Host Interface

create host-interface

Summary/usage

create host-interface name <ifname> [hw-addr <mac-addr>].

Description

Create a host interface that will attach to a linux AF_PACKET interface, one side of a veth pair. The veth pair must already exist. Once created, a new host interface will exist in VPP with the name 'host-<ifname>', where '<ifname>' is the name of the specified veth pair. Use the 'show interface' command to display host interface details.

This command has the following optional parameters:

• hw-addr <mac-addr> - Optional ethernet address, can be in either X:X:X:X:X:X unix or X.X.X cisco format.

Example usage

Example of how to create a host interface tied to one side of an existing linux veth pair named vpp1:

vpp# create host-interface name vpp1

host-vpp1

Once the host interface is created, enable the interface using:

vpp# set interface state host-vpp1 up
