[H/W] Interface Transmit Errors

I am getting transmission errors on a Fast Ethernet interface with a relatively low amount of traffic (~3.2mbps):

068779: .Jul 20 15:12:25.605 EST: %AMDP2_FE-5-LATECOLL: FastEthernet2/0 transmit error
068780: .Jul 20 15:12:27.317 EST: %AMDP2_FE-5-LATECOLL: FastEthernet2/0 transmit error
068781: .Jul 20 15:12:29.397 EST: %AMDP2_FE-5-LATECOLL: FastEthernet2/0 transmit error
068782: .Jul 20 15:12:30.881 EST: %AMDP2_FE-5-LATECOLL: FastEthernet2/0 transmit error
068783: .Jul 20 15:12:41.641 EST: %AMDP2_FE-5-LATECOLL: FastEthernet2/0 transmit error
068784: .Jul 20 15:12:44.341 EST: %AMDP2_FE-5-LATECOLL: FastEthernet2/0 transmit error

Any ideas as to what the cause of these could be?

duplex mismatch most likely.

This is what I am seeing as to errors on that interface:

What's the device and IOS type?

Also verify that both peers are in the same duplex mode.

This is a Cisco 3640 running IOS 12.3(10)T... duplex is set correctly.

Are you sure that the duplex setting match on both sides? The router post %AMDP2_FE-5-LATECOLL error message, which mean there is a late collision error that most of the time is caused by mismatched duplex settings. Here is the Cisco link for more info on the error message:

»www.cisco.com/en/US/tech/tk389/t···6d.shtml

Ground rule is that both sides (your router and the other equipment) should be in the same setting; either auto, full, or half duplex.

It's an optical interface, so unfortunately, there is no auto-negotiation.

I am waiting for the NM-2FE2W-V2 module to arrive so I could replace our LAN interfaces, and this way I would be able to run full-duplex Fast Ethernet.

Other than hardware failure (which is generally more spectacular), you should not see that error on a full-duplex interface. If you are, something's not at full-duplex (no matter what the layer-1 medium is).

What's at the other end? What hooks up to what's at the other end?

I had something similar to this.....I upgraded my IOS and then shut everything down and it was fine.
