Use the ' ' to identify the netmap interface to be deleted. Implementation: netmap_create_command_fn.ĭelete netmap Summary/usage delete netmap name |valeXXX:YYY.ĭelete a netmap interface. Once the netmap interface is created, enable the interface using: vpp# set interface state netmap-vale00:vpp1 up Declaration and implementationĭeclaration: netmap_create_command ( src/vnet/devices/netmap/cli.c line 152) Defaults to ' slave' if not entered.Įxample usage Example of how to create a netmap interface tied to the linux namespace ' vpp1': vpp# create netmap name vale00:vpp1 hw-addr 02:FE:3F:34:15:9B pipe master master | slave - Optional flag to indicate whether VPP should be the master or slave of the ' netmap pipe'.pipe - Optional flag to indicate that a ' netmap pipe' instance should be created.hw-addr - Optional ethernet address, can be in either X:X:X:X:X:X unix or X.X.X cisco format.This command has the following optional parameters: Where ' YYY' is an existing linux namespace.Where ' valeXXX' is an arbitrary name for a VALE interface that must start with ' vale' and is less than 16 characters.Once created, a new netmap interface will exist in VPP with the name ' netmap-', where ' ' takes one of two forms: - VPP development package for Netmap/VALE, which is a snapshot of the Netmap/VALE repo with minor changes to work with containers and modified kernel drivers to work with NICs.Ĭreate a netmap interface that will attach to a linux interface.Netmap/VALE generates the ' netmap.ko' kernel module that needs to be loaded before netmap interfaces can be created. Together, they provide a high speed user-space interface that allows VPP to patch into a linux namespace, a linux container, or a physical NIC without the use of DPDK. ' netmap' includes ' netmap pipes', a shared memory packet transport channel. ' VALE' is an equally fast in-kernel software switch using the netmap API. ' netmap' is a framework for very fast packet I/O from userspace. Create netmap Summary/usage create netmap name |valeXXX:YYY.
