I have a 3750G switch that is experiencing horrible speeds with ports gig 1 - 4
All other ports 5 - 24 are working good.
When connecting servers to these ports, I am getting horrible file tranfer speeds.
I connect to other ports and moving files at over 100 megabit.
Now I check the controller
#show controllers ethernet-controller gigabitEthernet 1/0/1
"1446725 Too old frames"
I get "Too old frames" on interfaces g1/0/1 - 4
All other Interfaces , it shows up as 0 Tool old frames.
I came to the conclusion that there might be a problem with these actual switch ports.
It states that "Too old frames" are "Packets discared on egress due to being aged out"
What can be causing this? Is this a hardware failure?
I checked:
Speed, duplex, changed network cable (cat 5 & 6)
Anyone have any ideas?

I have a hunch that this is a hardware problem. I recall that Cisco Catalyst switches share a single PHY for every 4 or 8 consecutive switchports. In other words, a problem with one PHY or on any of its support circuitry, the problem can show up in more than one switchport, usually in groups of 4 or 8.

I fear that you are correct.
