The built-in SGEC controller emulator ("EZA") has the following parameters that are specified with the "set" command:
interface
| Parameter | interface |
|---|---|
| Type |
Value
Text String | |
| Value | Name of the corresponding instance of the "packet_port" component |
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:
or
Example: |
|
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 | address | Numeric | 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.

"packet_port" uses several configuration parameters to control its behavior.
interface
| Parameter | interface | ||||
|---|---|---|---|---|---|
| Type | Text string | ||||
| Value | interface | Text string | This parameter identifies an Ethernet adapter of the host system dedicated to CHARON-VAX / CHARON-PDP with a keyword "connection" preceeding it. Syntax:
Example:
|
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:
|
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:
|
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:
|
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:
|
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:
|
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. In other situations please do not change its default value ("false"). Example:
