How do you test the physical network connection of an interface in solaris. I know that if you have an active connection and the cable gets yanked, you can look in the messages file to check for link failure messages.

PROTOCOLS(5) Linux Programmer's Manual PROTOCOLS(5)
NAME
protocols - the protocols definition file
DESCRIPTION
This file is a plain ASCII file, describing the various DARPA internet protocols that are available from the TCP/IP subsystem. It should
be consulted instead of using the numbers in the ARPA include files, or, even worse, just guessing them. These numbers will occur in the
protocol field of any IP header.
Keep this file untouched since changes would result in incorrect IP packages. Protocol numbers and names are specified by the IANA (Inter-
net Assigned Numbers Authority).
Each line is of the following format:
protocol number aliases ...
where the fields are delimited by spaces or tabs. Empty lines are ignored. If a line contains a hash mark (#), the hash mark and the part
of the line following it are ignored.
The field descriptions are:
protocol
the native name for the protocol. For example ip, tcp, or udp.
number the official number for this protocol as it will appear within the IP header.
aliases
optional aliases for the protocol.
This file might be distributed over a network using a network-wide naming service like Yellow Pages/NIS or BIND/Hesiod.
FILES
/etc/protocols
The protocols definition file.
