How do I configure a dec interface

To setup a dec network interface do the following.

For dec interfaces that are mounted on the CPU boards (most motorola
platforms and TurboHawks) start at step 2.

For dec interfaces that are separate VME boards (or mounted on VME-PCI
bridge boards) start at step 1.

1.  Uncomment the appropriate dec line in /etc/conf/sadapters.d/kernel.

	# dec      0        pci0    intr  -       0          80804000  
	dec      0        pci0    intr  -       0          80804000  <-- uncommented

	
2.  Make sure the conf flag in /etc/conf/sdevice.d/dec is set to Y.

	$version 1
	$loadable dec

	#name   conf    unit
	dec     Y       0


3.  Uncomment the appropriate lines in the Node file /etc/conf/node.d/dec.

	#module node    type    minor   uid     gid     permissions   level
	#------------------------------------------------------------------
	clone   dec0    c:0     dec     0       3       0666            2
	#clone  dec1    c:1     dec     0       3       0666            2
	#clone  dec2    c:2     dec     0       3       0666            2


4.  If you modified either /etc/conf/sadapters.d/kernel or /etc/conf/sdevice.d/dec
rebuild the kernel and reboot the system otherwise proceed to step 6.

	# /etc/conf/bin/idbuild -K
	...
	# init 6
	....


5.  Check that the node file made the device correctly.

	# < /dev/dec0
	#

You should see no error messages.


6.  Add an entry for the dec in /etc/confnet.d/inet/interface.

	...
        #
        # Loopback interface
        #
        lo:0:localhost:/dev/loop::add_loop:
        #
        # Additional network interfaces
        #
	dec:0:sprocket:/dev/dec0:netmask 255.255.255.0 arp::

IMPORTANT: If this file is incorrect none of the network devices may work.
If this happens boot to single-user mode and re-edit the file.


7.  Reboot the system.

	# init 6
	....


8.  After the system comes up verify the interfaces are configured by running netstat -in.

        # netstat -in
        Name   Mtu   Network     Address      Ipkts   Ierrs Opkts   Oerrs Collis
        lo0    8232  127.0.0.0   127.0.0.1    13        0   13        0      0
        dec0   1500  129.134.136 129.134.136  82        0   14        0      0
