Hi .. it seems that some ports on your switch are receiving packets at a higher rate that it can currently handle ( be aware that ports are surrently configuring to 100Mbps but they can support 1000 Mbps. This is causing those switch ports to have output errors. Please see the below results from Cisco Output Interpreter.
SHOW INTERFACE FAST/GIGABIT/ETHERNET NOTIFICATIONS (if any)
Interface GigabitEthernet2/7 (up/up)
WARNING: The counters have never been cleared on this interface and may not accurately
reflect the current status of this interface.
TRY THIS: Use the 'clear counters' command to reset the counters and monitor the
interface parameters over time (less than 24 hours). Reset the counters and wait
a few minutes to resubmit the output to Output Interpreter.
WARNING: The input queue is 193.4% full and could indicate a potential 'wedged
interface' buffer leak.
Once an interface is wedged, the router will stop forwarding traffic coming from
the affected interface.
TRY THIS: Use the 'show buffers old' and 'show buffers input-interface GigabitEthernet2/7'
commands to pinpoint the source of the buffer leak.
WARNING: There have been 394564 'output errors' reported.
Output error refers to the number of times, receiver hardware is unable to handover
the received data, to an outgoing hardware buffer. This occurs when the input
rate exceeds the receiver's ability to handle the data. Also, output error is
the sum of all errors that prevented the final transmission of datagrams out
of the interface being examined. This may not balance with the sum of the enumerated
output errors, as some datagrams may have more than one error, and others may
have errors that do not fall into any of the specifically tabulated categories.
TRY THIS: Monitor the level of output errors over time, if this is steadily increasing,
do the following.
1. Verify the proper duplex and speed have been configured on the interface.
2. Review Bug Toolkit for potential bugs related to Output Errors.
3. Review hardware troubleshooting procedures for your product at Product Support.
