As you can see that some interfaces have mtu errors hugeee. why don't these interfaces have any Drops or Errors.... If there is no any Drops and Errors, can we understant these interfaces are okay and in normal operating? If you think no....What troucleshooting must be done? And what reason behind this mtu errors?
The MTU errors that you are seeing are seen as the Output errors on the respective interfaces.
It simply means that there are some big packets which are exiting the interfaces and it does not necessarily mean that the packet is being dropped at the output of the interface.
You can check the MTU settings on the local interfaces and the remote side MTU.
There will be packet drop only in the situation where transit packets whose packet size is bigger than the MTU of the outgoing interface, and if the DF (Do-Not-Fragment) bit is set in the packet header, these packets will be dropped at the outgoing interface and output MTU errors will be counted.
For that you need to check if the MTU errors are incrementing.
