I renumbered my 3750 switches over the weekend, and the port that my router is connected to is at > 95% load occasionally. I can't run netflow on these switches, so what do you recommend? I need to figure out why this is so high.
GigabitEthernet5/0/5 is up, line protocol is up (connected)
Hardware is Gigabit Ethernet, address is 0015.f937.6785 (bia 0015.f937.6785)

The port is trunked to the router, and I haven't noticed it in the past, but it seems that most of the time it's been at least once every 30 minutes that I'm seeing this load. Anything I should look at?
Thanks,
