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

NameTypeDescription
tapDevicestringThe name of the TAP device
redirstringUser mode redirection of host port to virtual port (using SLiRP), command format <protocol>:<host port>:<ip address>:<virtual port>
tftpPrefixstringPath to the root of the tftp directory. To use tftp, fetch from the host (gw) IP address.
macaddressuns64The MAC address (hex number)
macprefixuns32The first two bytes of MAC addresses (hex number) on the VLAN
