Configuration steps
To configure CHARON-VAX / CHARON-PDP networking, follow these 3 steps:
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.
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".
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
SGEC Ethernet Controller
The built-in SGEC controller emulator ("EZA") has the following parameters that are specified with the "set" command:
interface
...
Text string. Can be either "(disabled)" for a disabled interface or "connection:<Windows network interface name>"
...
.
| Info | |
|---|---|
The interface name can be either " Examples:

Network booting is supported with exception of VAX6xxx models.
SGEC Ethernet Controller
The built-in SGEC controller emulator ("EZA") has the following parameters that are specified with the "set" command:
interface
| Parameter | interface |
|---|---|
| Type | Text string |
| Value | Name of the corresponding instance of the "packet_port" component |
...
| Parameter | station_address | |||
|---|---|---|---|---|
| Type | Text String | |||
| Value | The "station_address" provides the ability to configure the adapter’s permanent address. By default the adapter’s permanent address is read from the host system’s NIC. Set the "station_address" when you need to configure a satellite (remotely booted) system that will run DECnet or when the migrated software uses the permanent address on the network adapter. Format:
or
Example:
|
...
| Parameter | suspend_msg_on_mac_change | |
|---|---|---|
| Type | Boolean | |
| Value | To avoid confusion arising from non critical errors during a MAC address change, logging is by default suppressed (default value is "true"). To enable tracing during a MAC address change set this parameter to "false" Example:
|
log
| Parameter | log | ||||
|---|---|---|---|---|---|
| Type | Text string | ||||
| Value | If this parameter is set to some valid file name or a directory where the log files for each individual session will be stored CHARON VM logs Recv and Xmit packets at the emulated port layer. If an existing directory is specified, CHARON VM automatically enables creation of individual log files, one for each session using the same scheme as used for the generation of the rotating log files. If the "log" parameter is omitted, CHARON VM does not create log. In certain situations enabling this parameter may help to detect loss of packets. Example:
|
legacy_mode
| Parameter | legacy_mode | |||
|---|---|---|---|---|
| Type | Boolean | |||
| 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:
