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" or "tap_port"
Load "packet_port" or "tap_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 = "eth0"
Connect the loaded "packet_port" ("tap_port") to the loaded virtual network adapter
Connect the SGEC, DEQNA, DESQA, DELQA, DEUNA, DELUA, DEMNA, DEBNI or PMADAA adapter to the "packet_port" ("tap_port") by setting the interface name.

Example:
set NIC interface = NDIS

Network booting is supported with exception of VAX6xxx models.

...

The built-in SGEC controller emulator ("eza") has the following parameters that are specified with the "set" command:

interface

Type
Parameter	interface

Value

interface

Text String
Value	Name of corresponding instance of "packet_port" or "tap_port" component

station_address

Parameter station_address

Type

Text String

Value

"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:

XX-XX-XX-XX-XX-XX

or

XX:XX:XX:XX:XX:XX

Example:

set eza station_address="AF:01:AC:78:1B:CC"

rx_fifo_size

Parameter

rx_fifo_size

Type

Numeric

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 receive queue.

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

To create instances of "packet_port", use the “load” command in the configuration file as follows:

load packet_port/chnetwrk <instance-name>

Example:

load packet_port/chnetwrk pp_1

"packet_port" offers several configuration parameters controlling its behavior.

interface

Type
Parameter	interface

Value

interface

Text string

Value

This parameter Identifies an Ethernet adapter of the host system dedicated to CHARON-VAX.

Syntax:

set <name> interface="<adapter>"

Example:

set pp_1 interface="eth0"

port_enable_mac_addr_change

Boolean

If "true"

Parameter

port_enable_mac_addr_change

Type Boolean

Value

If "true" is specified, CHARON sets the appropriate Ethernet address automatically.

If "false" is specified, set the Ethernet address manually. The default value is "true".

Example:

set pp_1 port_enable_mac_addr_change=false

port_retry_on_tx

Parameter

port_retry_on_tx

Type Numeric

Value

The "port_retry_on_tx" parameter controls the number of times the port will attempt to transmit the packet before giving up.

By default, the value is 3.

Increasing this value may introduce problems in carrier loosing logic because not all NIC drivers support carrier status query.

Typically, you do not need to increase the value.

Example:

set pp_1 port_retry_on_tx=8

port_pending_rx_number

Parameter

port_pending_rx_number

Type

Numeric

Value

"port_pending_rx_number" parameter sets the number of pending receive buffers.

The default value is 63. The maximum value allowed is 195.

You may want to increase the "port_pending_rx_number" when you have very busy networking and experience problems like losing connections not related to the carrier loss.

Typically, you do not need to change this parameter.

Example:

set pp_1 port_pending_rx_number=128

port_pending_tx_number

Parameter

port_pending_tx_number

Type Numeric

Value

"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:

set pp_1 port_pending_tx_number=128

.

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 logs Recv and Xmit packets at the emulated port layer.

If an existing directory is specified, CHARON 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 does not create log.

In certain situations enabling this parameter may help to detect loss of packets.

Example:

set pp_1 log="pp_1.log"

set pp_1 log="/charon/logs"

Note
Only existing directory can be used as a value of the "log" parameter.
