Описание (Description)
The ovs-l3ping
program may be used to check for problems that
could be caused by invalid routing policy, misconfigured firewall
in the tunnel path or a bad NIC driver. On one of the nodes, run
ovs-l3ping
in server mode and on the other node run it in client
mode. The client and server will establish L3 tunnel, over which
client will give further testing instructions. The ovs-l3ping
client will perform UDP and TCP tests. This tool is different
from ovs-test
that it encapsulates XML/RPC control connection
over the tunnel, so there is no need to open special holes in
firewall.
UDP tests can report packet loss and achieved bandwidth for
various datagram sizes. By default target bandwidth for UDP tests
is 1Mbit/s.
TCP tests report only achieved bandwidth, because kernel TCP
stack takes care of flow control and packet loss.
Client Mode
An ovs-l3ping
client will create a L3 tunnel and connect over it
to the ovs-l3ping
server to schedule the tests. TunnelRemoteIP is
the peer's IP address, where tunnel will be terminated. InnerIP
is the address that will be temporarily assigned during testing.
All test traffic originating from this IP address to the
RemoteInnerIP will be tunneled. It is possible to override
default ControlPort and DataPort, if there is any other
application that already listens on those two ports.
Server Mode
To conduct tests, ovs-l3ping
server must be running. It is
required that both client and server InnerIP addresses are in the
same subnet. It is possible to specify InnerIP with netmask in
CIDR format.
Параметры (Options)
One of -s
or -c
is required. The -t
option is also required.
-s
TunnelRemoteIP,InnerIP[/mask][:ControlPort]
--server
TunnelRemoteIP,InnerIP[/mask][:ControlPort]
Run in server mode and create L3 tunnel with the client
that will be accepting tunnel at TunnelRemoteIP address.
The socket on InnerIP[:ControlPort] will be used to
receive further instructions from the client.
-c
TunnelRemoteIP,InnerIP[/mask][:ControlPort[:DataPort]],RemoteInnerIP[:ControlPort[:DataPort]]
--client
TunnelRemoteIP,InnerIP[/mask][:ControlPort[:DataPort]],RemoteInnerIP[:ControlPort[:DataPort]]
Run in client mode and create L3 tunnel with the server on
TunnelRemoteIP. The client will use InnerIP to generate
test traffic with the server's RemoteInnerIP.
-b
targetbandwidth
--bandwidth
targetbandwidth
Target bandwidth for UDP tests. The targetbandwidth must
be given in bits per second. It is possible to use postfix
M or K to alter the target bandwidth magnitude.
-i
testinterval
--interval
testinterval
How long each test should run. By default 5 seconds.
-t
tunnelmode
--tunnel-mode
tunnelmode
Specify the tunnel type. This option must match on server
and client.
-h
--help
Prints a brief help message to the console.
-V
--version
Prints version information to the console.
Примеры (Examples)
On host 192.168.122.220 start ovs-l3ping
in server mode. This
command will create a temporary GRE tunnel with the host
192.168.122.236 and assign 10.1.1.1/28 as the inner IP address,
where client will have to connect:
ovs-l3ping -s 192.168.122.236,10.1.1.1/28 -t gre
On host 192.168.122.236 start ovs-l3ping
in client mode. This
command will use 10.1.1.2/28 as the local inner IP address and
will connect over the L3 tunnel to the server's inner IP address
at 10.1.1.1.
ovs-l3ping -c 192.168.122.220,10.1.1.2/28,10.1.1.1 -t gre
