Info

The interface name can be either "(disabled)" for a disabled interface or "connection:<Windows network interface name>"

Examples:

load packet_port/chnetwrk NIC1 interface="(disabled)" load packet_port/chnetwrk NIC2 interface="connection:CHARON_NIC"

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	Text string
Value	Name of the corresponding instance of the "packet_port" component

...

Div

class	pagebreak

station_address

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:

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 the receive queue.

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

DEQNA, DESQA, DELQA, DEUNA and DELUA offer the following configuration parameters that can be specified using the "set" command:

address

Parameter address

Type

Numeric

Value

Specifies the CSR address. The address must be a valid QBUS and UNIBUS address in I/O space. Initial value is 017774440, which is the factory setting for DEQNA, DESQA and DELQA Ethernet controllers.

Use the address parameter if loading several instances of DEQNA, DESQA, DELQA, DEUNA and DELUA Ethernet controllers.

"address" parameter values must be unique for every instance of an DEQNA, DESQA, DELQA, DEUNA and DELUA Ethernet controller.

Example:

load DEQNA/DEQNA XQA address=017774440 load DEQNA/DEQNA XQB address=017764460

"packet_port" uses several configuration parameters to control its behavior.

interface

Parameter interface

Type

Text string

Value

This parameter identifies an Ethernet adapter of the host system dedicated to CHARON-VAX / CHARON-PDP with a keyword "connection" preceeding it.

Syntax:

set <name> interface="connection:<adapter>"

Example:

set pp_1 interface="connection:Charon"

Div

class	pagebreak

port_enable_mac_addr_change

Parameter

port_enable_mac_addr_change

Type Boolean

Value

If "true" is specified (default value), CHARON sets the appropriate Ethernet address automatically.

If "false" is specified, set the Ethernet address manually.

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 a port will attempt to transmit a packet before giving up.

By default, the value is 3.

Increasing this value may introduce problems in carrier loss logic, because not all NIC drivers support a 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

The "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

Div

class	pagebreak

port_pending_tx_number

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:

set pp_1 port_pending_tx_number=128

suspend_msg_on_mac_change

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:

set pp_1 suspend_msg_on_mac_change=false

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 1:

set pp_1 log="pp_1.log"

Example 2:

set pp_1 log="C:\Charon\Logs"

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

...

Div

class	pagebreak

log_flush_period

Parameter log_flush_period

Type Numeric

Value

<period-in-seconds>

Defines a period of flushing log to disk.

Default period is 60 seconds (it means that every minute log file is flushed to disk)

Examples:

set pp_1 log_flush_period=30

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:

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:

Create the port;
Enable the promiscuous traffic;
Do not use legacy_mode option in Charon's configuration file

...

Div

class	commandline

load DEQNA/DEQNA XQAload packet_port/chnetwrk XQA0 interface="connection:Charon"set XQA interface=XQA0

Info
CHARON supports VLAN adapters. If for some reasons you are going to use them, proceed with their installation and configuration according to the network adapter's vendor's User's Guide and then use the resulting VLAN interface the same way as the regular network interface.
