VALE(4) BSD Kernel Interfaces Manual VALE(4)
NAME
vale -- a very fast Virtual Local Ethernet using the netmap API
SYNOPSIS
device netmap
DESCRIPTION
vale is a feature of the netmap(4) module that implements multiple Virtual switches that can be used to interconnect netmap clients, includ-
ing traffic sources and sinks, packet forwarders, userspace firewalls, and so on.
vale is implemented completely in software, and is extremely fast. On a modern machine it can move almost 20 Million packets per second
(Mpps) per core with small frames, and about 70 Gbit/s with 1500 byte frames.
OPERATION
vale dynamically creates switches and ports as clients connect to it using the netmap(4) API.
vale ports are named vale[bdg:][port] where vale is the prefix indicating a VALE switch rather than a standard interface, bdg indicates a
specific switch (the colon is a separator), and port indicates a port within the switch. Bridge and port names are arbitrary strings, the
only constraint being that the full name must fit within 16 characters.
See netmap(4) for details on the API.
LIMITS
vale currently supports up to 4 switches, 16 ports per switch, with 1024 buffers per port. These hard limits will be changed to sysctl vari-
ables in future releases.
SYSCTL VARIABLES
vale uses the following sysctl variables to control operation:
dev.netmap.bridge The maximum number of packets processed internally in each iteration. Defaults to 1024, use lower values to trade
latency with throughput.
dev.netmap.verbose Set to non-zero values to enable in-kernel diagnostics.
EXAMPLES
Create one switch, with a traffic generator connected to one port, and a netmap-enabled tcpdump instance on another port:
tcpdump -ni vale-a:1 &
pkt-gen -i vale-a:0 -f tx &
Create two switches, each connected to two qemu machines on different ports.
qemu -net nic -net netmap,ifname=vale-1:a ... &
qemu -net nic -net netmap,ifname=vale-1:b ... &
qemu -net nic -net netmap,ifname=vale-2:c ... &
qemu -net nic -net netmap,ifname=vale-2:d ... &
