OVP Peripheral Model: OVPEthernetBridge
Model Specific Information
This page provides introductory usage information for an Imperas OVP peripheral behavioral model.
The page is split into sections providing specific information for this peripheral,
including any ports for connecting into a platform, registers, other component parts, and configuration options and general information for peripheral modeling with Imperas OVP.
Description
Bridges between a packetnet and the host's network
Limitations
None.
Licensing
Open Source Apache 2.0
Reference
This is not based upon the operation of a real device but is used in a virtual platform to connect the internal virtual Ethernet bus to the host network.
Location
The vEthernet_Bridge peripheral model is located in an Imperas/OVP installation at the VLNV: ovpworld.org / peripheral / vEthernet_Bridge / 1.0.
Peripheral Instance Parameters
This model accepts the following parameters:
Table : Peripheral Parameters
Name | Type | Description |
---|
tapDevice | string | The name of the TAP device |
redir | string | User mode redirection of host port to virtual port (using SLiRP), command format <protocol>:<host port>:<ip address>:<virtual port> |
tftpPrefix | string | Path to the root of the tftp directory. To use tftp, fetch from the host (gw) IP address. |
macaddress | uns64 | The MAC address (hex number) |
macprefix | uns32 | The first two bytes of MAC addresses (hex number) on the VLAN |
network | string | The (v4) IP address of the local network device. |
logfile | string | The file to which Ethernet frames should be logged. Uses pcap file format, viewable by Wireshark and other programs. Do not use if this device is connected to a packetnet |
record | string | Record external events into this file |
replay | string | Replay external events from this file |
