Why would all of the devices on this switch be having an average Transmit Rate (Mbps) of over 3 Mbps? That seems like it's too high? Is it too high, or is that where they should be at? No computers are doing updates or heavy surfing of the web. How do I go about solving this issue? I have IP Phones attached to this switch and the computers at their desks are connected to the back of the IP phone for network connection. The phones are now having issues. The line sounds garbled at times, sometimes we lose a word every 3 to 5 words. I've even heard reports of a few calls being dropped. The switch is a Dell PowerConnect 3548.

Here's the picture of the statistic page of the switch that I'm referring to above. Switch Port Statistic Picture

yes, switch may be going bad, if you have a spare just replace it and see what happens.
basically you have 2 possibilities:
1. the switch is bad, there is no traffic, just seems so.
2. the switch is right, something is really generating all that traffic, you have to find out what

yes, a virus can propagate over the network

did you try power cycling the switch?

i would focus on a single workstation connected to that switch, figure out what is generating this traffic.

THANKS so much for your quick response. Following are my answers to your proposed solutions:
1. I looked for a loop already and did not find one. The switch's STP settings have always been enabled as well.
2. Running virus scans on workstations. Could it be a virus contaminated a computer and then moved to all the other computers on that switch?
3. No one is streaming audio/video (looked for audio/video streaming going on through our web filter and did not see any going on)
4. No one is downloading torrents. That type of peer-to-peer is blocked in our network.

Is it possible that the switch may be going bad? It hasn't cut out or given me any other indications that it's going bad.

Thanks gbb0330 for the input. Replaced the switch and the problem went away, thus leading us to conclude that bgg0330's #1 possibility was correct. You are awesome!
