Pinned topic Disable IPV6 on VIOS

‏2013-02-21T17:31:17Z |
I found some pretty good instructions on how to disable IPV6 here: http://www.aixmind.com/?p=1858 . The only thing I couldn't do was the final step which involved editing the /etc/netsvc.conf file. ALL of the entries in that file had been commented out so the instructions, which said to change the settings, didn't directly apply. I added an entry which was 'hosts = local4,bind4' but that seemed to make no difference. With Wireshark I am seeing DHCPV6 solict requests that appear to be coming from the NIC on the blade running VIOS.

I am wondering if VIOS in this case handles the enable/disable of IPV6 differently than AIX? I used smitty to look at the settings and couldn't see anything. A quick pointer on where to disable IPV6 (for diagnostics on a connection issue) would be helpful.

    Not sure what you mean by -> that appear to be

    Is the MAC address identical ? or off by a few octets ?

    Regardless, you might want to check the AMM.

    Login in to the AMM
    • go to > Blade Tasks
    • then > Configuration
    • then > Management Network tab
    • then > click on the Power / VIO Blade
    • should be on a Bay XX _______ : Network Management screen
    • review the setting there for eth0, disable DHCPv6, etc. and save it

    Not saying that's where your v6 traffic is coming from.... but one never knows :)

    Good luck

      Slight correction:

      • should be on a Bay XX _______ : Network Management screen

      should read

      • should be on a Bay XX - _______ : Network Configuration screen

    Interestingly, IPV6 was not enabled there only IPV4, but I disabled the management interface for that blade and the IPV6 solicit requests stopped. Somehow, even with IPV6 not enabled, those solicit requests were still going out. Disabling the management network interface stopped the requests.
