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_recvspace             Set Socket Buffer Space for Receiving      True
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

         tcp_sendspace 131072 tcp_recvspace 65536 rfc1323 0
lo0: flags=e08084b<UP,BROADCAST,LOOPBACK,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT>
        inet 127.0.0.1 netmask 0xff000000 broadcast 127.255.255.255
        inet6 ::1/0
         tcp_sendspace 131072 tcp_recvspace 131072 rfc1323 1
Hope this helps.

Kind regards,

Eric
