For IPSO devices a useful command is:

    # ipsctl -a | grep linktransitions

This will tell you how many times the link has bounced on each port.

One of our more flaky IP650's shows this:

    ifphys:eth-s2p1:stats:linktransitions = 23
    ifphys:eth-s2p2:stats:linktransitions = 245    <<< not good
    ifphys:eth-s2p3:stats:linktransitions = 13
    ifphys:eth-s2p4:stats:linktransitions = 5

This is our most typical failure on IP650's, the quad nics start
generating link transitions, getting progressively worse until the card
must be replaced.
