How to Control the Display Output of IPv6 Related Commands
You can control the output of the netstat and ifconfig commands. Create a file that is named inet_type in the /etc/default directory. Then specify the value of the DEFAULT_IP variable. For more information about the inet_type, see the inet_type(4) man page.
Create the /etc/default/inet_type file.
Make one of the following entries, as needed.
To display IPv4 information only, type:
DEFAULT_IP=IP_VERSION4
To display both IPv4 and IPv6 information, type:
DEFAULT_IP=BOTH
or
DEFAULT_IP=IP_VERSION6
Note - The -4 and -6 flags in ifconfig override the value set in the inet_type file. The -f flag in netstat also overrides the value that is set in the inet_type file.
Examples--Controlling Output to Select IPv4 and IPv6 Information
When you specify the DEFAULT_IP=BOTH or DEFAULT_IP=IP_VERSION6 variable in the inet_type file, you should have the following results:
% ifconfig -a lo0: flags=1000849 mtu 8232 index 1 inet 120.10.0.1 netmask ff000000 le0: flags=1000843 mtu 1500 index 2 inet 120.46.86.54 netmask ffffff00 broadcast 120.46.86.255 ether 8:0:20:56:a8 lo0: flags=2000849 mtu 8252 index 1 inet6 ::1/128 le0: flags=2000841 mtu 1500 index 2 ether 8:0:20:56:a8 inet6 fe80::a00:fe73:56a8/10 le0:1: flags=2080841 mtu 1500 index 2 inet6 fec0::56:a00:fe73:56a8/64 le0:2: flags=2080841 mtu 1500 index 2 inet6 2::56:a00:fe73:56a8/64When you specify the DEFAULT_IP=IP_VERSION4 variable in the inet_type file, you should have the following results:
% ifconfig -a lo0: flags=849 mtu 8232 inet 120.10.0.1 netmask ff000000 le0: flags=843 mtu 1500 inet 120.46.86.54 netmask ffffff00 broadcast 120.46.86.255 ether 8:0:20:56:a8
How to Monitor Only IPv6 Network Traffic
In this procedure, you use the snoop command to display all IPv6 packets.
For more information on the snoop command, see the snoop(1M) man page.
Example--Displaying Only IPv6 Network Traffic
# snoop ip6 Using device /dev/le (promiscuous mode) fe80::a0:a1 -> ff02::9 IPv6 S=fe80::a0:a1 D=ff02::9 LEN=892 fe80::a0:de -> fe80::a0:a8 IPv6 S=fe80::a0:de D=fe80::a0:a8 LEN=104 fe80::a0:a8 -> fe80::a0:de IPv6 S=fe80::a0:a8 D=fe80::a0:de LEN=104 fe80::a0:a1 -> ff02::9 IPv6 S=fe80::a0:a1 D=ff02::9 LEN=892 fe80::a0:de -> fe80::a0:a8 IPv6 S=fe80::a0:de D=fe80::a0:a8 LEN=104 fe80::a0:a8 -> fe80::a0:de IPv6 S=fe80::a0:a8 D=fe80::a0:de LEN=152 fe80::a0:a1 -> ff02::9 IPv6 S=fe80::a0:a1 D=ff02::9 LEN=892 fe80::a0:de -> fe80::a0:a8 IPv6 S=fe80::a0:de D=fe80::a0:a8 LEN=72 fe80::a0:a8 -> fe80::a0:de IPv6 S=fe80::a0:a8 D=fe80::a0:de LEN=72 fe80::a0:a8 -> fe80::a0:de IPv6 S=fe80::a0:a8 D=fe80::a0:de LEN=72 fe80::a0:de -> fe80::a0:a8 IPv6 S=fe80::a0:de D=fe80::a0:a8 LEN=72 |
How to Probe All Multihomed Host Addresses
In this procedure, you use the ping command to check all addresses.
On the command line, type the following command.
% ping -a ipng11 ipng11 (2::102:a00:fe79:19b0) is alive ipng11 (fec0::102:a00:fe79:19b0) is alive ipng11 (190.68.10.75) is alive
For more information on the ping command, see the ping(1M) man page.
How to Trace All Routes
In this procedure, you use the traceroute command to trace all routes.
For more information on the traceroute command, see the traceroute(1M) man page.
