The EIx0_MODE variable name is case insensitive, while its values are case sensitive! This is feature of OpenVMS EIDRIVER.
The values are:
| Parameter | Description |
|---|---|
| "Auto" | Auto-negotiate (default) |
| "Twisted" | 10Mbps half duplex |
| "Full" | 10Mbps full duplex |
| "Fast" | 100Mbps half duplex |
| "FastFD" | 100Mbps full duplex |

load packet_port/chnetwrk pp_1NDIS |
"packet_port" uses several configuration parameters to control its behavior.
Parameter | Type | Value | ||
interface | Text string | This parameter identifies an Ethernet adapter of the host system dedicated to CHARON-AXP with a keyword "connection" preceeding it. Syntax:
Example:
| ||
port_enable_mac_addr_change | Boolean | If "true" is specified (default value), CHARON-AXP sets the appropriate Ethernet address automatically. If "false" is specified, set the Ethernet address manually. Example:
| ||
port_ignore_on_rx | Numeric | The "port_ignore_on_rx" parameter provides the ability to shutdown the port when a specified number of sequential "on receive" errors is exceeded. Typically, errors "on receive" indicate serious (unrecoverable) errors. By default, the value is set to the value of the "port_pending_rx_number" parameter. A value of ‘0’ means infinite. Example:
| ||
port_retry_on_tx | Numeric | 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 | Numeric | 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_rx_number | Numeric | 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 | Boolean | 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:
|

| Info |
|---|
CHARON-AXP 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. |
Supported Ethernet Q-bus Adapters for DECnet OSI (DECnet Plus)
The only supported Q-bus device is the DELQA adapter model.
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. |
Ethernet Q-bus Adapter and Cluster configuration rules
In a VMS Cluster using VMS version 5.5 and above, use only DELQA and DESQA Ethernet adapters that are supported (VMS Cluster SPD).
