Testing physical network connection

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. But is there any better way to see if you have good layer 2 connectivity?

KERBEROS(8)						    BSD System Manager's Manual 					       KERBEROS(8)

NAME

     kerberos -- introduction to the Kerberos system

DESCRIPTION

     Kerberos is a network authentication system. Its purpose is to securely authenticate users and services in an insecure network environment.

     This is done with a Kerberos server acting as a trusted third party, keeping a database with secret keys for all users and services (collec-
     tively called principals).

     Each principal belongs to exactly one realm, which is the administrative domain in Kerberos. A realm usually corresponds to an organisation,
     and the realm should normally be derived from that organisation's domain name. A realm is served by one or more Kerberos servers.

     The authentication process involves exchange of 'tickets' and 'authenticators' which together prove the principal's identity.

     When you login to the Kerberos system, either through the normal system login or with the kinit(1) program, you acquire a ticket granting
     ticket which allows you to get new tickets for other services, such as telnet or ftp, without giving your password.

     For more information on how Kerberos works, and other general Kerberos questions see the Kerberos FAQ at
     http://www.nrl.navy.mil/CCS/people/kenh/kerberos-faq.html.

     For setup instructions see the Heimdal Texinfo manual.

HISTORY

     The Kerberos authentication system was developed in the late 1980's as part of the Athena Project at the Massachusetts Institute of Technol-
     ogy. Versions one through three never reached outside MIT, but version 4 was (and still is) quite popular, especially in the academic commu-
     nity, but is also used in commercial products like the AFS filesystem.

     The problems with version 4 are that it has many limitations, the code was not too well written (since it had been developed over a long
     time), and it has a number of known security problems. To resolve many of these issues work on version five started, and resulted in IETF RFC
     1510 in 1993. IETF RFC 1510 was obsoleted in 2005 with IETF RFC 4120, also known as Kerberos clarifications. With the arrival of IETF RFC
     4120, the work on adding extensibility and internationalization have started (Kerberos extensions), and a new RFC will hopefully appear soon.

     This manual page is part of the Heimdal Kerberos 5 distribution, which has been in development at the Royal Institute of Technology in Stock-
     holm, Sweden, since about 1997.
