CRC errors mostly point out to physical layer issues.

Check the cables and replace if necessary

Try different speed and duplex settings on the port and check for errors.

clear the counters and check if these errors are still increasing

Yes, I agree. Most of the time, CRC's point to physical layer problems.

Is your bridge managed? Do you have any info from that?

What are your port/duplex settings on both sides?

Those errors could almost be anything , first the counters have never been cleared since the box was last rebooted whenever that was . There may not even be a problem at this point.

1. Issue "clear counters" command on both ends.

2. If errors add up, try "speed auto" and "duplex auto" on all ports

3. If errors add up, try "speed 100" and "duplex full" on all ports

4. If errors add up, try "speed 100" and "duplex half" on all ports.

Clear counters after each try and observe results.
