I have a port channel setup with each of the member ports reporting various errors. Here is what I have for each port using the show int counters errors command:
Port Align-Err FCS-Err Xmit-Err Rcv-Err UnderSize OutDiscards
Gi1/0/1 0 1582 0 1582 0 1637667
Port Single-Col Multi-Col Late-Col Excess-Col Carri-Sen Runts Giants
Gi1/0/1 0 0 0 0 0 0 0
Port Align-Err FCS-Err Xmit-Err Rcv-Err UnderSize OutDiscards
Gi2/0/1 0 4456 0 4456 0 2704033
Port Single-Col Multi-Col Late-Col Excess-Col Carri-Sen Runts Giants
Gi2/0/1 0 0 0 0 0 0 0
This port channel is an uplink to another switch. Can someone help me figure out what might be the issue in relation the errrors being displayed? Thanks!!

Looks like a physical issue , try changing the media in the path between those 2 devices. Are these gig links or lower speed ?

I'm with Glen. FSC errors are Frame Check Sequence errors - these usually indicate bad cabling. if these are 1 gig ports, change your cabling to Cat5E at minimum (Cat6 is better) and check your termiantions etc if they're punch panels.

Excellent. I figured it would be something easy. Thanks for the replys.

If Gig 1/0/1 is copper, then run a simple TDR.
Post the output of the command "sh cable tdr int Gi1/0/1" if you want some assistance.
