We are a ISP . In our PE cisco router , we received logs :
.Jun 8 17:40:14:%LINK-4-TOOBIG: Interface FastEthernet1/1/0,Output packet size of 1558 bytes too big
I have refered to cisco teach support . Find a message like it :
Error Message
%LINK-4_TOOBIG : Interface [chars], output packet size of [dec]bytes too big
Explanation An internal software error has occurred
Recommended Action Copy the error message exactly as it appears on the console or in the system log, contact your Cisco technical support representaive, and provide the representative with the gathered information.
The question is What internal software refer to ? If it means the cisco ios has error or the soft of client has error ?
Thank you.....
