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

...

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"

...

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.

Example:

Div

class	commandline

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

set EZA interface = EZA0

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

load packet_port/chnetwrk <instance-name>

Example:

load packet_port/chnetwrk pp_1

...

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"

...

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

...

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

...

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

...

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

...

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

...

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

Example:

set pp_1 legacy_mode=true

Example:

Div

class	commandline

load DEQNA/DEQNA XQA

load 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.

...

During DECnet OSI installation or DECnet OSI interface reconfiguration, DEQNA and DESQA models are not recognized as valid devices. (DECnet OSI SPD).

Info

The integrated SGEC Ethernet "EZA" on a MicroVAX 3100 & VAX 4000-106/108 is supported by DECnet OSI.

The integrated ESA (AMD Lance 7990) device is not currently implemented in CHARON-VAX.
