Monitoring IPv6

The following commands were modified to accommodated the Solaris implementation of IPv6.

You can use the new additions to conduct diagnostics. For conceptiual descriptions of these commands, see Extensions to the ifconfig Utility in Chapter 1 and Extensions to Existing Utilities in Chapter 1.

Table 2-2. Monitoring IPv6 Task Map

Task

Description

For Instructions, Go to

1. Display interface address assignments

Displays all, or just IPv4, or just IPv6 address assignments using ifconfig command.

How to Display Interface Address Assignments

2. Display network status

Displays all sockets and routing table entries, inet address family for Ipv4, inet6 address family for IPv6, and statistics per interface IPv6/ICMPv6 counters using netstat command.

How to Display Network Status

3. Control the display output

Controls the output of the ping, netstat, ifconfig, and traceroute commands by creating a file named inet_type and setting the DEFAULT_IP variable in it.

How to Control the Display Output

4. Monitor only IPv6 network traffic

Displays all IPv6 packets using the snoop command.

How to Monitor Only IPv6 Network Traffic

5. Probe all multihomed host addresses

Checks all addresses using the ping command.

How to Probe All Multihomed Host Addresses

6. Trace all routes

Traces all routes using the traceroute command.

Procedure How to Display Interface Address Assignments

You can use the ifconfig command to display all address assignments as well as just IPv4 or IPv6 address assignments.

For more information on the ifconfig command, see the ifconfig(1) man page.

Example--ifconfig a Command

Procedure How to Display Network Status

These procedures enable you to display the following network data structure formats using the netstat command:

For more information on the netstat command, see the netstat(1) man page.

Procedure How to Control the Display Output

You can control the output of the netstat and ifconfig commands by creating a file named inet_type in the /etc/default directory and specifying the value of the DEFAULT_IP variable.

  1. Create the /etc/default/inet_type file.

  2. Make one of the following entries as needed.
    1. To display IPv4 information only, enter:
      DEFAULT_IP=IP_VERSION4

    2. To display IPv6 information only, enter:
      DEFAULT_IP=IP_VERSION6

    3. To display both IPv4 and IPv6 information, enter:
      DEFAULT_IP=BOTH

Note - The -4 and -6 flags in ifconfig and -f flag in netstat override the value set in the inet_type file (if it exists).

Examples--Controlling Output of ifconfig Command

Procedure How to Monitor Only IPv6 Network Traffic

In this procedure you use the snoop command to display all IPv6 packets.

  1. Become superuser.

  2. On the command line, type the following command.
    # snoop ipv6

For more information on the snoop command, see the snoop(1) man page.

Example--snoop Command

# snoop ip6

Procedure How to Probe All Multihomed Host Addresses

In this procedure you use the ping command to check all addresses.

For more information on the ping command, see the ping(1) man page.

Example--ping Command

% ping -a ipng11

ipng11 (2::102:a00:20ff:fe79:19b0) is alive
ipng11 (fec0::102:a00:20ff:fe79:19b0) is alive
ipng11 (192.168.10.75) is alive

Procedure 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(1) man page.
