File descriptor interface driver
Syntax:
io-pkt-variant -d fd fd=device[,option[,option ...]] ... &
where variant is one of v4, v4-hc, or
v6-hc.
Options:
Note:
Use commas, not spaces, to separate the options.
- ahdlc
- Read or write packet data in AHDLC frame format.
- fd=device
- The device on which to open the file descriptor to read or write packet data.
You must specify this option.
- lan=num
- The LAN number. The default is 0.
- mac=XXXXXXXXXXXX
- The MAC address of the controller. There is no default.
- mru=num
- Maximum receive unit. The default is 1514.
- mtu=num
- Maximum transmission unit.
The default (1514) is automatically detected on supported hardware.
- nomulticast
- Disable multicast support.
- priority=N
- Priority of the driver event-thread. The default is 21.
- promiscuous
- Enable promiscuous mode. The default is off.
- verbose or verbose=num
- Be verbose. Specify num for more verbosity (num can be 1-4, the higher
the number, the more detailed the output). The default is 0.
The output goes to slogger,
invoke sloginfo to view.
Description:
The devn-fd.so driver uses file-descriptor based I/O
(i.e., open(), read(),
write(), and so on) to receive and transmit packets.
It provides the Network Manager
(io-pkt*)
with reliable data transfer over any media
supported by a file-descriptor-based server process.
Note:
The devn-fd.so driver doesn't support multicast addresses.
For example, you could use devn-fd.so to connect two machines
with a null-modem RS-232 serial cable.
By using file-descriptor I/O to the serial devices, devn-fd.so
would implicitly use a serial driver and set up a logical network link.
This is a legacy io-net driver;
its interface names are in the form enX, where
X is an integer.
Examples:
Start io-pkt-v4-hc using the FD driver:
io-pkt-v4-hc -d fd fd=/dev/ser1,mac=0023456789AB,ahdlc
ifconfig en0 10.0.184
Files:
- /dev/io-net
- The directory where, by default, drivers and protocol modules add entries.
For more information, see the documentation for
io-pkt*.
Caveats:
You must specify the fd option when using this driver.
