Static IP on multiple NICs in OpenIndiana with NWAM
I wanted to set one of the NICs on my OI box to have a static since it's got a direct connection to my ESX box, bypassing any switches, and directly linked to a VM on that machine. I routinely transfer large chunks of data (1-20GB files) from that VM to my OI box, so I wanted to completely move that off of my main network. The VM is a Windows box, and I have the NIC set statically to 192.168.20.1/30 and wanted to set the OI box to .2. However, I couldn't find a simple way to do it with ifconfig, and everything I found suggested disabling the NWAM service and switching to the old way of doing things, which is bad. Apparently.
At any rate, disabling the service that was in charge of how my NICs were configured didn't seem like a good idea with a headless box, only accessible via SSH. So, I kimmed some pages about what the NWAM service does and how to use it I started looking for better examples of how to use it and stumbled across this page. I figured out how to create my own profile with one static, and one DHCP link.
In order to do this you need to use nwamcfg to create a new Network Configuration Profile , and then setup both NICs in the profile as Network Configuration Units with their desired options, then activate the profile.
First, run nwamcfg under root, then do:
$ nwamcfg nwamcfg> create ncp profile #Create the profile nwamcfg:ncp:profile> create ncu phys nic0 #Add the layer 2 config for nic0 Created ncu 'nic0'. Walking properties ... # Set prioritized so that it starts at boot. activation-mode (manual) [manual|prioritized]> prioritized # Leave default for enabled. enabled (true) [true|false]> # 0 for ethernet (802.3) 1 for wifi (802.11) priority-group> 0 # exclusive means only 1 NCU (NIC) in the group # shared means any of the NCUs can be active # all means all of the NCUs must be available to be active priority-mode [exclusive|shared|all]> shared # Leave the default MAC link-mac-addr> # Configures autopush settings, modules to be added I dunno... link-autopush> # Set MTU, I have jumbo frames link-mtu> 9126 nwamcfg:ncp:profile:ncu:nic0> end Committed changes # Create the Layer 2 settings for nic1 nwamcfg:ncp:profile> create ncu phys nic1 Created ncu 'nic1'. Walking properties ... activation-mode (manual) [manual|prioritized]> prioritized enabled (true) [true|false]> priority-group> 0 priority-mode [exclusive|shared|all]> shared link-mac-addr> link-autopush> link-mtu> 9126 nwamcfg:ncp:profile:ncu:nic1> end Committed changes # Create layer 3 settings for nic0 nwamcfg:ncp:profile> create ncu ip nic0 Created ncu 'nic0'. Walking properties ... enabled (true) [true|false]> # Select which IP version you want, both here ip-version (ipv4,ipv6) [ipv4|ipv6]> ipv4-addrsrc (dhcp) [dhcp|static]> static # Use CIDR notation ipv4-addr> 192.168.2.0.2/30 # Set your default route, blank cause I don't need one here ipv4-default-route> # Set ipv6, options, not using it, not set. ipv6-addrsrc (dhcp,autoconf) [dhcp|autoconf|static]> ipv6-default-route> nwamcfg:ncp:profile:ncu:nic0> end Committed changes # Configure layer 3 settings for nic1 nwamcfg:ncp:profile> create ncu ip nic1 Created ncu 'nic1'. Walking properties ... enabled (true) [true|false]> ip-version (ipv4,ipv6) [ipv4|ipv6]> ipv4-addrsrc (dhcp) [dhcp|static]> ipv4-default-route> ipv6-addrsrc (dhcp,autoconf) [dhcp|autoconf|static]> ipv6-default-route> nwamcfg:ncp:profile:ncu:nic1> end Committed changes nwamcfg:ncp:profile> end nwamcfg> end # Enable the profile $ nwamadm enable -p ncp profile
