New Revision: 284365
URL: https://svnweb.freebsd.org/changeset/base/284365
Log:
MFC r273331, r273371, r275851:
- Add vxlan interface
- Use the size of the Ethernet address, not the entire header, when
copying into forwarding entry.
- Prefix all the vxlan ifconfig commands so they are unique
Added:
stable/10/sbin/ifconfig/ifvxlan.c
- copied, changed from r273331, head/sbin/ifconfig/ifvxlan.c
stable/10/share/man/man4/vxlan.4
- copied, changed from r273331, head/share/man/man4/vxlan.4
stable/10/sys/modules/if_vxlan/
- copied from r273331, head/sys/modules/if_vxlan/
stable/10/sys/net/if_vxlan.c
- copied, changed from r273331, head/sys/net/if_vxlan.c

The following parameters are used to configure
+.Xr vxlan 4
+interfaces.
+.Bl -tag -width indent
+.It Cm vxlanid Ar identifier
+This value is a 24-bit VXLAN Network Identifier (VNI) that identifies the
+virtual network segment membership of the interface.
+.It Cm vxlanlocal Ar address
+The source address used in the encapsulating IPv4/IPv6 header.
+The address should already be assigned to an existing interface.
+When the interface is configured in unicast mode, the listening socket
+is bound to this address.
+.It Cm vxlanremote Ar address
+The interface can be configured in a unicast, or point-to-point, mode
+to create a tunnel between two hosts.
+This is the IP address of the remote end of the tunnel.
+.It Cm vxlangroup Ar address
+The interface can be configured in a multicast mode
+to create a virtual network of hosts.
+This is the IP multicast group address the interface will join.
+.It Cm vxlanlocalport Ar port
+The port number the interface will listen on.
+The default port number is 4789.
+.It Cm vxlanremoteport Ar port
+The destination port number used in the encapsulating IPv4/IPv6 header.
+The remote host should be listening on this port.
+The default port number is 4789.
+Note some other implementations, such as Linux,
+do not default to the IANA assigned port,
+but instead listen on port 8472.
+.It Cm vxlanportrange Ar low high
+The range of source ports used in the encapsulating IPv4/IPv6 header.
+The port selected within the range is based on a hash of the inner frame.
+A range is useful to provide entropy within the outer IP header
+for more effective load balancing.
+The default range is between the
+.Xr sysctl 8
+variables
+.Va net.inet.ip.portrange.first
+and
+.Va net.inet.ip.portrange.last
+.It Cm vxlantimeout Ar timeout
+The maximum time, in seconds, before an entry in the forwarding table
+is pruned.
+The default is 1200 seconds (20 minutes).
+.It Cm vxlanmaxaddr Ar max
+The maximum number of entries in the forwarding table.
+The default is 2000.
+.It Cm vxlandev Ar dev
+When the interface is configured in multicast mode, the
+.Cm dev
+interface is used to transmit IP multicast packets.
+.It Cm vxlanttl Ar ttl
+The TTL used in the encapsulating IPv4/IPv6 header.
+The default is 64.
+.It Cm vxlanlearn
+The source IP address and inner source Ethernet MAC address of
+received packets are used to dynamically populate the forwarding table.
+When in multicast mode, an entry in the forwarding table allows the
+interface to send the frame directly to the remote host instead of
+broadcasting the frame to the multicast group.
+This is the default.
+.It Fl vxlanlearn
+The forwarding table is not populated by recevied packets.
+.It Cm vxlanflush
+Delete all dynamically-learned addresses from the forwarding table.
+.It Cm vxlanflushall
+Delete all addresses, including static addresses, from the forwarding table.
