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

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:

attribute    value      description                                user_settable



alias4                    IPv4 Alias including Subnet Mask          True

alias6                    IPv6 Alias including Prefix Length        True

arp          on          Address Resolution Protocol (ARP)          True

authority                Authorized Users                          True

broadcast                Broadcast Address                          True

mtu          1500        Maximum IP Packet Size for This Device    True

netaddr      10.1.1.2    Internet Address                          True

netaddr6                  IPv6 Internet Address                      True

netmask      255.255.0.0 Subnet Mask                                True

prefixlen                Prefix Length for IPv6 Internet Address    True

remmtu        576        Maximum IP Packet Size for REMOTE Networks True

rfc1323                  Enable/Disable TCP RFC 1323 Window Scaling True

security      none        Security Level                            True

state        up          Current Interface Status                  True

tcp_mssdflt              Set TCP Maximum Segment Size              True

tcp_nodelay              Enable/Disable TCP_NODELAY Option          True

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

en0: flags=1e080863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),LARGESEND,CHAIN>

        inet 10.1.1.2 netmask 0xffff0000 broadcast 10.1.255.255

        inet 172.25.2.37 netmask 0xffff0000 broadcast 172.25.255.255

        inet 10.3.1.1 netmask 0xffff0000 broadcast 10.3.255.255

        tcp_sendspace 131072 tcp_recvspace 65536 rfc1323 0

en1: flags=1e080863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),LARGESEND,CHAIN>

        inet 10.2.1.2 netmask 0xffff0000 broadcast 10.2.255.255

        inet 10.4.1.1 netmask 0xffff0000 broadcast 10.4.255.255

        inet 172.25.2.2 netmask 0xffff0000 broadcast 172.25.255.255

        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
