#NETMAP SUPPORT HOW TO#

In VPP, netmap interfaces are named as ' netmap-', where ' ' takes one of two forms:Įxample usage Example of how to delete a netmap interface named ' netmap-vale00:vpp1': vpp# delete netmap name vale00:vpp1 Declaration and implementationĭeclaration: netmap_delete_command ( src/vnet/devices/netmap/cli.c line 215) 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: Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime.

- 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. Nmap ('Network Mapper') is a free and open source utility for network discovery and security auditing.Netmap/VALE generates the ' netmap.ko' kernel module that needs to be loaded before netmap interfaces can be created. But my performance result is good, for a simple forwarding configuration, it achieves a 13.

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. Ive got the same problem that after running Click once and killing it for a new settings, it was stuck so I had to reload the NIC driver and netmap module and re-setup the network configuration. ' 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.
