In v4, all "server" sections MUST start with a "namespace" parameter. This tells the server which protocol is being used.
All of the subsequent "listen" sections in this server will only accept packets for that protocol.
- transport
- type
-
Type of VMPS packets to listen for.
- ipaddr
-
VMPS sockets only support IPv4 addresses.
- port
-
Port on which to listen.
| 1589 is the default VMPS port. |
Some systems support binding to an interface, in addition to the IP address. This feature isn’t strictly necessary, but for sites with many IP addresses on one interface, it’s useful to say "listen on all addresses for eth0".
If your system does not support this feature, you will get an error if you try to use it.
You can list multiple "client" sections here in order to define clients which apply only to this virtual server. i.e. only for the VMPS protocol.
This section is called when it receives a Join-Request.
Some requests may not have a MAC address. Try to create one using other attributes.
Do a simple mapping of MAC to VLAN.
See raddb/mods-available/mac2vlan for the definition of the "mac2vlan"
module.
required VMPS reply attributes
If you have VLAN’s in a database, you can select
the VLAN name based on the MAC address.

This section is called when it sends a Join-Response.
This section is called when it receives a Reconfirm-Request.
