual network interface).

    Example:

    load packet_port/chnetwrk NDIS interface = "connection:Charon"

               

  3. Connect the loaded "packet_port" to the loaded virtual network adapter

    Connect the SGEC, DEQNA, DESQA, DELQA, DEUNA, DELUA, DEMNA, DEBNI or PMADAA adapter to the "packet_port" by setting the interface name.

    Example

    set NIC interface = NDIS


(warning) Network booting is supported with exception of VAX6xxx models.

Parameter

rx_fifo_size

TypeNumeric
Value

"rx_fifo_size" sets the receive FIFO size.

The value is specified in Kb and, by default, is pre-calculated from the connected port’s size of the receive queue.

Typically, you do not need to change the "rx_fifo_size" parameter. It is available for extended tuning and debugging purposes.

...


Example:

load packet_port/chnetwrk EZA0 interface = "connection:Charon"

set EZA interface = EZA0

set EZA station_address="0C:FE:35:AA:67:3B"

Packet Port

The CHARON-specific "packet_port" interface establishes a connection between an Ethernet adapter in the Windows host system and a network adapter in the virtual VAX/PDP11 system.

...

Parameterlegacy_mode
TypeBoolean
Value

If this parameter is set to "true" CHARON-VAX tries to use very first implementation of "packet_port" having certain restrictions such as inability to automatically change MAC address on given interface etc.

This setting may be needed if CHARON-VAX runs in VMware environment for example and you do not want to allow promiscuous mode.

In other situations please do not change its default value ("false").

Example:

set pp_1 legacy_mode=true


Info

This parameter is required only if you do not want to allow promiscuous traffic for the VMware adapter/port. In this mode, CHARON-VAX uses legacy MAC address change logic, so use of this option is not desirable.

Thus for ESXi networking configuration:

  1. Create the port with e1000 adapter;
  2. Enable the promiscuous traffic;
  3. Do not use legacy_mode option in Charon's configuration file

load packet_port/chnetwrk XQA0 interface="connection:Charon"
