noticed the pattern of the up/down.....down...up...down...up. this maybe the normal behavior for this host. it's only happen 3 times in 3 days.
if you get 10 or more up/down in a minute, that's what I call link flap. chk the switchport for errors. I would expect you see a few errors. clear the counters and check for error in a day or two. as long as the interface shows pretty clean, then there is nothing to worry.
I have a too that problem, but it started a while ago, on all switches (40-2950+2960) some interfaces are going down & up for 2 seconds, when they are on switchport portfast the line protocol just go down & up, without goes the link too for 3 seconds. I dont know what it is this doing. Its too often to be normal
