How can I know if ipv6 is running or active on my AIX system.

Hi there,

I need to know if ipv6 is running on my AIX machine. I am running AIX v5.4. I don't need to disable or enable it. I just want to know if it is running or not.

on Linux i can get that info by running modprobe -c | grep net-pf-10

Thanks.

Hello,

I'm not sure if this will answer your question. I use:

Code:

lsattr -EH -l en0

on AIX5.3 which gives me:

Code:

tcp_sendspace             Set Socket Buffer Space for Sending        True

On this server IPv6 is active but not configured (only on loopback).

Code:

[root@srvi2dbd:/]ifconfig -a

        inet6 ::1/0
         tcp_sendspace 131072 tcp_recvspace 131072 rfc1323 1

Hope this helps.

Kind regards,
