How to Monitor IPv6 Network Traffic

You can use the snoop command to display only IPv6 packets.

1. On the local node, assume the Network Management role or become superuser.

   Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

2. Capture IPv6 packets.

   # snoop ip6

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

The following example shows typical output such as you might receive from running the snoop ip6 command on a node.

# snoop ip6
